. your work truly is very much appreciated and i am willing to try this but not until we know that it works
two points Ambient temps but most importantly Case Air flow.
After that if it is clocking down you probably need to up the thermal target threshold on whatever OCing program you are using.
Or you could be experiencing a micro crash where it is not quite to get a black screen and the card recovers by downclocking meaning your card might not downclock if you have a OC target of 1280Mhz

lol if it helps I had 1280 to 1300Mhz depending which drivers I was using then I got the hotwire going and hit 1437Mhz Edited by feznz - 3/29/14 at 1:17am
