I have overclocked for many years and I read all the great things about the Q6600 G0, my temps are great and everything is fine. Well I finally decided I need to overclock for some better framerates and I am having the worst luck ever.
Asus P5B
Intel Q6600 G0 w/ Arctic Cooling Freezer 7 Pro
4x1GB Corsair 6400 (800Mhz)
XFX 8800GTX
2 HDs - WD 250 and 160 SATA drives
1 DVD/CD combo burner drive
PSU CORSAIR 620HX 620W
I just set the FSB to a mere 320mhz (~2880mhz for CPU) so as to allow my RAM to stay at 800mhz (4:5 ratio) and RAM is already at 5-5-5-15. CoreV set to 1.4625v and I get apps crashing every 5 min and prime95 errors within 1-2 minutes. I have no idea what to do because it fails so quickly. Mobo BIOS is newest, ver. 2001. The temps stay below 60C easy underload (at least as long as the stress test lasts), all cores idle around 37-40C in a 23C room. Ran Memtest86, 0 errors so RAM modules aren't faulty. When running stock settings I, of course, have no crashing of apps and prime95 ran for the 2 hours I let it go for.
I always thought an increase in core voltage is the way to solve instability but I hear people running this CPU at 3.2 at around 1.4 volts. I can't even get 2.9 stable at 1.465 volts????
If there is something I am forgetting please someone snap me into reality. Is my PSU not enough? it has 3 12V rails...
I am currently CLUELESS and need any suggestions, thanks.
Edit - I just tried setting core voltage to auto since many have gotten to 3.0-3.2ghz with Auto and Prime95 has 2 cores error within a minute. I think I got the worst Q6600 to roll of the line...
Edit 2 - Ok, looks like I may have found the issue, sort of. I am still set to Auto for the core voltage and for the hell of it changed the RAM divider to 1:1 causing the RAM to run at 640mhz instead of 800mhz. As I am writing this Prime95 is still going error FREE, 55-57C, for 30min, much better than the 20 SECONDS it took to error 2 cores. So my only guess is some of my RAM can't handle the increased FSB even when the divider causes them to keep running at their designed speed of 800mhz. I could always go buy another 4GB and goto 1066mhz RAM

52 bucks plus tax, not a bad deal. If anyone thinks getting new RAM such as this is the likely solution (or if you DON'T think so as well) let me know.
