GA-X58A-UD3R electrical noises [solved]

[Dark Mantis]

Hi Peter
There must be many UD3 boards that are working perfectly, it's just that with the quantity that are causing the noise problem it's a case of trying to find certain similarities. It has been suggested that the PSU/motherboard mix is one that could be the cause.

Does the Asus board have features like C1E, C3/C6/C7 state, and EIST etc?

Yes, Yes (but not on by default, I did enable it), no idea.

Thanks. Do you mind to share the type of graphical card installed in your system?

I've been watching this thread for a while now and thought I would post my experience.

I built a Core i7 930 system a couple of months back using a GA-X58A-UD3R rev 1 board and 6GB of Corsair DDR3-1600 ram (XMP profile 1 enabled in bios). The system build went ok but I immediately noticed the high pitched noise described in this thread, it was coming from the CPU area and not the Seasonic X-750 power supply. The noise was very much reduced with C1E disabled.

I was willing to live with the quiet high pitched noise but I began to suffer from random crashing, particularly in games such as COD4. No blue screen of death, just instant reboot. A full hardware and software rebuild later and the same issue occurs, I eventually isolate the power supply as the most likely cause.

To cut a long story short, I bought a Corsair TX 650w power supply to prove my theory (rather than return all the bits to Scan) and I now have perfect stability with only slight coil whine when C1E is enabled (perfectly silent when disabled). I may have had a faulty Seasonic X-750 (now refunded) but this particular PSU has come up a couple of times in this thread, either way I'm much happier now.

Thanks for that information burgerking,The more we can assimilate the more chance of getting to the bottom of this fiasco

I recieved my X58A-UD9 Friday and it has 0 whine issues so I dont understand why Gigabyte has not fixed the UD3R issue yet. I will keep you updated. Awesome board so far.

To my way of thinking the main difference between the two boards apart from the obvious, size, slots, etc is the the UD7/9 has 24 power phases and the UD3 only has 8 on the rev1 board and 12 on the rev2. So presumably Gigabyte are thinking along the same lines.

Hopefully Gigabyte will allow us to exchange for UD9... Ha Ha... I'm dreaming...

Can I join in the dream? UD9s all round!

Hi Guys,

Is there any update on this? I don't have the problem with C1 and C3-4-5 set on disabled but i don't know if i'm doing something wrong for my cpu lifetime...

Someone can confirm that i can have these 2 options disabled?

Which bios do you suggest me to use to fix the issue? The last beta bios on the site can help?

Thanks

In theory it will shorten the lifespan of your chip but in reality you will probably discard the chip and upgrade it before it burns out. It is only the fact that it allows the CPU to throttle back when not being used. Because of this you will use slightly more energy too.

So as i understood there is no solution at all for this problem....

[Dark Mantis]

Not so far Gigabyte has been working on different BIOS updates but whether that will fix the problem reamains debateable.

I double checked the voltage value of the cpu without C1 and C4-5-6 and finally i saw that the difference in idle its not so much. I have the cpu voltage set up in Idle and the voltage change in lower and higer "normally". For sure with the C1 and C4\5\6 options its a bit lower in idle and uses also different small values BUT the difference its not so much.
So i think that its not a big problem to leave these options disables.

At least till Gigabyte will not fix definitely the issue with a Bios update.

Last question:

I wanted to use the Dynamic Energy Saver2 utility to save power in windows 7 but the application doesn't work for me. It stucks whenever i try to enable it. Is there a working application for I7\Win7 64bit that is working fine to save energy\power?

Thank you

[Dark Mantis]

I don't use the power saving modes C1 etc either becuase I watercool everything and so it would be counter productive. The bundled software is usually rubbish in my opinion and I would suggest not using it. Normally only causes problems. As I say I am the wrong person to answer your question about power saving programs, but I am sure there are others who will be happy to.
