anyone experiencing fluctuating hash rates with these F16's? Not sure what could be the issue but im mining on Eligius and my 7 miners are fluctuating from 33-45Gh/s, I'd like to keep them more stable at a hash rate of 40-45. Could it be a power or cooling issue, do they run more stable at lower hash rates? Or could updating firmware fix this?
These guys are very temperature sensitive, and CGMiner triggers a thermal shutdown at 53.5C and restarts at 45C.
What temps are you running at ? I suspect you're cycling, which might explain the fluctuation.
FWIW: I've had mine running solid for a few days now and they've settled quite nicely. One box fan blowing down on two wire racks housing these guys, with another floor fan blowing across them to keep 'em ventilated.
