Blank screen after overclocking 5770 crossfire??

post #1 of 6
Thread Starter 
After raising the clocks of my 5770's from stock to 920/1335 and pressing OK, I'm immediately met with a black screen.

I can't do anything, and so I'm forced to reset the computer.

Once I return to Windows and check CCC, the clocks are returned to stock.

What's happening?

One or both of the cards may not overclock well. Try overclocking each card individually to find out which one is causing the problem.

Does it matter if they are both different clocks? Doesn't one scale down to match the other?

Ensure power control settings is at 20% and try overclocking only 20Mhz at a time.

Not with the 5XXX series. It still does with older series I believe.
