i used atitool to find my max gpu/mem before getting a single artifact and it went to 834/994
so i edited my bios with RBE to 830/990
~830MHz is really good for an HD4870 @ stock volts. Most people need to overvolt just to get to that level. The memory OC is pretty turdy, but the gains are small as you get over 1GHz. Would be nice to see what your card can do with a little extra juice.

You're out of luck. You'll need to do some hard modifications to increase voltage for your HD4850. Sorry. :*(
