My only other guess is that your card is throttling. Can you get GPU tweak and see if your speed stays at 1000MHz or close to it? If it is dropping by a fair amount you may need to turn up the fans higher. Yes it sounds like a hairdryer but its the only way to keep temperatures in check.

Watching at 2 rigs with same hardware, one is on win7 (catalyst 13.9) and another is win8 (catalyst 13.11)
Conf. files is same
Windows 7:
752-755 kh/s
752-755 kh/s
752-755 kh/s
649-666 kh/s

Windows 8:
753-756 Kh/s
753-756 Kh/s
665-720 Kh/s
753-756 Kh/s

Looks like windows8 is better a litle bit :) Will install win8 in first rig to, on Sunday. And will post update.

In the test is that the vegetable oil is better than mineral oil coolant and air.
As vegetable oil is not derived from petroleum, does not attack the embedding in plastic components and oil components. Then it can be removed more easily the vegetable oil.(isopropyl alcohol)
The components are not going to ever wear, it is impossible to wear submerged in oil.

;D idea…

modifying Split Air Conditioner and Pump… ;D

I do not still manufacture my devices mining…
but …

I think it is best to cool with vegetable oil, and cooling the water in heat exchanger …

[b]My idea is to use a water pipe inside the tank with oil, and this cool with any automobile radiator and electric fan 12V respective[/b]

JPMorgan patents Bitcoin-like payment system.

"JPMorgan Chase has patented a digital payment system that could rival Bitcoin.

JPMorgan has also patented payment software that would latch onto your Internet browser and allow you to shop without pausing to fill out forms with personal financial information. And with what the bank calls its Internet Pay Anyone Account, moving funds would be anonymous and as easy as sending an email."

[quote]Gridchip GC3355 can have BTC only at 5.30W, or BTC+LTC at 4.2W, [b]or LTC only at 0.44W.
59.6Kh/s at 0.44W is 135kh/s per watt[/b].

[b]Is 45x more efficient than a HD7950.[/b]
2250 Gh/s is so fast that i think this document have a mistake, must be 2.250 Gh/s instead.

And is possible to make a coin ASIC, FPGA and GPU proff, but i don’t know if is possible for ASIC and FPGA proff only.[/quote]

GC3355 chip is 70Kh/s . power is 4-5w.

36 chips would deliver 2,520 kh / s with a low consumption of only 160watts.

That’s good! ;D
