Title: ph67-ud-b3 terrible whine when c3/c6 enabled
Post by: sezec on March 09, 2011, 01:39:49 am
I waited for a long time for the b3 motherboard to avoid any hassle with returns then the gigabyte ph67-ud-b3 today it came. ironically....
I boot up for first time and soon as it gets to windows loading I hear a really bad whine, I took out any fans and located it to either the CPU plate or coils around that area.

Further testing I found it doesn't do it under windows xp, it does do it on windows boot dvd/recovery and no hardware or PSU changes it. It changes depending on CPU load (worst when idle) and it does it no matter what power options I use in windows 7.
The only thing I've found that fixed the noise was 'c3/c6 state support' in BIOS which was advised in alot of other threads with similar problems. This however comes at unacceptable draw backs of increased power usage and no TurboBoost on my i5-2500k!

I found a post here: http://forum.giga-byte.co.uk/index.php?topic=3877.0 where a BIOS update corrected it. However there seems to be no BIOS updates for mine.
Do you have any suggestions or info before I have to RMA?

Hi and welcome to the Gigabyte Forum.

Of course these boards are very new to the marketplace and so not many instances of them exist as yet. Even so I have not heard of any other motherboards in this range that have this fault.

Does it still make the noise if EIST is disabled ?

I would PM runn3R our Gigabyte Forum Administrator as I am sure he would be interested in this board and can tell you the best way to continue.

Hi, thanks for the reply. I tried disabling EIST, and EIST + c1e but it made no difference while c3/c6 was enabled.
I did however notice the noise reduced when I unplugged USB devices. But still audible.

I have the exact same problem with my P67A-UD5 w/2600k. Running with Turbo Boost off because of it.   :(

I would advise you to do the same then paincakes. It also wouldn't hurt to contact GGTS so they know of the problem.

Just enter your email address and click on the language of choice.

Any ideas why the noise would dim when I unplug all the USB and PS/2 ?

The only reason I can think of would be crosstalk. Were the USB devices connected to the rear motherboard connectors or the front of the machine or even via a hub?

Don't know if this helps, but my UD5-B3 does't whin at all.

If you guys would like to post you bios setting when yours whin, I'll try and replicate for you.

As far as I understand it they have the problem all the time when C3,C6 is enabled. I take it the rest of the BIOS settings are set to Optimal.

I have the original board and I can't make any noises come out of it by adjusting the BIOS power saver settings.

using mine with C3/C6 enabled, no whine at all. Sorry boy's - mine is a B3 revision.

That surprises me, your sure you're not tone deaf, working for Gigabyte, got some loud fan migrating the noise or not using windows 7. I would bet money on it as I'm sure they all do it.

Are you trying to say all UD5s make that noise because if so you are dreadfully mistaken. My UD5 (original board) is quiet as a mouse that has had a laryngectomy!

I'll be installing my replacement P67A-UD5-B3 next week, will report back I know this noise well...

Many times this is actually caused by various power supplies. 

I do know what the noise sounds like, and have heard it on a GIGABYTE board at a friends, but have never heard it on any of my multiple handfuls of boards all using only 1-3 different power supplies.   I did test my friends PSU on two of my boards, and then the noise could be heard, so more often than anyone wants to hear, the PSU is the main cause of this issue.

Yes I agree as with the older X58A-UD3 boards it was down to a combination of board and power supply but most motherboard/PSU combinations were perfectly silent.

I can confirm, no noise from my board.

No, most boards work perfectly. It seems that there is a small percentage that have a problem when married up to certain power supplies.

Hey. I RMA my Gigabyte, got a Asus P8H67-M LX which was about half as loud then finnaly bought a expensive MSI P67A-C65 with the advert of "whistle free", well guess what, this one does it too. Disabling C state only way to fix. Tested all with 3 differant PSU and power sockets as well as fanless cpu/gpu and PSU wired to another room.
However Gigabyte board was by far the worst in loudness, Asus was bad enough to hear and MSI with all my fans on with case closed under my desk I can just about make it out(I think, hard to determin source).

I bought a USB PCI controller when I found unplugging all USB seemed to dim it, but it doesn't seem to on MSI board, I'm going to have to put up with it and bin it when a new model comes out.

Good luck with your replacement, i'm pretty conviced all 1155 boards do though and no one accually sits them on a test bed, they just stick them in their case and end up thinking the noise is from their PSU etc.

Hi I can assure you that you are wrong there in your assumption as I have one running here right next to me on a testbench that is perfectly quiet. See the thread here :   http://forum.giga-byte.co.uk/index.php/topic,4776.0.html

Agree with DM - no problems for me.

Thanks for info, think I'll buy another PSU to test. Ps. have you tested under windows 7? It doesn't do it under XP.

Post by: Dark Mantis on March 17, 2011, 09:58:29 pm
Yes I am testing under Win7 64 bit.

I've tried Casecom 500w, ozc gamextream 700w, antec true power 650w and coolermaster pro m 600w, most of them on 3 differant 1155 boards and all make no differance. Seems like it has to be the boards, must be a high number of them if 3/3 did it. :S

I am using a Gigabyte ODIN Pro 1200W PSU but I will swap it out for a Zalman Heatpipe 750W PSU shortly just to see if it makes any difference.
Title: Re: ph67-ud-b3 terrible whine when c3/c6 enabled
Post by: Dark Mantis on March 21, 2011, 01:53:18 pm
Well I can report that there is still no undue noises coming from either the PSU or the motherboard with the Zalman Heatpipe 750W PSU powering the system either. Apart from the whisper of the fans it is absolutely silent! 8)

Just installed the P67A-UD5-B3 I got for replacement due to Intel recall and the whine is back under the same conditions. I have C3/C6 disabled again to stop it. Next step is to try another power supply I guess, using Antec Neo Power 650 right now. People without the whine make sure your bios has the C3/C6 state set to "Enabled" as opposed to "Auto". For some reason if you run XMP memory profile "Auto" actually disables C3/C6.

EDIT: you can grab the Intel Turbo Boost Technology Monitor for Windows 7. This app will let you know if C3/C6 is properly enabled as you can watch your Turbo Boost function with this monitor.

I can confirm now that even with C3/C6 enabled and TurboBoost functioning there are no extraneous noises coming from my system. Totally silent. 8)
