I don't know if AMD overdrive is like this for everybody but the range I have to overclock is limited and I can't under-clock my memory either.  I'm happy to be getting 350 Mhash/s but I'm sure I could be getting a little better.

Card is a dual fan gigibyte 5850 oc.  Brought clock from 765 to the max... 920 easily. 

I don't know if I need to flash the bois to allow for higher clocks or just use different program?

Just got this card in the mail this morning :exited:
