I'mcurrently running one at 1055/300

Overvolted to 1225mv

And fan at 100%

Maybe you just got a bad 5770? Sad

I run 2x 5770's at 970/300 each.

Each one is running 215 mh/s.

I use guiminer with -v -w 256

I use MSI afterburner, and made sure to set my fan speed to 100% all the time.

I changed the voltage up to 1174.

After all of these changes, my cards run around 67 C, are very stable, and I've had no issues what so ever.  It seems as though I get a lot of artifacts on my screens if I bump to 1000 mhz, and if I run the core clock at 1k for too long, my compy will crash.  970 seems very stable and it has been running this way for weeks.  I would be more than happy to help anyone get set up with their 5770's.
