Played with mem clock speeds. 350 saw no improvement, but 600 to 1050 saw a ~.5 Mh/s improvement, but still not enough to get me back the 2 Mh/s I lost.

Work size of 256 dropped off another few Mh/s, so that definitely didn't help. It seems like 07/03/2011 is the winner for me! =)
Thanks for your efforts though, I'll definitely keep testing and see if the newer kernels can return to the 07/03/2011 level.

I sold a game voucher for DiRT3 on Reddit's BitMarket. Great experience. Now I just gotta find more stuff to sell! =)

I just completed my first trade for Bitcoin. Have to say it's way cooler knowing that I got 1.5 BTC instead of ~20 USD. 

Just wanted to say thanks for the hard work, but today's (07/06/2011) kernel dropped me by about 2 Mh/s.

07/03/2011 got me ~300.8 Mh/s, but 07/06/2011 won't go above ~298.5 Mh/s.

I'm running on a 6870, Catalyst 11.6, SDK 2.4, and using the following: BFI_INT VECTORS AGGRESSION=13 WORKSIZE=128

Card is clocked at 960Mhz core, and 300 Mhz RAM.
