I cannot log in either thought it was just me, i use a unique password only for Mybitcoin.

I hope it will be up and running again soon.

 

I am limiting it but it does not seem to effect my hashrate as long as its set at 57% or so even if i drop it down too something like 20% i do not see any reduction in my hashrate with my two cards, i set it at 57% as at 58% it starts to use about 70w rather than 40w when at 57% mostly so it quieter although the powersaving is also good .
This is because i am still using my computer for search the web watching youtube etc when the two gfx cards are running and i the computer becomes sluggish if it was set real low but does not seem to effect the hashrate just the responsiveness of my system in general.

I think i have found a solution to this problem atleast on Win7, if you go into the advanced power settings in Win7 you can set the Maximum Processor State to say 40-50% and with my system
5770
5850
AMD Athlon II X3

Causes the CPU to remain at only around 40watts rather than 110watts as shown by HWmonitor program when mining with dual cards. I had to do some testing to see what was the optimal setting for me by adjusting the percentage until GUIminer was getting the highest MH/s but also before the CPU started to go above 40watts.

Hope that helps.
