Changed GPU settings, now sudden flashes of black on display

I went into CCC earlier and put all of my GPU settings to their max quality, and now my whole display will go black and suddenly return. It only happens for a millisecond, and at random times as well, mainly when scrolling a page. I turned it back to defaults and the issue stopped. Is there a way I can keep my GPU overclocked without the black flashes?

You are describing two entirely different things between those statements.

If it's flashing when overclocked then clearly it's unstable at those clocks.

Lol I'm dumb... I used CCC to put it at max quality settings (like I adjusted the color and 3D acceleration) and that's when I got the black flashes. I reset the quality to medium balanced and the issue stopped.

Sapphire TriXX is what I use and imo it's better for Radeon cards..

I installed TriXX and overclocked my 6950. I overclocked it too high the first time and crashed the system, but I found a decent overclock that seems to be working well.
I took the GPU clock from 800MHz to 930MHz, and I took the memory clock from 1249MHz up to 1302MHz. Any higher and I crash the system, but with how high I got it to go, I am satisfied.

Just make sure you enable custom fan profiles in the MSI Afterburner to ensure you don't cook it. ;) Well done. Tell us the what you achieved % wise in FPS, I bet its like less than 5%.

I have my fan set at 50% fixed and it seems to be working fine. After I saved my settings, I tried to load TF2 but it locked up at 5FPS and crashed :( I reset my GPU clocks to stock and TF2 played fine...

Now, do you think it was more likely the GPU clock or the memory clock that caused the issue?

Either one can cause it, which is why you should increase both separately. For instance I overlocked my 980 Ti until I started getting crashes in 3DMark, so I lowered the core speed and continued to raise the memory speed.

Which one, GPU or memory, will make the biggest FPS difference?
 
Memory is the one that always causes issues. Again, I ask, you what benefit do you think you'll gain. I given up on overclocking GPUs.

Well when you have overclocked dual 980 Ti's there's not much point... To those of us without a computer worth that of a used car, overclocking is still valuable.
