Title: Computer locking up with 2x msi 6950 Post by: deanorn on July 15, 2011, 01:11:37 PM Hello, I'm new to Bitcoin mining and was hoping someone could help me out with this problem. I have 1 computer that has 2 of the MSI 6950's in it and if I try and do something while its mining the computer usually just locks up. I'm running Windows 7, with the 11.7 drivers, using the Guiminer. I'm not sure if there is a flag or something I need to put in to help this? And I don't have the video cards overclocked or anything.

Set the following: In the ati control center -> performance -> graphics overdriver AMD Overdrive: enable (ticked) Power Control Settings: +20% Enable Manual Fan control: enable (ticked) set fan speed to 80% Click apply. I suggest you use cgminer.. seems to be pretty well optimized for 6990/ 6970/ 6950 http://forum.bitcoin.org/index.php?topic=28402.0 start cgminer with a batch file (runcg.bat) like this: Code: cgminer.exe -o http://ozco.in:8332 -u username.1 -p password -I 8 Title: Re: Computer locking up with 2x msi 6950 Post by: deanorn on July 15, 2011, 02:35:17 PM Thanks, I'll try that later today.
