Title: Problems With 6970 Post by: Joshwaa on July 20, 2011, 02:24:09 PM Ok here is the deal and I need some help. Can't figure this one out. In my one miner I had a 6970 and a 5850 mining together and everything was fine. I switched the 5850 out for another 6970 and everything went down hill.
System : ASRock 1155 Extreme 4 P67 Intel i7-2600k Gskill DDR3-1600 2x4gb Crucial SSD 64G Diamond 6970 2G Ok when the 6970 and 5850 were in I would get 435MHash/s on the 6970 and 360Mhash/s on the 5850 (Very happy with that) However once I put the other 6970 in and took out the 5850 best I can get is 380Mhash/s from the two 6970. I have noticed in afterburner no matter what I set the clock to it jums all over from 800Mhz to 925Mhz and will not keep a stable clock. Also the mem on the cards can no longer be adjusted it has no effect. I am really at a loss. I reinstalled 11.6 drivers and full reinstall of afterburner. No effect. Please help!!!! Thanks Joshwaa Title: Re: Problems With 6970 Post by: TeraPool on July 20, 2011, 07:36:52 PM I assume you are running windows?
Please try to run linuxcoin - it is a linux operating system that is entirely built for bitcoin mining - it has all of the drivers and accepts up to 8 GPUs plugged into it by default. Try that first if you are having problems with windows, or any other OS for that matter. Good luck!
