the first tier starts off cheap at .13 up to 323kwh. that’s basically enough to power the LEDs on my electronics. now i’m on the .30 tier.

Here is an update for everyone:

My 6x Sapphire R9 280x are still back ordered no ETA
My 2x Gigabyte R9 280x Rev 2 are awesome but voltage locked…ugh

The gigabytes are running at 730 and 750 KH/s sitting about 80c in a rackmount chassis. I am planning on flashing each of the 2 bios to my power optimized settings so that I can control the voltages on the video cards. I don’t have power consumption numbers for these cards yet. As some of us mining on windows have seen, the first GPU in the set of GPUs seems to be running slower than everyone else no matter what. I run 1050/1500 on GPU 1 and 1080/1500 on GPU 2 both with a TC of 21105… GPU 1 can’t run at 1080/1500 at all. Another piece of that puzzle is that I use the same OS on all of my mining rigs…none of them work with standard TC settings for miners, when set to 8192 for 7970s or 24000 for 7950s I get low hash rates.

you can modify the voltage on those Gigabyte cards with VBE 7. i have 4 of them running at 1.05v and 1035 clock

electricity sure is expensive here. :(

and i hate these damn captcha thingies.
