Optimize hashrate for 5850

[heinz]

0.96 volts(cgminer shows 0.959),  835 core, 150 mem, 344 Mhash ( a grand total of 80 watts per 5850)

This is what I have installed and it also gets rid of pesky 100% cpu bug.

I got a dud 5850___and 2.5 SDK.

Find the failure. ^^

I was under the impression that 2.5 worked just as well as 2.4. It was 2.6 that gave ~10% lower hash rates. Also, what does the SDK have to do with not being able to OC? My 5870 and 5830 OC to 960 and 940, respectively. My 5850 only goes to 875.

I just mean your hashrate buddy, can be 350mh/s @ 860mhz.

Ya you're totally right. I was at work and got the numbers wrong. I just checked and it's doing ~354MH/s @ 865. Damn you were pretty close!

I just switched from BAMT (using Phoenix2) to cgminer (with the default kernel) running on the Peppermint Two 64 bit edition linux distro. I'm seeing ~2% increase in efficiency and I can clock my cards a bit higher than I could with BAMT. The difference could be due to switching from 32 bit to 64 bit, but whatever the reason, it's a nice little improvement for my 5850s. The desktop is also much more usable (much quicker) than it was with BAMT.
