Having a few problems with my new build (2500k).
When i have the power saving features enabled and overclocked to 4.6Ghz, after i resume from sleep the cpu speed is stuck at 1600mhz. I cannot get it to ramp up again to full speed.
Now after disabling all the power saving features, when i resume from sleep i notice that core 3 fails after a few seconds of prime 95. Is fine from boot, but after resume from sleep it fails really fast.
Anyone have the same problem>
-
Hi
I have a similar board the UD5 and haven't noticed the problem but then again I always have the power saving turned off and don't use sleep mode often. I will look into it tomorrow if I get the chance. ;)
-
It appears after observing the voltages readings on HW monitor, that when i resume from sleep the voltages run at their stock settings (not overclock), which i imagine are to blame for the prime95 test to fail. Hopefully this will be resolved with a bios update.
-
That does indeed sound feasible. For now it should be possible to switch the speed back to standard to give you stable performance across the board.
-
For now i am avoiding the problem by not using the sleep function. This is pretty annoying as i would have the computer in sleep mode alot. I have submitted the problem to tech support to hopefully the issue will be sorted in a bios update. A quick google search shows im not the only one with this problem.
-
Please post again when you get a reply.

This is probably caused by CPU PLL Overvoltages, this is disabled on resume from S3 so you probably can't reach the same multiplier as you could with it enabled before you put the system to sleep.
I am not sure if they will be able to fix this, or if it's an Intel Microcode fault? It's been a known issue for a while, so it may be something they cannot address.
-
I did a test with disabling the CPU PLL Overvoltages in the bios, but no change.
Thanks for the ideas, really hope this gets sorted.
-
I don't think disabling it will help your case anyway. If anything it needs to be enabled all the time to compensate but I don't know of a way to ensure that after sleep.
-
Two things, first is your system 100% tested stable as you have it? You must be 100% stable for S3 to even work
And second, disable CPU PLL Overvoltage is not going to help, this will cause your overclock to fail. What I meant was since this gets disabled on resume from S3, you will need to use a lower CPU multiplier (Where you don't need CPU PLL Over), that way on resume from S3 it wont matter that the CPU PLL Overvolt has been disabled.
Some CPU's can do 42-45ish without it, others can do 46-50+ without it, you will just have to find the stable limit of your CPU without this setting enabled if you absolutely need S3 sleep for now.
-
Ok so i am pretty certain i am 100% stable at 4.6Ghz, prime 95 for a good few hrs.
After about an hr of testing with different voltages and multipliers in the bios it looks like pretty much any adjustment to the voltages will reuslt in the sleep function being unstable. Stock has been tested and is fine, but anything else i cant resume at anything other that 1600mhz from sleep.
Such a pain as my system would be in sleep state most of the day usually.
-
I know it isn't perfect but can't you run your memory at 1600 if that is stable as the speed difference is negligable unless you are benching ?
-
Its not my memory speed thats the issue, its the CPU. And to run the CPU at 1600mhz is a bit low :)
Anyways i tried downclockin the RAM and the voltage of RAM to make sure it wasnt the problem, but again, no luck, cpu locks at 1600mhz upon resume
-
How high can you overclock the CPU without CPU PLL Overvoltage, what multiplier?
-
Ok i have ran a more tests and come up with the following.
With PLL voltage enabled, i resume from sleep at CPU 1600 mhz if any overclocks applied
With PLL voltage disalbed i can run at stock speed, but voltage up as high as 1.37 and all normal
if i put the cpu speed up a bit say to 3.6ghz, fail
with Pll voltage disabled the system refuses to resume at anything above stock multipliers, just a black screen after i hit the power button.
at least with PLL enabled i can get into windows abiet at a CPU speed of 1600mhz
-
Then it could be BIOS is not S3 sleep capable yet? Or this could be due to you using speedstep since you keep mentioning 1600Mhz, when you say that you mean CPU speed right?
What BIOS are you using? I can test S3 Sleep on UD4 tonight, but I'll use the latest BIOS
I can test B2 or B3 BIOSes, let me know which you want tested.
-
bump
Just to see if anyone else is having the problem. I am still unable to find a solution and am trying with Gigabyte tech support to work out whats wrong.
-
I am using Bios F3. If you could test that would be great.
-
Anyone come across anymore information regardin this issue? I have been back and forth with gigabyte but they are saying they are not experienceing the same problem.
Im at my wits end with this one. My CPU voltage always drops to 1.28 after i resume from sleep, regardless of what setting i have.
Is your UD4 doing the same? Or should i think of RMA?
-
I will test tomorrow for you.
Please tell me what voltages you need me to test above, and what CPU/memory speeds and timings you want me to test with. And for how long should I let the system sleep?
I will be using this BIOS, since I have my UD4 flash over to B3 now, so if you have a B2 board you should RMA it for B3 or flash over to B3 BIOSes
http://www.mediafire.com/download.php?xt1wl8l5hciqdsz
If you need to flash over to B3 BIOSes, you'll have to use this modified BIOS and flash with @BIOS, then use ALT + F12 once you get it all going, to flash the backup BIOS to match and be a B3 BIOS as well. Then once you get to both BIOSes on B3, flash the above linked BIOS with Qflash, and then again do the ALT+F12 to match the backup BIOS.

Hi there,
Thanks for testing this.
I am using a B3 board with a 2500K. F3 biosfrom the Gigabyte site (i have used the modded ones but same problems)
I have everything at stock. Then apply a 46X multiplier, CPU voltage of 1.36, and memory XMP profile. Regardless if the CE1 powersaving features are off/on the problems still persits. S3 sleep enabled in the bios.
Boot to windows and open HW monitor to see the voltages. Run an test of Prime95 to see its fully stable and the CPU voltage hovers around 1.36 as it should.
Put the system to sleep for any matter of time, even seconds. At this point when i run Pime95 a core instantly fails and when i look at HW monitor my CPU voltage has dropped to 1.28.
I have tried so much to get round this. If i up the voltage in the bios to 1.4, it still drops to 1.28. If i drop the multiplier to 40, still reverts to 1.28 voltage.
I am basically stuck from going any higher that 1.28 voltage if i use the sleep function.
I am so frustrated with this and its the only thing wrong with my near perfect new build.
I would actually pay someone if they provided a fix for this, its that annoying!
Thanks for any help

I wouldn't say things like that on this forum with all us poor people on here. You are likely to get stampeded in the rush! :o
-
Getting somewhere with this tonight.
I notice that when i disable LLC in the BIOS and boot with a 46 multiplier and 1.36v the voltage readout in HWmonitor drops to 1.28 as soon as i run Prime 95, and a core fails instantly. With LLC enabled all it fine.
Until i resume from Sleep!
And exactly that same happens as if i disabled LLC. So is it possible that LLC is not being re enabled after i resume from sleep??
-
Ok, since we don't have the same ram or boards, I'll just test the latest B3 BIOS that I've modified here and test at x46-x48 just to be sure
http://www.mediafire.com/download.php?xt1wl8l5hciqdsz
Are you using CPU PLL Overvoltage to get your x46 CPU multi? If so, that is the problem as I don't think they've figured that out yet, on resume this gets disabled and I think it's something they are waiting on Intel to fix.
-
Ok, you are correct!
I tested at 4.6 using 1.44 BIOS set Vcore, 1.428 idle and 1.416 load, using F4 final BIOS. Then sleep and resume and idle is 1.402, then 1.34 under Prime95 load, no crashes here but that's probably because I set the vcore pretty high to start out with because I have not played with this CPU/BIOS for a while and never at 4.6 so I wasn't sure what I'd need.
Please send in a report here, and I'll see if I can have them look into it as well

Hi there,
Thanks very much for helping me out and testing this. I already have a support conversation started email ID 1080751.
I have not been using PPL overvoltage.
If i dont use LLC i am unstable at high overclocks. With it enabled, all fine, until i sleep..
Would be great to have this resolved.
Thanks
-
No problem, I'm always happy to help and test for users when I can!
I sent in an issue report on this tonight asking if the BIOS guys could look into and test on this issue, so I'll keep you posted once I hear back from them.
Ya, I didn't use CPU PLL Overvoltage either, don't need it until about x48 or above CPU multi. I always use LLC , so my testing was done with LLC enabled. This can be worked around in the current BIOSes, but you'd have to use a very high and unnecessary Vcore to overcome the large droop under load after a resume, and that's not ideal at all.
I'm sure they can probably fix it, they just will need some time to test and adjust the BIOS most likely.
I'll keep you posted!
-
OK, have a small update for you kinda.
I've been testing and talking with the guys are Gigabyte on this for the past few days, they are unable to reproduce and I've even sent them images of my BIOS settings where I could, so not sure what the problem is. They've showed me several test results at various settings before and after resume and everything looks fine.
So hard to narrow down I'd say, and it's not looking to be a BIOS issue...
So they would like to know for now if you've sent in your full system hardware details to the tech support team your speaking with at GTS?
-
Hi again,
The guy from GTS has requested a full report on the issue, so am in the process of compiling screenshots / list of setting and will hopefully submit all this later tonight. I heard mutterings over on some other forums regarding PSU compatibility, could this be the case? I have an 850W Collermaster. Or more likely a BIOS issue.
Anyways i shall submit all the details and let you know.
Thanks again
-
Hi there,
I emailed the requested report to GTS, subject line
1073855 - GA-P67A-UD4-B3
please let us know any developments
thanks very much
-
Thanks, I'll keep you posted once I hear back again.
I don't think it's a PSU issue, no way both of our setups could be affected by the same PSU Incompatibility in the same way? I'm using Ultra X3 850W, but could test with Hale90 750W too, but I don't think a test like that is needed really.
They say and show me it's working fine for them, so it can't be a BIOS issue. I guess that means something in our hardware is the same and causing an isssue, or both of our boards are faulty in the same manner maybe, not sure at all man? I'll keep you posted though once I hear something back on this.
I sent in images of my test BIOS settings as well, and idle/load images showing temps with real temp cause they thought maybe temp issue or throttling, CPU-z x 3, easytune advanced voltage tab - for both before and after resume.
I use the following, and it sounds like the only hardware we have in common is the BIOS as I'm actually using a B2 board even.

Hi,
Is there any update on the whole sleep issue?
Anyone with the same problem had any luck?
-
SUCCESS!!
Gigabyte sent me the F5b BIOS which has sorted my sleep problem.
System now maintains CPU voltage after resuming from sleep.
Thanks to all at Gigabyte for the help.
This is why i buy Gigabyte kit!
Thanks

Glad to hear that you have finally managed to get this sorted out and I am sure that there will be others who had the same problem and will be glad to hear of a fix.
