6770 crossfire with 5770, 5770 doing all work

post #1 of 3
Thread Starter 
just got a sapphire 6770 to crossfire with my asus 5770. Problem is that when i play games (any game) the 5770 is doing all the work and getting hot (fan runs at full noise after a couple of minutes) Have used gpuz to check whats going on and while playing a game the 6770 spools up to full speed on the clocks (gpu and memory) but then drops back to idle while the 5770 stays at full speed and does all the work. does not really make much sense to me as the 6770 is the first card and has the monitor plugged in to it. Have installed latest drivers for both cards.

Try flashing it to a 5770 bios.

Problem Solved. Did a fresh install after using driver sweeper and now it is running properly.
