thanks, this setting works for me, but only nets about 71 Mh/s here, however no increase in power consumption (still only using ~70W).  i'm using an ASUS EAH4850 @ stock voltage (1.123V i think)

that's for sure... even at just 71 Mh/s and manually setting the fan to 100% the temp is still 87.

i thought it would be nice to max out the existing hardware i have w/o investing in a higher-end card, but it's looking like there isn't much interest in this card anymore.  maybe i get 0.07 BTC/day from its mining...
