2. ATI Radeon HD 5800 Series   (:0.2)
    engine clock 925MHz, memory clock 325MHz, core voltage 1.163VDC, performance level 2, utilization 99%
    fan speed 65% (2179 RPM) (user-defined)
    temperature 45.5 C

2 = 295 Mh/s

Number 2 (5830), forget what it is... xfd maybe.... very disappointing 925 is as fast as it will go and remain stable.

Hey stryker, looks like your #2 5800 is outperforming mine by quite a bit despite being clocked 25MHz lower.  Could you elaborate on your miners setup?  I'm on phoenix and posted the options I'm using in the post directly before yours.


Also, a general question for all who may read.  I have been decreasing the mem clock on this card and now that I am down to 550 from 800 previously my mhash rate is up from 287 to around 293.  Is this a benefit of the lower memory clock rate?  I was under the impression that a lower memory rate was just a measure to save wattage.
