It's kinda weird, on my other rig also crossfired 5850s although both non reference compared to the other, they go up to 900 on GPU core. I'll see what else I can find. Maybe yeah you can up the limit to like 1000 maybe. Because my 6850 can go up to 1021 on GPU core. Thanks a bunch!
Eh, so does setting clocks above 775 work on 1.6?

It can't detect temperatures. The rest works fine, thanks. Btw there are afterburner's temps in tray.
ihaiuhaiuahiau

Yeah, check "Pause mining when..." It enables temperature monitoring. Otherwise temperatures show up as ?.
true... thanks =)
