8rda+ sound problems when running high fsb hi guys, some days ago, i did the vdd mod - now i can go up to fsb210, but after some stress for the cpu, my sound won't work anymore! eg when i run prime torture test for a about 20min and then start winamp, it will cut off and take about 70% of the cpu time?? i have a zalman on both the northbridge and the southbridge and my vdd currently is @ 1.75v. can anybody help??

APIC won't cause the problem he's having with onboard sound. If you clock down the fsb and the prob goes away (as I assume it does based off of your description) then you just have the fsb too high. Back off a bit.

Re: 8rda+ sound problems when running high fsb Quote:
I got the same prob - High FSB = sound disables. To fix this, you have to apply more voltage to the NB to stabalize it. A good way to make sure your NB has enuff voltage is to run 3dmark or Q3 and look closely for graphic artifacts/glitches. If you get artifacts, apply more vdd voltage until they go away. And keep that NB cool. I had a 60mm Al cpu heatsink and 60mm fan on my NB with lapping and AS Epoxy. It ran 232FSB @ 2.2v pretty cool @ 32C idle, but not stable (think my PSU is the problem) Damnit, you can apply up to 2.3v max on the A3 chipset, but make sure you have a quality PSU with 400w+! Running my NB @ 2.2v for days 24/7 didnt damage it, but using a 250w cheap PSU on my mobo for "testing" fried a little chip on my mobo.
