Just some pics of what I got. It's not of idle or load. Just screenies of overclock :p
Looks like I could get 4.1Ghz on 2 cores, not just 1. No real point in going further since I could not get 4.2Ghz on 1 core.
Just some quick info. On my 4830 I usually OC to around 670Mhz core, with these temps I got 750Mhz but no serious stressing though just 100sec of occt with no artifacts. Still not too bad there could be an extra 75Mhz on the core if temps were better.
