Which card are you using?
Some cards' firmware throttles the processing to reduce emitted heat, as already mentioned.

Perhaps the card is just unstable at that clock. Does Furmark or similar run without artefacts?
doubt it - it's simply a matter of when I increase the clocks, the Mhash drops o.O heat was at 74c
Anyone else had this? At around ~880 clock, the cards I have been using are pushing around 350Mhash. When I bump the clock rate up higher, say 900+, the mhash rate goes down (sometimes by nearly half).
are they being throttled down due to heat?
