I got 3.7GHz out of the box with 1.45v. http://img396.imageshack.us/my.php?image=940oc2kx7.jpg I am overclocking using AOD at this time. I am going to find my max with it. My first crack @ 06 with HD 4870 1Gb Crossfire is 20235. http://service.futuremark.com/compare?3dm06=9560945 I'm using the old 8.10 driver because it is the least problematic. More results in a bit. EDIT: If I set 1.55v in the BIOS I can run 3.9GHz with AOD. I'm not sure I want to do that on air. 3.7GHz is the limit with 1.45v for me, so it looks like I made a good guess there. http://img181.imageshack.us/my.php?image=940oc3hr6.jpg I am going to be working on 3.9 and see if I can figure out a better way to do it.
