Throwing 250-300 mhash/s

Is that with a HD 5850 ?

yes, I'd either be mining or doing other stuff so overall electrical usage is negligible.

My HD5850 started stock at 260mh/s and is now running at 391mh/s Wink

Oc it !

Out of curiosity - how did you get the 5850 to 391MH/s? What's the voltage and GPU frequencies? And what software do you use and how many watts does it use?
I've found mine to be quite stable when undervoltaged to 0.975-0.987 and GPU at 775-785MHz (which results in 305-308MH/s). On the good side - power usage is pretty decent - 675W with 5 of them mining.

This can be easily done at stock voltage mem@150 core@840. You only need to replace cooling paste with Arctic silver. Usage is about 180... And I have tested your settings. I think you need batter kill-a-watt. I can't make it run with the usage that you reported last time... It uses about 120W+. If I remember correct you reported 85W.

Yup - idle wattage (with just 1 video card) is around 180-190W and with all 5 it is around 220-230. On full load it is 660-680 (depending on room temperature) -

which makes 305MH/s:

So - my calculations say that it's 90-95W per card currently. (and I had to move them to another room that's not airconditioned so everything is running a bit hotter).
