I have (2) Sapphire 5770s running with no voltage changes (can't seem to change them in overdrive or afterburner).  I'm running current version of CGMiner, aggression at 9.  I'm able to pull memory at 300 for both, OC to 1002 on one, and 992 on the other.  I think bus voltage begins to sag and generally the second GPU drops.  Able to pull 232 & 227.8 for a combined rig total of 459.7MH/s!

Any word on stats?  I'm loving the pool, just would love it even more if I could see how I stack up.  Also expanding lifetime stats to see maybe last 1 day, & 7 days would be nice too.

They are 'buyers' but they aren't buying, they are effectively backstopping.  The price is sliding, so is the support.  This is also why there are big swings, people are looking for the bottom, but the buying bottom is sliding to find where the 'actual' buyers are.

Good post here on cost efficient rigs.

I'd like the chance to get whitelisted.  I've been reading on the 100% CPU usage issue, and would like to post my findings, but being a noob on the forum, can't.  Thanks.
