Need help: Rig artifacts when OC'd.

[OmegaSupreme]

As the title says, when I OC my rig it gets artifacts in game (FC2) and when I run 3dmark 06 it sort of "skips" once every second in 3 of the 4 GPU tests (the only one it doesn't do it in is firefly forest).

So here's how I have it setup

HTT(FSB): 225
CPU:3600MHz
NB:2700Mhz
MEM: DDR3 1500 @ 7-7-7-20-27-1T
GPU(s): At stock clocks
All of the above setting have been tested for stability using Memtest, Prime and S&M V1.9.1 and have passed w/o issue.

However, when I run it at this speed I get the erky jerky video during 3dm06 and when trying to play farcry 2 I get some rather large artifacts on the right side of the screen. The artifacts show up in the same place. It's not random as with a bad GPU overclock. And like I said it's rather large. On my 22" screen it's a black bar that's 3" wide by 8" tall. It only flashes every few seconds.

Any idea's as to what might be causing this?

Also, I noticed this when I got my results from the FC2 benchmark.

Initial run (@ stock) looked like this

My overclocked run looked like this

Any idea's what would cause it to have the saw tooth pattern?

So the system is stable when not OC'd, right?

So, what happens when you run FurMark?

Try relaxing the timings on your RAM and make sure the PCI-E bus isn't OC'd.

As far as I can tell yeah its stable. Although now I get the saw tooth pattern at stock speeds too.

So, what happens when you run FurMark?

Try relaxing the timings on your RAM and make sure the PCI-E bus isn't OC'd.

I dropped the ram down to 1333 with 6-5-5-15-20-1T timings. It made 19 passes through memtest with no errors.I'll try relaxing them to 8-8-8-24 to see if it makes a difference.

Haven't run furmark but I'll give it a go.
As far as I can tell the PCIe bus is locked.

Turns out that the game file became corrupted, re-installed and everything's ok.

so 3dMark is running fine now without stuttering?

Haven't re-installed 3dm06 yet. But far cry seems to be ok. I'll post an update as soon as I re-install.
