for those of you who are OCing using a DS3 motherboard, with your givin OC what are you using for MCH and FSB overvoltage? Im currently using MCH = +2 and FSB = +2. My OC is now @ 460*7. I had these settings left at stock until I go over 455FSB I start getting stability issues. I've run SP2004 for hours with no issues, i've 32mb PI'ed and no issues there either. But sometimes while playing fear my sound locks up, and the game freezes, **OR** as soon as I exit the game and im back at the desktop, if I move the mouse the same thing happens. Some hissing sound comes from the speakers and the PC locks up. I cant understand this :mad: I can PRIME for hours, and pass all these stability test (memtest also) but my PC locks up SOMETIMES!!! So as I said in the first part of this post, I upped the MCH and FSB voltage settings, and I'll see how it goes......
 
how many hours of prime stress?

one assumption might be your CPU temp was too hot?
 
a little over 4 hours, and my temps arent an issue. While using sp2004 both cores never went over 53c......... I logged it using core temp ;) Seems weird though, doesnt it? Im wondering if my XF-i drivers are causing this? If or when this happens again, i'll uninstall the XF-I drivers, and the card itself, and try the built in sound on the motherboard and see if it happens again......
 
Everything I recall seeing seem to indicate overvolting the mch and fsb actually can have a negative effect on overclocking if above the first additioanl voltage setting. I give mine +.05V and have tried higher with no effect on my max overclock. Of course every board is different.

ditto on Orthos

G.Skill DDR2 800 PC6400 2x1GB @ 900Mhz 4/4/4/12 (HZ)

loosen ram to 5 5 5 12 and I bet the lockups go away. You wont even notice any performace difference.
 
You do not need to loosen the timming of the memory, because this dual kit is fully capable of doing it at 4-4-4-12.

Look at mine :) - same ram

Ya, this ram is really good, if I get no errors in memtest, then I see no need to change the timings.
 
What kind of cooling do you have on the NB? Just curious.

And what version of the XFi drivers are you using?

Im using the newest XF-I driver from creatives site, and I have a 40mm fan on the northbridge.
