Screen flickers after overclocking.

post #1 of 7
Thread Starter 
Hi all,

I have an overclocking problem, whenever I overclock my Sapphire Radeon HD 6770 1gb with MSI Afterburner my screen starts to flicker. (Also have the same problem with Sapphire Trixx)
It is stable if I use AMD Overdrive with Core: 800 MHz and Memory: 1250 MHz.
Here is my current OC, if it helps anything.

If it starts to flicker or produces artifacts, then it's not stable and producing visual errors. Wind down the clocks to the last stable setting or more voltage is going to be required.

Ok, and how to I accomplish more voltage, because in msi afterburner it doesn't show even if I enable it in the settings.

EDIT: It only does it in browser and desktop NOT in games..

I had this problem too on my card, most likely its your AMD Catalyst overclock profiles competing with Trixx and MSI Afterburner. Try opening CCC and changing your resolution back and forth after overclocking, should fix the problem.

If this isn't the problem then I'd try cranking up the voltage a bit to achieve more stable clocks. (If it flickers when overclocking to 801MHz, then its the above problem)

make sure overdrive is disabled in CCC.

it will cause flickering if you try to leave it encabled, and use another OC program...

I don't wanna hijack this thread (sorry redface.gif) but I have the exact same problem with my 5870 and I have tried many different overclocking utilities (always with CCC overdrive disabled) and as soon as I press apply the flicker starts. Same thing as OP never in games, only in desktop and browser. I can even downclock and it will do the same thing. So I uninstalled all of the overclocking utilites I had and reinstalled video drivers... then proceeded to try downclocking using the CCC overdrive to rule out stability issues and still, I get the flickering as soon as I hit apply. mad.gif

Yes the first one must be it, because I have and overdrive disabled and whenever I change the bit color or whatever my screen goes back to normal.. Is there another fix because I don't want to do that every time at startup.
Thanks
