Hi I have 2 problems a p55a-ud6 mobo..( i have the latest f11 bios)
1- I noticed that the PSU is making some screeching noise based on activity
tried turning off c1e/eist in bios... and that got rid of the screeching..
but I want c1e/eist on... so how to fix that?
2- while in game menus I hear the psu making high pitched whine sound... turning c1e/eist off does not solve that
also while recording guitar stuff with line in...I hear the same whine in the recordings..
the whole PC is brand new... and I've read that some people with GA-X58A-UD3R boards had those issues..
now for me... what can I do?
edit: also i get those random beeps from the internal speaker, many people talked about that but some of them had new bios that fixes the problem.
but I am already on the latest bios.. so how to solve this issue too?
-
I would try (if you are using a USB mouse) moving it to another port. Sometimes this helps. Failing that I would advise RMA the board. This is not a common problem on this board.
-
C1e issue is not common on this board ?
but how is it the exact issue that happens with other boards ?
also i found that other p55a boards exhibiting the same issue from searching around the net..
is that a hardware problem?

Get a new PSU.... your cheap or faulty PSU can not handle the sudden drop or increase in voltage is needed properly.

my psu is thermaltake toughpower xt 775w
its a brand new high quality psu..

Most of the boards that seem to suffer with this problem are X58 based boards, in particular the UD3s. Obviously there are exceptions to this and no doubt if you search hard enough it would be possible to find any type of board with this kind of problem. I would say that it is undoubtably a hardware problem and whilst a software fix can alleviate the symptoms(ie disable C1E etc) it is only a work around.
-
it would be a problem i think for me to RMA the board in my country...
if I sent the board, maybe with their PSU combination they won't hear the screeching sound...
I heard that some high quality PSUs are sensitive enough to the MOBO to produce this noise.. but I don't know what to believe..
while searching the internet, there seems to be pretty much people experiencing this problem, and also with different brands of boards..
it seems to be related to the P55 platform and the x58 platform...
so I don't know..
my problem, that i think that this would not be an excuse to get the board on RMA, and the worst case scenario, maybe the psu that they test the board on may not produce the noise..
thats what i read through forums... that cheaper PSUs does not produce the noise..
also hypothetically speaking, if they did exchange the board,.. I am not positive that the new Mobo won't do the same problem...
cause really, alot of people out there having the same exact problem... so I am having a hard time believing that all those mobos from different brands are faulty with the exact ill !
-
Yes, you are having the same problem as many others. As you say it is not even just Gigabyte boards there are many makes affected. The main trouble in sorting this out is that it is caused by certain factors being brought together and often if one of them is replaced it will change the outcome. I don't agree that the cheaper PSUs are without this problem though as there have been cases with cheap and expensive brands.
-
so, I don't really get it..
certain configurations produce the problem..
then, where is the fault?
If I am to replace all my hardware with new exact models... then I would get the problem again...
-
Quite possibly, but don't forget even if there isn't an actual fault everything is made to certain tolerances and if you have a couple of items both with loose tolerances they can "react" together.
-
yeah.. considering even that theory hurts my head..
but out of curiosity here,... whats the cause of this c1e issue?
for x58 users I read that there would be a bios fix for that, and read somewhere that they are doing replacements for it...
whats the story?
-
Well to cut a long story short Gigabyte thought they could just do a bodge up by issueing a BIOS update which basically just turned some of the power saving options off. As I said this was just a workaround but it did stop the noise for now. I understand that there is now a hardware fix being offered and if it applies to you then you will need to PM runn3r the Gigabyte Moderator of the forum to arrange it.
The cause of the issue is a bit complicated but in a nutshell is due to feedback frequencies in the coils.
-

Like I said your PSU maybe faulty (being that its not cheap one) not that it can't give a stable power out but due to the sudden drop or increase in voltage & current used by CPU on demand also if your AV is below 115V or not at 60Hz that can cause power regulation problems.
What you can try is to set in the BIOS > MB Intelligent Tweaker(M.I.T.) > Advanced Voltage Settings the" Load-Line Calibration" to enable.

the hardware fix seems like a replacement at least for some parts...
but I think this arrangement would be hard for me, because I am overseas, and that would cost me the mobo price lol..
but then that gets me worried if every other p55a-ud6 in our stores stock has the same issue :(
edit: does the issue with x58 boards do the noise around the cpu only, or does it transmit the noise to the psu ?

well, I have my PC connected to a UPS, I will try hocking the pc straight to the AC line to see if that would make a difference...
regarding, load line calibration.... well I have this off, because I heard that when enabled, it may cause CPU voltage spikes which could do unwanted damage..
I see the gist of why you are proposing this, but if that worked, it would still be a workaround, but much better workaround than disabling c1e, in case i didn't get a cpu spike :D
-
I haven't been able to test a board myself so all I have to go on is second hand information and what I have seen and heard on Utube etc. Most of the sound comes from the CPU area not the PSU as far as I know.

Here it seems to suggest at the bottom “In the mean time, enable LLC and enjoy the stable VCORE!” with others OC their CPU and increasing the voltage to the CPU having this LLC (Load Line Calibration ) enabled is not likely going to cause any issues.

-
After reading Peter's link there to overclockers.com I think Bob did a thorough job of testing for spikes which I might add he didn't find, so I think you are safe in enabling the setting.
-
I will test and see if it has the same effect of disabling c1e...
-
nah... LLC does not fix the issue..
sure, it should not... because those noises are accompanying the change on vcore that happens while cpu is shifting back and forth between lowest multiplier and 20x multiplier...
ie going from being stepped down to full speed and so on..
I've noticed the way EIST works... which I find weird. and don't know if it works with you like this or not..
it seems that under light loads.. the cpu is shifting to full speed, then gets stepped down, then full speed again, then stepped down... etc..
it doesn't keep a constant clock...due to changing multipliers... so that means that vcore is going up and down every second on light loads... and I think that what produces the noise...
of course thats not the case with high loads, which makes the cpu constantly full speed
I concentrated on listening to the noise closely..it pretty much seems like a hdd on activity...a bad hdd which when spins makes a little squeaky whistle
this noise is both annoying and keeping me worried on the same time...
-
There is another way that is supposed to help stop the noise and that is to fix the core voltage rather than have it on auto.
-
yeah, but that would render c1e useless...
well there is an activity that I am able to reproduce the noise with evey time i try which is just opening internet explorer and scrolling a page up and down with the mouse wheel,
it does not produce the sound If I scrolled by left clicking and holding the slide bar and sliding up/down... I have to use the wheel to reproduce the noise..
also If I have the internet explorer window in the foreground and move the mouse around it into whatever webpage displayed on it, It reproduces the noise but quieter
-
Are you using a Logitech cordless mouse? If not what are you using?
-
no, I am using a crappy standard USB mouse :/
-
i noticed why scrolling with the wheel produces the noise in the psu, and scrolling without the mouse wheel does not...
I opened CPU-Z and compared the difference while doing both things..
scrolling with the mouse wheel: makes the CPU goes to full speed from 9x multi to 20x multi.. accompanying the voltage raise
scrolling without the mouse wheel: does not raise the multiplier and the cpu stays stepped down...
also tested moving the mouse around the internet explorer web page, makes the cpu go full speed, and thus the noise..
how mouse movements supposed to raise the multiplier and make the cpu go full speed ?!
-
Well in view of what you have just posted I would suggest replacing the mouse. It could just be a faulty mouse and they are cheap enough to at least remove this possibility from the equation.
-
the mouse maybe be causeing the stepping up/down of the processor..
and this processor behavior happenes in other conditions thats not related to mouse, when I am using a pro audio editing software..
the problem is that this stepping should not produce this noise on the PSU..
I will try anyway to replace the mouse and see if there is any difference..
-
ok, changed the mouse, even used another usb port..
THE SAME PROBLEM...
its really getting under my skin..
-
well, I have my PC connected to a UPS, I will try hocking the pc straight to the AC line to see if that would make a difference...
Did you try that in the end?
-
yeah, I've just finished trying without the UPS...
the SAME Problem...
I am really getting worked up....
it seems very obvious its a Speedstep problem!...
I don't know how it supposed to work, but its pretty JUMPY... and of course VCORE jumps with it..
and that causes a noise in the PSU...
which to blame.. the PSU or the MOBO.. I don't know
and if one is blamed, I am not sure if it should be considered faulty as it may work in other configuration without the issue.
I have limited recourses to do trial and error, so I don't have any spare PSU here to try...
of course I removed from the equation the GPU... I am not sure but I don't think it has anything to do with C1e...
-
Have you tried disabling EIST inthe BIOS?
Can you just borrow a PSU from a friend to try?
-
Contact Thermaltake and see if they think its the PSU.
-
here is the power supply I use (http://www.thermaltakeusa.com/Product.aspx?C=1264&ID=1943)
currently, I have this PSU hooked to radeon hd 5870 by 2 PCI-E power cables..
and I have another 1 sata power cable that I have hooked 2 hdds to it...
and another molex power cable that have 2 12v fans hooked in it..
thats all...
the remaining 4 fans are connected to the motherboard fan headers
I don't think any of my friends would have a PSU high enough for my system.. so this could be a problem...
I will try to contact thermaltake... but I know the response already :)
I meant by EIST, the accompanying VCORE changes with it, and of course its related to C1E..
as of course turning C1E and EIST removes the problem..
-
sorry for the double post..
but I read that in the corsair fourm they list that disabling C1E removes noise if experienced...
so a state like that tells me that this issue is common and not related to PSUs...
am I right?
-
There are many issues with noise at the moment and most of them are "cured" by disabling the power saving options in hte BIOS. Obviously these are really only a temporary workaround but do stop the noise. There have been some breakthroughs recently especially on the UD3 boards where Gigabyte are doing a hardware fix on the motherboard itself. As far as I am aware this only applies to the UD3. This seems to be caused by a incompatibility between the motherboard and the PSU and has nothing to do with the quality of either component. At the moment it is a case of stopping the noise for now whilst waiting for a fix to be found.
-
Like I said I'm just asking you to Contact Thermaltake and see if they think its the PSU.
Just an idea try running the PSU off your UPS without your UPS plugged in the mains.
-
I tried operating it without the UPS, and the noise still exists ...
tried isolating the GPU by replacing the graphics card, and the noise still exists...
-
What response did you get from Thermaltake?
-
I've sent an email, didn't reply yet..
I will post as soon as they will..
side question..
shouldn't the PWR_FAN header drive case fans to full speed?
because I've noticed while monitoring the rpms of the fans connected to mobo headers, that they are all running @1300rpm, while the fan connected to PWR_FAN header running @1120rpm..
-
Are they all the same fans anyway? Different fans will run at different speeds.
-
I tried operating it without the UPS, and the noise still exists ...
No..no with the UPS so that you unplug it and it powers the PSU.
-
What Peter is saying is leave the computer plugged into the UPS but unplug the UPS from the mains supply. That way you will be using as DC inverted to AC power supply that is very smooth.
-
the fans are all the same...
about the UPS..
no, my UPS on battery makes very bad noise through the PSU... its something related to the sine wave output I've read on the web...
very bad noise, loud and scary :), even if the PC is shut down.
-
Slightly off topic but what make/model of UPS are you using? It should be silent.
-
its a crappy PSU too, not a fancy brand...
btw, its not the UPS that makes the noise,..
the UPS on battery causes my PSU to make horrible noise..
another thing, whats the cause of this random internal speaker beep, that occasionally happens during using windows ?
is the c-states causing this?
-
No, I did realise the noise was coming from the PSU not the UPS but I was just interested in why the even "crappy PSU" would make such a noise. It should be silent almost. If it is being fed an almost perfect sine wave input I would have expected it to be quite happy. :-\
While I was just re-reading your thread it occurred to me that you could always use another PSU in tandem as a slave PSU and that way increase the output for trial purposes.
-

Yes its a feature by Intel that random beep I had gigabyte support look it up about year a go but you should only get it if C-State and CPU Warning Temperature is set.
...and your Thermaltake toughpower PSU is by no means crappy its high end.
-
...and your Thermaltake toughpower PSU is by no means crappy its high end.
My thoughts exactly.
-
...and your Thermaltake toughpower PSU is by no means crappy its high end.
and yet this is my reward :/
-
I had the same sort of problem when I built this latest system and bought a Zalman Heatpipe 750W PSU that was supposed to be the mutt's nuts but it wouldn't work with my setup. I then bought a Corsair HX850 and it worked fine. ;)
-
so... to be able to sleep well..
is a replacement is a must.
or I should not be concerned by this issue at all? is if its not there?
-
I am afraid that must be YOUR choice. ;)
-
so its not clear if this issue would cause future probelsm...
-
ok,
after talking the psu tech support, they told me that the psu should not make any noise, and assume that it may be faulty and I should RMA it...
but from a week ago, I noticed that the mobo as well started making clicking/tapping noises around the CPU area when PC is doing stuff !!
so now I am confused... is the psu did something to the mobo?
or its the mobo that its faulty?
or is it both of them?
-
I would think that it is more likely a combination of the both of them. You would probably find seperately they would both work fine but they just don't like each other. It may well be the best cousrse of action though to RMA your PSU if they have OKed it as a different one might be fine with this motherboard.
-

I see...
but there is a point that I don't understand...
if the motherboard is defective, could it cause the PSU to make screeching noise?
also, if the PSU is defective, could it cause the motherboard to make this clicking noise?
I wanna know, which of the two to rma, cause now I am confused and don't want to send something for RMA and turns out to be fine.
thanks
-
As I have tried to explain it is not necessarily a case of either of them being defective just that when a product is made it is allowed to be within certain tolerances and these can either add up or cancel each other out. So in some cases you will end up with a problem in others not.

yeah I get that..
I am just asking this, because I tried as hard as I can to remember if the previous unit before RMA did the same thing or not...
you know as I said before, I had 2 exact PSU like this one before and got replaced...
the first one, if I remember correctly, It didn't make this noise...
and the second one, lasted about 10 min after first boot and BAM! stopped working...
so I am afraid that this second one did something to the motherboard which maybe causing this issue with the third PSU unit..
so thats why I asked those previous question in case hypothetically there is a defective unit of the two..
so what do you think?
-
I don't think that the previous PSU "popping it's cloggs" has anything to do with the noises that you are now experiencing. I think it is highly likely that if you were to change either components the noise would abate.
If the noise is the same as has plagued the UD3Rs it has something to do with feedback and Gigabyte now has a hardware fix for it. So I am sure that if the same they will expand this fix to cover the other platforms also.

I don't know if the problem is similar to the UD3Rs
because from what I've read, they experience whining noise or squieling around the CPU area..
but the sound I am getting is different, Its more like tapping noises or clicking, like when HDDs click...
-
Maybe it is different then but there have been a lot of different noises from the UD3R boards. It sounds more like a relay not latching properly or something like that then. I would get the PSU replaced again.
