I get 820kh/s on my 290
surely a 290x should be the same, if not higher? and you guys are saying 780 is high?
I'm getting 880 stable on my 290's

wow, is that temperature normal for a 290???
I'm not running anything above low 60's (10-270x's)
My 290 ran at 96C when mining at 820kH/s (the highest stable I could get, but then again my card seems to be a crappy one. Driver crashes alot when i stop mining and restart etc.)
Now it runs at 65C with watercooling and the same 820kH/s. If i increase intesnity the kH/s decreases. Sux...
im around 830 khash/s with my 290s on default clocks (947/1250). But the fan is running at 82% (around 4500 rpm), keeps the temperatur "cool" at about 78-80 degrees.
