Hi,
I'm not sure whether this thread relates to the problem I'm having but I'm almost at my wits end so its worth a try, I hope someone can help.
I've just got myself the new 5870 and when AMD Overdrive is disabled the card works fine but the moment I enable it I get like a periodic flashing on screen which looks like another copy of my desktop every half second or so, it doesnt matter whether I dont even change the clock speeds, the moment the tick box is ticked and i click apply i get this problem.
When looking at GPUz I can see the clock speeds change to stupid amounts 157 core 300 memory when default is 850 / 1200 and the voltages drop to silly amounts aswell.
I was thinking maybe it was something to do with powerplay as when overdrive is disabled the core and memory does drop every few seconds to 400 / 800 which i assume is a power saving feature.
I have tried disabling powerplay via the xml profile hack found on another site but it still gives weird clock values.
My last trail of though is maybe a power supply issue?
I have the Antec NeoPower 650w
details can be found here

and here is a screenshot of the weird clock values when overdrive (or any overclocking tool) is used.
hope someone can help
