Post Re: BitCoin Mining
I've been mining for about two months now. For the first month I was mining with 5 x 6970's and 3 x 6950's. For the past month two 6970's have been without a rig so they've just been sitting on my desk.

When you have a dedicated mining rig like the one my 6950's are in you can do alot to cut power consumption. The processor is underclocked and undervolted. The GPU's have overclocked cores that are slightly undervolted and the memory is running at only 500Mhz. It gives me about 2MH/s/W (power is .105/KWh). That's significantly more efficient than your 1.22MH/s/W and my power rate is much lower. I think that along with the size of my hashing operation is what is resulting in a higher profit. If you were to increase your efficiency you'd be more profitable. I expect my next mining rig to generate about 3MH/s/W.

makes sense... maybe i'll wait till the exchange rate go up to make more sense for me to mine, or just wait till my next CPU upgrade that's more power efficient than this power guzzling godzilla old fart.

new update: at 1200mhz core speed (HD7950), i clocked a 630mh/s. it's about two of my overclocked HD5850 combined.
