Would prefer offers via PM (easier to find).
You're doing it wrong. You should have been averaging a little over 2MH/s.
It sounds like you are really underclocking them,. How much ram do you have? From my personal experience of running 3 different brands of 7950s I've found they all run at a different hashing speed. My Gigabytes are the quickest at about 650KH/s whereas my sapphires I can't seem to get them above 580KH/s. My VisionTeks are typically 600-610KH/s. I'm still tuning the VisionTeks. I'm pretty sure I can get more out of them.
I don't know what I'm doing wrong with the sapphires. I have 16GB RAM on all the boards. I didn't struggle with 8GB of ram on the board, but it did seem to help when I went to 16. 6GB was a no go for 4xSapphires.
My Sapphire 7950 pulls 650+kh/s.
