Hi guys, Im having some problems with a 6990 i got from a friend
msi hd6990 (stock clocks, bios switch in default position)
950w PSU ( basic, generic, whatever you want to call it, its crap
http://www.maplin.co.uk/950w-g7-extreme-modular-atx-psu-517553Win7 64bit
catalyst 12.8 (tried 11.4 first, would not install without failing)
bitminter miner
running bitminter or phoenix or other miners results in:
After i start mining i can get a hashrate of about 100 on GPU 0-0 and 3-400 on 0-1, should these not be around the same? Is my PSU not good enough to handle it, have i messed some settings up?
So im getting say 500 mhash/s from one 6990? That cant be right, can it? GPU-Z shows me that the crossfire used by the 6990 is active and that both GPU's are enabled.
