p55a-ud6 making PSU make screeching noise when C1e/EIST on

[pink_waters]

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.

[pink_waters]

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...

[Dark Mantis]

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.

[pink_waters]

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

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.
