I have two 5850 and one 5770 in my BAMT rig at the moment. The performance I'm getting is quite sluggish.
5850 1: 845/150 MHz, 303Mh/s
5850 2: 940/150 MHz, 324Mh/s
5770 1: 930/280 MHz, 215Mh/s
BAMT is using the default miner, phoenix I think. I've set aggression to 11.
I used to get 730 MH/s out of the two 5850 cards alone when they were in my Windows 7 workstation running cgminer, using the same clocks.
What do I need to do to speed things up?
Will using cgminer instead of the default miner make things go faster, or is this a driver/software version issue?
in general cgminer will sometimes give slightly better rates than phoenix, but sometimes not, depends on hardware and settings. phoenix2 gives me slightly better rates than either of them, but I have limited hardware to test on so might just be me. in any case the difference is a few mhash, not the difference you are seeing.
there are several kernel parameters you can adjust in the default miner. probably just need to experiment. you should get similar performance regardless of the miner you use.
