Welcome to Miami!
Thanks,

I think I'll still with the 7950s as I can separate them on extender cables to dissipate heat better.

Thanks for the replies guys...Not sure who reported those hashrates to the litecoin mining hardware comparison wiki pages of 2200+ but sounds like it's time for a screenshot for comparison...

May the force bit with you.
I have 1, i can't get it to go over 1.15 without crashing. win 7, latest catalyst ver, reaper 13b4. cgminer just crashes all the time. I mostly do btc with it now I can get 1.3 -1.4 gh/s

edit: I didn't pay that much for mine. only 900ish.  Not sure worth it at that price.  Also they run HOT.

Do you still have it?  Did you try the settings in the hardware comparison guide?

If you still have it would you be willing to try it again with some settings I give you?  I don't mean to use you as a guinea pig, but if you can get it mining higher and I can verify if the investment is worth it we might both profit.

Welcome to Miami!
Just wondering how accurate the mining hardware comparison guide is on their estimate of ~2300 Kh/s for one of these?

At over $1,150 each it would suck if it didn't live up to its hashrate, but if it came pretty close it might be worth it on the power savings alone versus 4 7950s...

Anyone?
