The 5850 Overclock thread, post your overclock settings and benchmarks.

Tested for 11 hours with Kombustor at max settings at 900\1175 with 1.125v. After that, I dumped my bios, modified the 3D clocks with RBE, and flashed it back.

Currently running 900/1250 @ 1.125V on both cards (haven't tested them individually) via BIOS flash. I'm surprised by how far the RAM clocked, but I saw no performance degradation so I can't see that ECC is kicking in. I've actually had the RAM up to 1375MHz before the cards crashed, so I think I gave myself a decent amount of headroom. However, I do plan to test the RAM clocks more thoroughly once I get some time.

I couldn't go above 1175 without Kombuster crashing I haven't benchmarked at all, so for all I know, 1175 is slower than the 1125 it started out at. I guess I should fix that
