Hi all, from Australia. No gigabyte forums for us :(
Anyway, I have the GA-X58A-UD7, and I am suffering from High DPC latency, after some googling I found it may be the motherboard, and through testing it seems that this may be the issue.
Does anyone know if there is a planned fox for this?
To test DPC latency download the folling tool.
http://www.thesycon.de/deu/latency_check.shtml
I can spike above 1000, and at times, be above 25000 until I restart my PC. Which makes gaming/audio slow up and lag like hell.
Can a Bios update fix this?
-
Hi Cobber,
You might not have Gigabyte forums but you have VenGanZa and freinds on Whirlpool Forums. A very knowledgeable bunch too I might add.
If you do a search there was someone else complaining of the samething only the other day on this site. Anyway Gigabyte are working on an BIOS update for our board the UD7 at the moment so hopefully it wont be too long and will do the trick.

I know VenGanZa, good bloke.
Currently in the Sin Bin on whrilpool due to stepping over the mark with a comment about our new Prime Minister!
When I can post again I will ask on whirlpool, hope the new Bios is close.

I'm the one who also noticed excessive DPC latency on the UD7. I would get red spikes that went off the top of the chart, when doing normal things like browsing the net. When I turned off C1E and EIST, I didn't get the red spikes anymore. So you might want to try turning those power saving features off, to see if it fixes your problem for now.
The DPC latency problem has been reported to Gigabyte headquarters, they are currently working on a new BIOS that hopefully fixes it properly and the electrical noise buzzing problem.
PS. I am in Australia and post on Whirlpool too :) my name there is Lim^^

Cool 8) I will keep an eye out for both of you when I am next on(oh I forgot I am on there still) ;D Just remember no bad comments regarding the leadership!!

G'day Eastley mate.
Shame you got binned, must have been a hell of a comment (red heads rock btw).
Anyway, can you link us to whatever claims to mobo is to blame?
I find it hard to fathom, more often than not high latency or "spiking" is due to driver issues and suchlike.
Sadly if a ready solution can't be found, the only way I know of is to disable the whole lot progressively, and from memory DTP Latency page recommends just this.
I can tell you on my board *GA-X58A-UD9* my current latency is "0" with a maximum of "3" :)
Now of course my board is different, but I would be curious to read any literature of any substance that points the finger at your board.

Have a read, pages to go through that suggest the same as I have found, but my way of testing was as follows.
- DISABLE everything that you do not need in the bios, includes NIC, SOUND etc..
- Remove all devices, including hard drives/Rom Drives and put in bottom end graphics card.
So you should have, 1 stick of ram, CPU, low end graphics and PSU.
Run Windows XP, from USB flash drive with a DPC testing program on it, with some music etc to do some testing.
Then play around while using the DPC program to monitor the latency.
Spikes still occur on my UD7.
Here is my PC during that test, at it's worse.

Yikes, that's really bad. Mine is nowhere like that, I only get 1 red bar every once in a while, sometimes 2 in a row.
Have you turned off the power saving features, C1E and EIST?
Do you have much programs installed?
These are things to consider, as they might cause your severe spikes.
-
Yeah that is VERY VERY bad.
I am getting around 120 currently, very stable, on my old Q8200 I would have regular spiked around 1000, but sheesh nothing like your stuff, that is off the scale.
I will have to do some research, it isn't something I have looked into all that closely.
Oh do you have that link where they claim the motherboard could at issue? I would like to see the reasoning behind it.
-
Well I have just been testing my board GA-X58A-UD7 and running several open browser windows, email and a video as well as all the usual background programs it doesn't even top 100. So you must have some serious stuff going on there. ???

^^^ Well that tends to indicate there is no global issue, which I presumed.
Might be worth clean install Win + checking latency.
-
Just done an extended test with Media Player, 3D Vantage and a streaming internet video all running at once and still no figures above 100. Been runnning about 30 minutes.
-
Yeh I ran that test on my crusty ol'e X48-DQ6 win 7 64 Ultimate and I got about 4 spikes above 4000 :-( Anyhoo I have no issues with anything that I do so it's no probs for me. Just more garbage to fret and waste time over LOL.
-
Just a shot in the dark - but try changing your CPU Clock Skew to 900 mV under BIOS (default is 800, according to the manual.)
That fixed a few issues for me.

Actually made things worse for me :-( But I am not worried about this test. Like I said before, I can do everything without any probs. So nothing to stress over..........Now back to Bios
-
I have the same problem with my X58A-UD3R. Our values are almost exactly the same as well. I just got done trying a clean install on a spare hard drive. I am currently using Win 7 64 bit and experiencing this problem. I tried a test install with Vista 64 bit, just as an experiment. It does not matter which OS I install, I get these spikes either way. It will stay spiked for an extended time and then it might just go back to normal. It does this randomly at any given time. I attached a screen shot of my readings. I believe this to be a problem with the motherboard, as proof by my testing with fresh installs of operating systems.
-
I just found out exactly when mine spikes. It is 100% correlated to the temperature LED's on the motherboard. When the north bridge LED is off (normal), then my DPC latency is normal. As soon as the north bridge LED begins to flash green (higher temps), then the DPC latency spikes and remains spiked until the LED stops flashing again. I am glad I found the direct culprit as to why this is happening. It is not a driver issue at all, it is a temperature issue. Now maybe I can figure out how to mount a fan on the north bridge heat sink. It is quite warm here in south Florida summer and I do have the system overclocked.
-
Interesting... I ran this DPC latency checker, and got a latency spike every 60 seconds - just one bar's worth of a spike.
Coincidentally, my Easy tune is set to update itself every 60 seconds. If I close Easy Tune, the DPC spikes go away.
Not sure if this actually affects anything; I leave Easytune running because I use it to control my PWM fan, but... maybe I'll run some benchmarks and see if there is actually any negative effects to the DPC spike.

Interesting and a great find, as you issue seems to be exact same as me.
So if this is the case, how do we fix this issue?
My PC temps are quite good, 29°c Mainboard temp, 32-33°c Core temp. graphics cards keep cool as well. 2 x 5850's 46-47°c Idle.
So air flow is good in deed.
What bios version you using?

What bios version you using?
I have a rev 2.0 board with the first release bios (FA).
I have good temps as well, but maybe we need to install an active fan to cool the north bridge heat sink. I have a Corsair H50 cpu cooler, so there is space to mount a north bridge fan. The trick will be finding a way to attach the fan. Maybe have to make a bracket or something.
It seems to me that it is a fault in bios programming. When there is an LED indication of elevated temp, the latency freaks out and spikes with a huge delay. I don't know if this is Gigabyte's way of reducing temps, but it cripples the machine.

For those who are curious, the sporadic DPC latency spike caused by EasyTune doesn't appear to have an effect on gaming benchmarks.
As far as the temp-related DPCs - it is possible it is the temps causing the high DPCs, and not the LED indicators. Hard to tell which is the real problem. Personally I'm using an EK full-cover MB block for cooling the MB, but this is understandbly a lot to do for MB cooling.
-
Well the updates are very interesting. At least there is significant headway being made. Now if you all move to the nice cool UK there shouldn't be a problem any more ;D
On a more serious note my board is watercooled but not by a complete mb block just the cpu, nb,gfx, etc and even though my southbridge gets fairly warm at times I don't seem to have this problem.
I have always recommended against installing these Gigabyte programs such as Easy Tunes etc because they are not well written in my view. They are more of a quick fix(or not). You can't rely on them.

I agree on not installing the utilities. I install it temporarily for monitoring purposes. I would never use it for making changes to the system however. I do it all in the bios directly. Easy tune has since been uninstalled on my system.
-
Well I was using EasyTune to fine-tune my PWM fan connected to the CPU fan header, but now I'm either just not going to bother or use Speedfan.
Just out of curiosity, I installed Dynamic Energy Saver and played around with it, and that program also causes DPC latency spikes when you are adjusting settings or when it turns off phases for power savings.
-
This is the sort of problem that they make, best just not to install them.
-
Speedfan works fine for adjusting the CPU fan speed, so if anyone wants an alternative, I'd recommend that.
-
Quite, there are numerous third party programs out there that will do the job better in most cases.
-
I'll also pipe up on this issue.
X58-UDR3 Rev 2.0 and I'm spiking the same as you. Contacted Gigabyte who kindly gave me a beta bios for the wrong revision of board....
In my case I've noticed it when theres a fair bit of disk IO happening. Start a game and it'll sound like popcorn till it's all loaded into RAM.
Rather frustrating - even bought a standalone soundcard to try eliminate it to no avail.
-
GA-X58A-UD7 (Rev.2.0) also coming soon.Here is Manual (http://download.gigabyte.us/FileList/Manual/mb_manual_ga-x58a-ud7_v.2.0_e.pdf) and first BIOS (http://download.gigabyte.us/FileList/BIOS/mb_bios_ga-x58a-ud7_v.2.0_fa.exe) already released. ;D
-
Thanks for that ex58, very interesting, just a shame that I have just RMAd my board and received another v1 as replacement. :'(
-
Woot, I worked out one thing that can make the DPC rise!
Playing FLAC files, uncompressed music, epic fail on this motherboard, yet I have no issues playing FLAC with my ASUS.
More confused now, how is there a difference?
-
I can understand that having to decompress a complicated file could have an effect on the latency but why it should effect one motherboard as opposed to another is difficult to understand.
-
Beats me, I have been playing that particular FLAC album for god knows how long, way before I got this board, yet the issue has been ever since I got this board.
It MAY be coincidence. Going to take some testing. However I still do get the odd DPC spike with no FLAC files running, which I still can not reproduce no matter what I try, seems to be random.
-
eastley, try watching the temperature LED's on the motherboard while running DPC latency tester on your screen. Do this at night when it is dark in the room so that the LED's on the motherboard are easily seen. Put some load on your computer (playing FLAC files). The north bridge temp or the cpu temp can cause latency. As soon as either one of them reach a certain point (the temp LED on the board illuminates), the latency hits. I mounted an active fan over my north bridge heatsink and the problem has disappeared.
-
Well that would fit with my observations. My latency readings are always low and I can't get them to rise but my Northbridge is watercooled along with the rest of my motherboard.
-
Today,I got a new GA-X58A-UD7(REV:1.0) beta BIOS from GigaByte(ver:F7s). The DPC Latency's problem can be solved by the BIOS file.
The BIOS file has solved the BUG that motherboard's TEMP LED of CPU and Northbridge when they change with DPC latency time increased.
it's a beta bios, so just could solve the DPC Latency BUG only.
-
That's a good step forward for anyone suffering from that problem, as I say it's not something that affected me but I can understand that it would have atremendous impact on some people. Let's just hope the BIOS is stable and doesn't cause any other bugs.

Going to try this now.
Got massive issues tonight, heat building up, heater on. Have to take the front of the case off, let more air get in there to stop it.
Case is well air'd as it is, temps are fine with front on, just needs to be cooler.
-
What exactly are you trying to say? That the ambient room temperature is too high?

Which fan did you get for your northbridge? I am having the same problem with my GA-X58A-UD3R rev2 board when it hits a certain temperature after long periods of gaming/load and it's driving me insane. I've got a support ticket in with Gigabyte but it's not been answered yet.
Maybe we'll get a BIOS update or something out of it.

That is what you said in your post. It sounded like the room was too hot that's what prompted me to ask about the ambient temperature.
What about putting a dedicated fan on the Northbridge to cool it?
-

It is not very hot in the room my computer is in, and I actually bought a new case with better airflow, which helps a lot, but the northbridge still gets hot and causes the DPC latency to shoot through the roof, around 30,000 until it cools back down, then it runs normally, where it sits around 100-120 for DPC latency.
What fan would you recommend?
-
More or less any small fan would do to just keep the temperture of the nothbridge down. Fixing it down would be the difficult bit so look for one that isn't going to be much trouble to fit. I take it that you have already fitted the "Silent Heatpipe Module" that is supplied to cool the Northbridge and used heatsink paste?

The northbridge heatsink was pre-installed. I'll probably wait for buzzard's reply so I know what he used, unless I get an updated response from Gigabyte on my support ticket with a fix.
-
Sorry my mistake, because you posted in the UD7 thread I was assuming that is what you had but i now see that you have a UD3. That doesn't come with the heatpipe module. Looking at the picture of your motherboard it shouldn't be difficult to fix a fan to the Northbridge heatsink.

I used a Masscool 80mm fan. I have a handful of them around so it was no big deal. I used a 90 degree bracket I had laying around and attached it to the rear fan mounting hole. I attached a few pictures so you can see. No, the fan does not hit the video card. I have about 1mm of clearance lol.
-
Thanks for the pictures. I'll have to tinker with it myself, as I have a sound card in the PCI-E 1x slot just above the video card.
Either way, the board should not have problems with stock voltages/etc. I'm hoping we get a fix from Gigabyte soon, as I get really irritated while gaming when the sound starts popping and the DPC latency spikes.

That must keep the chip nice and cool, as you say if you had plenty of them why not make use of one. I think something much smaller would have done the job just as well though and could have been mounted directly off the heatsink. ;)
-

Yes the heat did build up a little but it was not that warm, the CPU was in low 30's. Ambient was 18°c, with system temps around 30°c.
That is not hot at all.
System temp right now is 25°c with Ambient of 14°c.
That is not hot, there is no way this issue should occur when temps are well within operating temperatures.
-

No I quite agree. At least you seem to have it under control now though. The UD7 and UD9 cool the northbridge with a special accessory that bolts on top of the northbridge and acts like a heatsink. It has heatpipes that help disperse the heat to the outside of the case.
-
Does anyone have a good contact within Gigabyte? I've been trying to talk to tech support but they've been pretty useless so far. I've been asked two times now if any overclocking was applied, which means a day was wasted... and my latest response is this.
"The Heatsink on the board should be sufficient enough to cool off the NB which has been tested. Unless the heatsink you have is loose or is not fully intact to the board."
Gotta love when no solutions are offered.
-
You could try to pm runn3R as he is Gigabyte's official man on htis forum however he is very busy himself and may take a while to reply.
-
I would just like to report that I downloaded and installed the new Gigabyte program for overclocking called CloudOC. By default it installs to run automatically at startup. Now I noticed that when this program is running my latency is sky high and normally nothing will move it from the bottom. So just a word of warning for anyone who is thinking of installing it.
-
Yeah, I did read on some forums that the Gigabyte programs to overclock/regulate/etc cause problems, but I never installed any of the programs, just the basic drivers.
-
This is the best practice with most motherboard included programs I find. Just install what you are going to need form the internet. You also know that they are right up to date then. Same with drivers.
-
Hi,
I have exactly the same probleme, same graph as eastley. I have a GA-X58A-UD5 and i use an additionnal sound card (Auzen Xplosion)
it happend when i play musique/vidéo or when i play game.
Is Someone have already use Windows Performance Toolkit and xperf to identify the problem ?
My northbridge is at 75°C after 1 hour of playing, i will try to fan it
my config
X58a-UD5/i7 930/Gskill@2Ghz/Xplosion
-
Your northbridge temperature is a bit high and could do with some cooling for a start. What case and cooling do you have? Also can you list your components and your actual problem as you see it?
-
hey :)
I have a thermaltake kandalf Case with a 20cm Fan on the side
I use a H50 too (only one Fan on it)
When the probleme comes, the sound crackling. Pb during around 5min, dpcs are up to 28000µs and after the Dpcs going down.
I tried to disable some device with no luck :(
Very annoying pb.
-
First thing is which way is your fan blowing on the H50? If it is into the case reverse it so that it blows out. I know this is contrary to popular belief but it can make several degrees difference in your case. What other fans do you have?
As far as thge sound problems go ahve you tried cutting out all the background programs that are loaded automatically on startup? I know it's a pain to sort through them but chances are it is the problem. The only other thing is to check your cables and make sure that data cables are not run near power cables if possible. Can you move the sound card to another slot?
-
i have two fan on the rear, both inject the air in the case. I have one Fan in front wich is extracting the air.
It happen on an fresh install, i have only three drivers installed :
chipset intel 9.6.0.1014
Catalyst 10.6 and latest Crosfire Profile (i have HD5970)
and the sound driver, no whql version but works great on my other motherboard EP45-UD3P
No program in background, just i launch MediaPlayer classic, watching an episode of simpson and the pb occur :(
edit: only one PCI slot on this board :)
-
what do you mean by pb exactly?
-
sorry im french pb means problem :) (the sound crackling and a huge DPC latency)
-
Thanks for clarifying that. Normally the problems occur when either the northbridge is too hot or there is some other program in the background that is conflicting. As an example I downloaded CloudOC and ran that, now I never have any problems with latency at all, but suddenly my readings hit the roof. As soon as I killed the progream they returned to normal. It was set to load at startup and it wasn't untill I went through what was running in Task Manager that I found it. I would suggest looking to see if you can find anything.
-
yes, i try to install DES ET6, it appear some DPC latency when i use it but return to normal when i close it.
it's really the same graph as eastley, a huge dpc latency sometimes and return to normal.
i will try this evening to arrange my sata/power cable in the case, and put an additionnal fan on my graphic card which cooling the NB
in any case, thank you for your help :)
Is eastley found a solution for that ?
-
I haven't any more information than what has been posted in this thread. Anyway let us know how you get on.
-
ok thanks, ill be back for the great news (hoping)
-
Hi,
I think i found it.. It seems to be the NB and ICH10 chip wich are too hot.
-
Good, well not good but at least you have an answer to your problem. Now it is just a case of finding the best fix for it.
-
for low cost -> replace the intel stock fan :(
-
for low cost -> replace the intel stock fan :(
Ok so far as it goes but it isn't going to impact the temperatures on the North and South bridges a great deal.
-
the intel stock fan is apparently able to ventilate de NB. On another post, a guy have the intel fan, and he have 48°C on the NB against 75°C for me.
the ICH Chip is just connected by a caleoduc. If the NB is not ventilate, the ICH Chip is very hot (add 10°C) so 85°C for me.
-
Whilst I would agree that the choice of fan has a bearing on the Northbridge temperature(Some fan/heatsink assemblies being higher than others) I wouldn't have expected such a difference in temperature. As far as the ICH10 chip goes thta is too far away form the processor to be affected by nay CPU cooler. In fairness the Southbridge is not usually subject to so much heat anyway. It is easy enough to make up a bracket to hold a small dedicated fan over the Northbridge anyway.
-
According to this guy, i put a temp probe near the NB and near the ICH Chip. Temp measured are around 5°C lower than HWMonitor show up.
And the ICH is warmer than the NB.
In addition, ICH Chip is just below my 5970 that is very hot (85-95°C)

je refais la meme chose mais la sonde sous le radiateur de l ICH10 et j'ai pratiquement 10 degrés de plus que précédemment , ce qui voudrait bien dire que l ICH est bien a une température plus élevée que le X58

Thanks for the translation(you know how crap we Brits are at other languages ;)). I can't say I am surprised at your findings, the software temperature readings are often unreliable so a difference of 5 degrees is not unusual. As you said your southbridge chip is probably warmer because of its proximity to your hot graphics card. A lot will depend on the amount and type of use it is getting at the time.

Hey guys,
I've been fiddling with this one all night, but have finally figured out a temporary fix:
Here are my specs:
Win7 x64
Intel i7 930 processor
Gigabyte X58A-UD7 motherboard
EVGA GeForce 460GTX video
I found that the combination of disabling the CPU Enhanced Halt (C1E) and Adjusting my power plan (within power options) in Windows 7 to "High Performance" solved the problem on my end. Before this, i was experiencing (almost steady) DPC latency's that were > 16000us when playing audio from my computer (resulting in a static/crackle noise). After the above changes I'm averaging around ~120us with no audio crackling or side effects.
Finding the C1E setting may be tricky in the bios:
M.I.T Intelligent Tweaker -> Advanced Frequency Settings -> Advanced CPU Core Settings -> CPU Enhanced Halt (C1E) [Disabled]
I hope this works on your end as well! :)

Thanks for sharing this information with the forum, it may well save someone else a lot of time trying out different settings. ;)

Hi there,
im back !!
The new beta bios (fb10) for the GA-EX58-UD5 rev2 has fixed the issue for me. No DPC latency and no audio crackling.
See ya
-
Another member that it has worked for. Great!
-
Hello,
I also noticed the high latency with my UD7 board.
I would like to try the new bios but i dont know which revision it is.
cpu-z says "rev 1.3" , but there is no 1.3 for the UD7, is it?
thanks
-
Check on the bottom left hand side of the motherboard, it will be printed in white lettering just under the expansion slots.
It may not be fixed by a BIOS update though, it could be a program running in the background that is causing it.
-
thanks.
i could not reproduce the spikes ... it just happens .
i was playing sc2 2 hrs, everything fine
i streamed video , was ok
i played a 1080p video , all ok
i run a gpu benchmark , all ok
then 3minutes later, system idle , the latency was up again for a couple of minutes, then all back to normal
happens sometimes during a game (metro2033, sc2) or internet stream, but i dont think it's NB-heat related, because during the stress test it ran fine.
that's why i want to try the bios
-
Well let's hope the BIOS update does indeed fix it for you as it has for many others. If not try checking the programs that are set to run during idle.
-
Are you sure it's not the video card (gtx 460) that's causing it ? I just got the GTX 460 1GIG version and am getting these DPC spikes.
More info here @ http://www.evga.com/forums/tm.aspx?high=&m=508637
my system:
intel q6600
8gigs ddr2 800mhz ram
XFX 9300m
NVIDIA gtx 460
Windows 7 64bit
-
It's quite possible for any of the drivers to cause latency problems if they are badly written. It's all to do with how the driver accesses the kernal.

Hello,
Who have test the FB Bios ?
here for the rev 2.0 http://www.gigabyte.fr/products/product-page.aspx?pid=3450&dl=1#bios
-
I have the rev 1.0 board and have run most of the BIOSes that have been released for it. The latest update is very similar to the one that you are enquiring about I think so it is probably just a port of that to the rev 2.0 board.
-
hey :)
Ok, but i do not want to return to the same problem : the DPC Latency on the FA BIOS
-
Well if the Beta BIOS update FB10 worked for you there is no reason to think that the final release of it is going to be any worse. If you are in any doubt though why run it at all. Assuming that your current setup is stable stick with that.
-
OK i will test it. yes my setup is stable with the FB10 Bios.
Only one thing, i have 2 fans on my H50, and when the computer is booting, the second fan is not at 100%, i have to run Speedfan to solve that.
-
To be fair it really doesn't matter if neither of your fans were working at all on booting. As long as the pump is working the cool water in the system would keep the temperature down for at least several minutes just in passive mode.
-
Yes, its not really a issue. But this fan stay at 800 RPM instead of 1350 RPM. The Processor is overcloked so when i lunch a game, i run speedfan before.
One of these fan is plug on the first 4 Pin connector : CPU_FAN, the other on the second 4 Pin connector he's called SYS_FAN2.
-
Both the CPU fan and SYS Fan2 can be controlled by the BIOS because they are both 4 pin PWM fan outlets.
-
Yes. But in the BIOS i have a setting for CPU_FAN control. I have disabled this for manual control. There is no setting for the manual control of SYS_FAN2
-
CPU Smart FAN Control
Enables or disables the CPU fan speed control function. Enabled allows the CPU fan to run at different speed according to the CPU temperature. You can adjust the fan speed with EasyTune based on system requirements. If disabled, the CPU fan runs at full speed. (Default: Enabled)
You are quite correct that there is no way to control the SYSFAN2 from the BIOS. Stupid really.
-
yep :(
And in speedfan there is no fan that it can control. Other Fan are not listed.
Same with FB BIOS..
-
Hi, I found this article while googling. I believe I have the same, if not a similar issue. Here is a synopsis.
So I have a really, really annoying problem with my rig in regards to sound.
X58-UD3R
i920 @ 2.8ghz
6gb Corsair Dominator RAM (1336 I believe or around about)
GTX480
X-Fi Titanium Fatality
Win7 64bit
The breakdown.
In the following games the problem occurs after 6-10 minutes of playtime.
-Civ V
-Napoleon TW
-BFBC2
-Sims 3
-Dirt 2
-Mafia II
-Medal of Honor (2010)
-Just Cause 2
Unaffected Games
-Guild Wars
-Dead Rising 2
Minimally Affected Games
-CoD Black Ops MP (nuketown with 32 people spamming nades)
-Team Fortress 2 (DPC shows a spike but I dont hear any change to audio quality)
-Far Cry 2 (Comes and goes during heavy explosions)
-Lost Planet 2 (some snap crackle and pop during brief moments but doesn't last)
The problem?
After 6-10 mins of playing most games my crystal clear audio begins to pop and crackle. If I was sitting in the jungle all by myself and this occurs I can hear soft pops. The second a boom or explosion occurs you can really hear the pop and crackles much louder.
So in a game like BC2's nade spam fest I hear a tonne of loud popping and crackling after 6 mins of crystal clear gameplay. Civ V also pops and crackles, the louder the sound the greater the audio distortion.
Games like Guild Wars however remain 100% unaffected, after hours of straight play there is no popping or crackling, even running Guild Wars and WMP playing heavy metal thrash.
I don't notice any cracking or popping in Black Ops SP, in MP I can only notice a little when 32 players are only spamming grenades and there's explosions everywhere.
The audio pop and crackle problem once it begins stays until I exit the application, click refresh on my desktop and give it around 20 seconds. If I exit the application and immediately play music, that music also pops and crackles with distortion. If I exit the app, wait 20 secs and then play music, the music is fine.
When did this begin?
Truthfully I am not sure, I noticed it with the release of Civ 5, and then weeks later when I played BFBC2 and my PC was a fresh install and clean build done in late sep.
It's your soundcard?
Is it? I am aware my card has reported issues with popping and cracking, I have researched this and I am not suffering the same issue. The X-Fi pop and crackle problem is that the audio is crap 24/7, moving the mouse makes horrible noise, etc. Mine is only for applications which actually make my PC work hard.
So then your soundcard is broken?
No it is not. I have disabled my X-Fi and used onboard sound. The problem persists but is less obvious and less annoying, only due to the fact the onboard soundcard isn't as powerful as the X-Fi. I have also physically removed my X-Fi and used only my onboard sound and the problem remains.
Drivers dude?
Updated them already, and them scrubbed them with driver sweeper and tried all sorts of variants, the problem remains. Perhaps a format and a clean install might work?
Fiddle with your settings.
Done that, I have tried every fix that the X-Fi problem FAQ recommends, Audio creation mode, 24bit matched playback, disable crystalizer etc. They all do nothing, also those are fixes for the X-Fi. Uninstalling and scrubbing all the X-Fi drivers and physically removing the card and using purely the onboard audio still gives me the same problem. Disabling onboard sound and using my X-Fi also gives this audio problem.
Well what the hell?
I downloaded a DPC latency checker and when my audio pops and crackles in games after 6-10 mins you can see the bars jump up to 2800us+. Something IS messing with my rig. During the heavy pops and crackles with BFBC2 I ctrl alt del and check on my memory useage and CPU, they are both pretty good with plenty of leg room. I would assume then this is related to my GPU?
Possibly related? My computer has blue screened around 4-5 times suddenly since it was built and clean installed in september. Error message was a physical memory dump.
Do any of you have any other ideas of how I can troubleshoot or fix this audio problem?
When I got my PC games like Mafia 2, Dirt 2, Lost Planet 2 and Medal of Honor worked fine with crystal clear audio. But now these games suffer from the audio pop and crackle problem, some more than others. Perhaps the latest nvidia drivers did this? the 260.99 version?
I scrubbed them off with drive sweeper and installed my default nvidia drivers off the disc, they are 197.41 but the problem remains. Although as mentioned when I first got my PC Mafia 2, Dirt 2 etc all ran brilliantly with good audio, now, no matter what drivers I put on, it's a snap crackle and pop fest in a few mins of gameplay.
Ideas?

Hi and welcome to the Gigabyte Forum and Happy Christmas.
Have you disabled the onboard sound option in the BIOS?
Try moving the sound card to a different slot.
Have you been though the recommended faultfinding technique for pinning down the culprit of the latency?
-
I can't move the soundcard to a different slot as the GFX card takes up too many. Removing the card entirely and using only onboard sound still gives me high DPC latency.
I couldn't find any option to disable the onboard soundcard in the bios, in fact under the bios I noticed there was actually very few options in comparison to older mobos 0.o
I am also unaware of how I track down the exact culprit of the DPC latency loss. I tried disabling devices one by one, or shutting down services but I have had 0 success after a non stop week of troubleshooting :(
-
Hi
To disable the onmboard sound option just go to the Integrated Peripherals section in the BIOS and disable the Azalia Codec. So try that first.
With the latency issue the problem is easilly fixed but finding the culprit can be more troublesome. Latency is caused by bad programming generally. There are various
rules for how a program should access the core and if it doesn't follow these rules it can result in the core not being released for the next
operation and this causes a bottleneck that backs up. The biggest headache from our perspective is that we have to find the rogue
program/driver.
The best way to tackle this is to go to Task Manager and then in the Processes section stop all the processes that are not required
for Windows to run. If you do this one at a time until you find the one that is causing the trouble. Then depending on what it is as to how you
tackle the repair.
If none of that works you would need to go to Device Manager and disable all the devices not needed to run the system. Then you can
enable them one at a time and again see which one causes the problem.
Have fun!
-
I have been tinkering and here are some updates.
I disabled the onboard sound (it being called Azalia Codec instead of Realtek Audio etc threw me off a little)
And disabling the onboard audio does not fix the problem sadly.
But perhaps I am getting closer.
I noticed with the DPC checker on when I plugged in my LAN couple there was quite a spike, within the yellow zone, but tolerable.
So I fired up Civ V which is a game where I can reaaally noticed this issue. And after a few mins the audio popped and crackled. I went to device manager and began disabling devices, and waiting around 20 seconds before re-enabling them.
When I disabled the onboard LAN connection, 7 seconds later my DPC dropped from 30,000+ to around 150. I returned to my game and played for a further 7 mins until the pops and crackles returned.
I then enabled the LAN connection again. No change. So I disabled it again. No change. :(
So I continued unabling other devices and when I disabled a seagate external HDD the DPC dropped from 29, 000+ down to around 120.
So I turned off my PC and removed the external HDD completely.
I then tried Civ V again, and sadly, the popping and crackling returned within 2 mins of gameplay.
I am however notcing that the more and more devices I disable in the system manager, that when the DPC loss occurs, it doesn't "seem" to last as long, but it's still there and it's still verrry annoying.
I'm going to back up my data tonight and then try updating the onboard LAN drivers, see how that goes. After that I will update the bios.
I have been using the task manager to look at processes when the DPC loss occurs and none are using more resources than they should. I also can't noticed anything else running that shouldn't be. I have turned off a tonne of processes, but the DPC loss still occurs.
The search continues :(
-
It casn take a while to hunt it down to be fair, but I think you are attacking it from the wrong direction. I would suggest turning off/disabling everything that isn't need to run Windows and the try playing your game and see if you still have a problem. If you do then it is more likely hardware based, although this is more unusual.
If it runs fine then, you can start enabling devices one at a time until it returns.
-
News from the frontlines...
I backed up all my data to my ext HDD in case what I did next went wrong or my only solution was a format.
What I did.
Disabled pretty much eveerrrything in device manager and restarted my PC. The issue still occurred, just it took longer to occur.
Sad face :(
So then I downloaded a bios update for my X-58A-UD3R rev 2.0 mobo. I was using the FA rev 2.0 now I am using the FC rev 2.0
It's still early days, but so far I have not heard any audio pops or crackles from microstutter. I played Civ V for a little over an hour with no pops or crackles and 0 microstutter. And when I quit I noticed I had reached 29k+ in DPC latency but I never noticed or heard it.
I then played BFBC2 and played around 3-4 full rounds. Again I didn't notice any microstutter or hear any pops or crackles. But when I quit the game I did see one red spike and DPC checker said I did have a max of 29k.
So the problem it seems is still potentially there, with me having insanely high DPC loss. But I cannot notice it yet in games. And if this continues I could live with it. I didn't notice stutter or hear the annoying pops and crackles, but the DPC checker says there is still some DPC loss.
If I had to guess what was the cause of all this, I would point to either SATA 3 or perhaps USB 3.0
I will keep you updated if this problem returns or I notice it. As I said it is early days. I will also return in a few days or a week and tell you if the problem has gone away or is so minute I can't notice it any more.
-
Well at least you seem to be making some headway now and I am sure that you will get there in time ;)
-
Okay, so the mobo bios update has reduced the DPC latency loss considerably. It still spikes from time to time, but it doesn't give me that audio popping/crackling problem any more.
Maybe the occasional one or two pops now and then, but nothing like what it was doing. So to users experiencing similar problems, I recommend updating your motherboard bios.
-
Yes I would agree especially if the BIOS version you have presently is an older one. Often little things like this are fixed in the updates but don't make it onto the description list of fixes.
