• Strange desktop glitches when overclocking

Specs: 3GHz AMD Athlon II x4 640 8GB Kingston HyperX Ram 2TB Samsung SD103SJ 1GB Radeon HD 5750 Vapor-x Basically I can overclock the card really well due to the vapor-x cooler. I've overclocked it (from 710MHz/1160MHz) to 850MHz/1300MHz and ran it under furmark for 3 hours without so much as a glitch. The temps have been steady ranging from 40c idle, up to about 70c (though using furmarks xtreme burn in test it has hit up to 76c). Basically everything runs fine but if I drag a window (such a browser, or explorer) one of my 2 monitors will do a weird artifact. It happens regardless of how much I overclock or whether I overclock the core or memory. Even just a 5mhz overclock on either will cause the issue to start. It also seems to happen on any screen, Here's a video of the issue with me dragging a window between my screens.

Also the glitch doesn't happen when I'm using only 1 of my monitors.
I've had something like this happen due to buggy drivers on an old laptop (ATi M1 era). Basically, running certain types of applications or moving Windows around would cause the right side of the screen to display artifacts. That was fixed by updating drivers. I suspect in this case you may want to try downgrading your drivers to Catalyst 12 if you're on 13.1. If not, try the Beta drivers.
This looks like a simple processing error (the graphics getting ahead of the CPU). As the user said above downgrading the driver and if that fails try lower refresh rate On a side note bring the power down high overclocking does nothing but damage to your system, even tho you are keeping temperature down you are doing outputs the card was never made to do.

Heck it's running a vapor-x cooler which is basically an overclocking cooler. Everything is stable aside from the desktop glitches, which as said in my first post don't appear if I disable one of my 2 monitors. I have yet to try an older driver version, but I shall try that very soon.
