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

[Peteruk]

another thing, whats the cause of this random internal speaker beep, that occasionally happens during using windows ?
is the c-states causing this?

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.

My thoughts exactly.

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?

[Dark Mantis]

I am afraid that must be YOUR choice.

[pink_waters]

so its not clear if this issue would cause future probelsm...

[pink_waters]

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?

[Dark Mantis]

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...

[Dark Mantis]

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.
