Artifacting When Overclocked

post #1 of 7
Thread Starter 
Hello, I am currently trying to push my rig again and see if I can get any more out of it. When ever I get >3.8. I get artifacts on my screen, and I know it wont be stable. Is there a particular cause to this? or is it just basic instability?

If you're artifacting in windows on a cpu overclock it's probably because you're pushing your ram too far, lower the multiplier on the ram and test again.

No matter what my Ram is set to it seems to happen whenever I start windows. There is a flash of blue and red stripes and then it goes away...

Currently I have my Ram set at 6.66 x 206 (1372Mhz) with a voltage of 1.65..

Thought it might be CCC but so I rolled back my drivers on my card, and still no luck...

You could stress your gpu just to rule it out.

What are your ram timings? You are currently overclocking them afaik.


You should probably drop your ram voltage though, 1.65 for almost no overclock over factory on ram that is 1.5v for 1333.

My ram timings are 9-9-9-24, I had my ram voltage set at 1.65 because I read that is what the 'recommended' voltage is for the RAM, also to stabilize my CPU OC, I can lower it down to 1.5 and see how it goes.

Also I am currently playing around with 3dmark11 and Ill do some furmark runs to rule out the GPU

Don't lower your Ram voltage! I have the Corsair Dominators which are similar and these cause all kinds of problems when the voltage is below 1.65. I have moved them up to 1.67 and it helped out a little more.

You can lower the voltages if you want, Im not trying to be bossy. I have just had a bad experience with my ram voltages being too low.

I think the culprit might have been the NB freq actually... Was running at 208x12, lowered it down to 11x and it seems a little better, no noticeable colors, there is still a slight desktop shift for a split second when I first boot...
