Forum Overclocking : Graphics Cards Gpu Overclocking Glitch Issues

Hello guys, glad to be back gaining knowledge from the pros Anyways I have an xfx 6850 and have been using the latest drivers, yet whenever I try overclocking it(With Msi afterburner) I seem to always experience glitches such as freezing, a certain portion of the right of my screen showing on the left (I don't know what people call it), etc. Can anyone help me solve this issue, because this is causing me not to be able to oc

I am oc the stock core clock from 800 to 875 and the memory clock from 1050 to 1250. It is staying at about 50C or less, and the heat doesn't seem to be the issue.

Those temps seems to be too low to me. That oc is pretty high though. Try increasing voltage. Smallest possible.

Well those temps are rather estimates as I haven't yet monitored them while play my graphics heavy games (BF3), and I don't enjoy having to restart my computer after the screen glitches out, but I'll be sure to come back to you with more accurate temps later on.

Alright just got done testing my temps and it seems to maxing out at 75C (sorry for my other calculation being totally random and not even close). I also was speaking to a friend about this and he also recommended volage oc. All I need to do now is finding out how to unlock the oc voltage on afterburner because it won't unlock in the options menu
