Ok, so i couldn't take it and not upgrade to a pci-express video card any longer. So i got a A8N32-SLi for the socket 939 platform, with an 8800 gts. Here is my current system components:
A8N32 Sli Deluxe
AMD 4000+ San Diego
EVGA 8800 GTS 320 Superclocked
Scythe Ninja Ultra revision 2 Heatpipe tower
2x512 Kingmax DDR500
HIPER Type R 580W PSU
2x80gig WD raid 0 SATA
So i get the system put together and up and running. Run some stress tests with like oblivion, prime95 etc and things look cool. Temps are good on the cpu, system temps were hot but i found that when i put the fan on the mobo heatpipe that they came down. So i decided to try my hand at oc this bad boy. I was able to get this same cpu to 2.8 on an MSI K8N Neo 2 so i figured that would be my goal here as well. I kinda followed the Anandtech forums quick and dirty isolate/combine process for overclocking and found that my cpu would run prime 95 without errors to 2820 mhz. The mobo would take it's FSB over 330 with the cpu multiplier down to 7, and the memory tested good with memtest to 255.
However, when i went to put a combo of fsb 250 x 11 for a 2750 speed 3dmark 2006 would bomb out on the first test with graphical errors. The computer itself wouldn't crash though. I could escape out of 3dmark and it would just tell me the test was aborted. I tried firing up oblivion, and the same thing happened, tons of grapical errors but not system crashing and returned to desktop ok. Prime 95 ran without errors as well. I kept trying to play with slightly lower values and found that the only speed i could run was 11x235 for a 185 mhz overclock =/
If prime95 doesn't run into any errors, but 3dmark and oblivion crash out what could it be? I was thinking i could try to slow down the memory in case that was the problem, but I don't see how that could be if i could run ok at 10x250 without a problem. I'm certainly dissapointed that i can't get more out of this overclock at the moment to not bottlneck my video card so much. Any ideas or suggestions would be appreciated.
*NB HTT ratio is 4x
*SB HTT ratio is locked at 5x by 200 frequency
i've also tried increasing cpu voltage, but it makes no difference.
thanks for the help.
