Best,

I got a 5850 and a 6870 not working fine. 5850 is giving 150 Mhash, which is okay, but I know it can do way more than that. 6870 is giving 30Mhash, which I know there is something wrong. The previous owner said they should both working fine, and they were giving 350 and 250 at least. And he shown me the graph record as well, so I believe the graphics are fine, maybe problem with settings. There are two other cards working with them, both are giving good rates, I am using CGMINER, and I tried gui as well, same result. The 6870 is showing 300Mhz engine clock by cgminer, I think it is weird, but I can not change it. 0.5 BTC bounty for anyone who can help me out, first reply first served. THANKS!

I just brought rig but I can not start mining. The problem I am facing is the win XP can identify the card, but the GUI or CG miner can not. And the rig can not be booted into BAMT or Ubuntu with stick as well. At first GUI miner said can not find openCL GPU, later, after I updated all the drivers to be latest, such as 2.5 OpenCL, the GUI miner can be booted, but I have only one usable miner, which is the CPU. Help needed ASAP!!! Thank you guys.

We want to buy some rigs, the price we offered is 0.5$/MHash or equivalent bitcoin value, please PM for further information or large amount. East Coast US preferred. Thanks!
