I7 build issues, strange noise

modo77 · 8 Apr 2010 at 16:19

Hi folks,

Just setup my new system, and having a slightly annoying issue. The pc is making some strange noises. This happens randomly, but certain things make it far worse. i.e. transferring files over the onboard Ethernet.

The noise itself would be best described as the old style MODEM noises

The cpu,mb and ram are new:

Intel Core i7 930 2.80GHz
Gigabyte GA-X58A-UD3R Intel X58
Patriot Viper 6GB PC3-12800C8 (1600MHz)
ATI 5850

Any ideas?

Edit: Should just point out that apart from the noise it seems to be running perfectly, its a little odd

Do you have speedstep enabled?

Just had a look in the bios and can't see an option for it anywhere. Everything is pretty much on default at the moment

Check for C1E & EIST.

Mobo capacitor whine possibly? I know from personal experience the 680i's suffered from it badly?

Is the noise coming from your on-board sound or through the speakers etc? It could be a soundcard problem?

Yeah both of those where enabled, disabled them now and it seems to have stopped. just going to grab my laptop and copy something over

Any downside to disabling those?

Nah its not from the soundcard. its off the mb.

Yup its deffinatly stopped with C1E and EIST disabled, cheers

Any idea why they cause the noise? do i need to return the mb if its a fault?

Mine does the same, I have the older std UD5, I think it's the MOSFETS - or what ever they are called around the cpu which make the noise.

sorry if its a bit of n00b question but whats C1E and EIST?

I was thinking of getting the same mobo/CPU combination!
