Hey guys,
I just started mining this week with two rigs, one dual 6950 and one dual 5850. I'm using GUIminer with poclbm on Windows 7 64bit, with the latest catalyst drivers. My mhash readouts on both GUIminer and the BTCguild stats page total at over 1100mhash/s, which according to the simple bitcoin mining calculator (
http://www.alloscomp.com/bitcoin/calculator.php) should be yeilding 0.71 coins per day. But my 24-hour rewards count on BTCguild for the past 3 days bas only been 0.35 coins per day.
Help
