Posted this in the newbie forum first but got no replies.
I'm currently running my HD6850 at 925/1150 and I get 230-235 Mhash/s. If I lower the memory clock using MSI Afterburner, my hash rate drops correspondingly. If I go all the way down to 300 Mhz, my hash rate drops to around 160 Mhash/s. I have tried tons of different memory clocks in steps of 50-100 between 300 and 1150 and a higher memory clock always gives me a significantly better hash rate. What's up with that? Seems like I'm the only one experiencing this problem.
I use Diablominer with -v 19 -w 128 (gave me the best performance) and -f 30 (so I can play games if needed without closing my miner, when not playing games this setting does not affect my performance).
Anyone know what's up? I'd like to be able to underclock my memory without destroying my hash rate.

I've been mining an average of 20 hours a day at full capacity (220-230 mhash/s) for about 10 days now and I'm only at 0.9 BTC. My average share per unlocked block is ~0.0027, which is around 1/18000 of the reward. My rig has around 1/8500 of the pool's processing power. What's going on here? Something seems to be cutting my rewards in half, this is WAY lower than expected. Is this pool biased towards more powerful miners? I feel like I'm being scammed here. A friend of mine mines at over 800 Mhash/s on BTCguild, a little less than 4x my speed, and he gets around 1-1.2BTC per 24 hours. I'm very lucky if I can get 0.15 BTC in 24 hours, usually closer to 0.1.
I plan on moving to a different pool after I've reached 1BTC, hopefully that will fix the problem, but I'm wondering if anyone else has experienced this.

Can't post in the hardware section yet..
