7970's supposedly loses efficieny above 1125

post #1 of 4
Thread Starter 
Im looking for the articles on this subject, there were a vieuw reviews where they tested minimum framerates vs several clockspeeds but i don't remember where. Could someone point me in the right direction please. I remember the average framerates went up with all tested clockspeeds but minimum framerates started going down fast after 1150.

I remember someone mentioning something like that in relation to memory speed, where after a certain point the higher frequency resulted in errors which in turn resulted in lower performance, until a certain frequency was reached where the memory was fast enough to compensate for this. I think this was in the 78** owners thread. Never heard it in relation to GPU core speed though.
