Bought a 7970 - seeing "artifacts" in non-load

post #1 of 5
Thread Starter 
So, since I bought my Sapphire HD 7970 I've noticed that there are artifacts (basically a lot of miscoloured lines) showing up on my screen while I'm not playing, for less than 0.5 seconds each. Sometimes they appear in shorter intervals and sometimes they apper in longer intervals. I have overclocked, but I don't think that matters since I saw them before I changed the clock speeds, and since I don't see them when the GPU is in heavy load (Heavens Benchmark).

I did some research and I saw that a driver issue could cause this. I had an AMD card earlier (5850), but I didn't format my computer, I just uninstalled the previous drivers and installed new fresh ones. I also read that the card could be defect, but if it would, wouldn't I get these issues while playing as well?

Could there be something else that causes this?

If you're using MSI Afterburner, or any other program that uses anything like "Unofficial Overclocking Method", that would explain the artifacting. If you're bypassing CCC's OverDrive clock limits, you're likely using an unofficial method.

The artifacting occurs when the core clock speed changes; could be pretty common on the desktop, but games tend to keep clocks at the highest.

Yes, I am using MSI Afterburner. So what's the solution to this? Completely reset the clocks to stock speeds, uninstall MSI Afterburner and re-overclock via CCC?

Is it a small box with checkerboard pattern that randomly appears? For me i noticed i had to lower memory speed when that happens.

Under settings on the very first tab towards the bottom, there should be something to modify whether or not to use Unofficial overclocking methods. I can't recall if it's a checkbox or what though, but if it's on at all, regardless of if you OC or not, the artifacting will occur.

I believe there's something towards the bottom of the first settings tab to extend the clocks past CCC's limit that's separate from the unofficial overclock method. If you need extended clocks, try that setting out instead and reboot.
