So, I got a HD 5570 (stock - 650|800)and decided to overclock it a bit. I bumped up the core and memory 50MHz, ran ATITool for 30 minutes and played GTA 4 for a little while to check stability. It was all fine, so i bumped it up another 50MHz (750|900) I did the same tests as before and it was fine. I then put up the memory to 930MHz and everything was good. By now, at full load my temps were reaching only 50C max. So i load up GTA 4 and run the benchmark tool, but while it's loading i get a BSOD.
So i turn my pc back on and immediately use ATITool. And i got HEAPS of artifacts. It didn't say there were any errors, just delta things and there was heaps of yellow lines everywhere. So i downclock my video card 20MHz at a time to see if it becomes stable. I get back down to stock speeds and it's still showing artifacts So, i take my new video card out and reboot. I enter the BIOS and put my onboard HD 4200 core back to 500MHz and save. I go back to windows and run ATiTool, and sure enough i still had artifacts. So i test different resolutions and it turns out the artifacts only appear at the resolution 1152x648 and above. So i run ATITool once again, and it still has artifacts, then i click the close 3D window button, then i click scan for artifacts agin and no artifacts show up... I am really confused as to what is causing the artifacts and any help would be much appreciated Could it be because of corrupted software such as drivers? Thanks.
Extra details: im using windows 7 ultimate 64bit
i have a gigabyte hd 5570 DDR3 model
my mobo is a asus m4a785td-m evo
i have a phenom 550 3.1GHz cpu
Some photos: (cause screenshots don't seem to capture the artifacts...)
