Hi there, I set up bitcoin the other night using GUIminer and have been keeping an eye on things but the variance I am getting in MH/s is ridiculous. My setup is as follows,
GPU- 6850 x2
CPU- X4 955BE
running on win7
with one card enabled I am getting 180MH/s
with both enabled (as seperate miners) 130/130 (260)
however when I leave my computer and check on it later this has dropped to under 100 per card until I check on it. I have no power saving options enabled I am just turning off my monitor and leaving my computer running. So I have looked around and cant find a definite answer so I thought it best to ask.
1. Is there any way to get 200% with two cards running or am I missing some setting?
2. When left unattended why does the rate at which I mine decrease so fast, I mean 10 mins after I last checked on it, it drops again?
any help would be greatly appreciated, thanks
