Simple problem, hopefully simple answer, but I simply CANNOT find it.
When running CoD2 and 3DMark05/06, my video display "stutters". I DON'T MEAN LAG. I mean "stutter". It runs smoother, then stutters REGULARLY approximately every 5 seconds for 1.5 seconds, then continues, then stutters. It keeps going like this without end. This doesn't seem to affect my benchmark scores though, which is weird.
System specs:
-6300 OC'd to 3.0 (but I tried stock speeds)
-Zalman 9500
-2x1024 OCZ Platinum @ 4-5-4-15
-Gigabyte 965P-DS3
-EVGA 8800GTS
-Seasonic Energy Plus 650w
-3 Seagate/WD hard drives
Info on what I've tried:
-temps on CPU are good
-temps on 8800GTS top out in the low 70's celcius
-My OC is STABLE, dual Prime 95's for 24 hours no errors
-drivers are current
-BIOS is current
-DX9 updated
-game updated
-no RAID
-tried 4 different NVIDIA cards (7600GT, another 7600GT, 7900GTX, 8800GTS), still stutters on ALL of them
-tried a new mobo, still stutters
-tried 2 other PSUs, still stutters
-tried 2 different hard drives, still stutters
-tried one RAM stick, then tried the other, each in separate DIMM slots, 1 at a time.
-ran memtest, no errors (but how LONG/passes should I let it run???)
-checked virtual memory settings, seem fine
-tried running CoD2 on Affinity set just to CPU0, then just CPU 1, then both
-write combining on and off (I'm positive I did this and no fix)
So I've proven it's not the game. It's not the mobo, PSU, vid card, CPU temp, hard drive, OC, BIOS.
So either:
-CPU is problematic (doubt it, no issues with all benchies/stress tests I can find)
-RAM is problematic (and haven't let Memtest run long enough to find possible errors)
-system setup is problematic......no idea where though
-driver issue (but I've tried 4 diff vid cards, so it would be a setup thing I would hypothesize)
-all the cards or CPU/system is throttling, but I can't tell if it is, or what would be causing it. Or how to fix it.
I think I've covered all my bases. Weak points (RAM, setting, etc) noted above.
Has ANYONE got any ideas? Serious replies only, this is very frustrating and I've gone through the gamut of things and done lots of reading and research to try to nail this problem down.
Cookie and bragging rights to the person who can figure this out LOL.
Thanks.
