I'm using linuxcoin since I'm a newbie into this mining realm. Anyways I'm running the polcbm (however you spell it) miner. I have 2 6950's I get about 330 mhs out of them when they run alone, but when I start up my 2nd one (the one the monitor isn't hooked up to). It will jump around alot going from 330 to 300 to 150 to 250. But when I stop my first card, it'll just jump up and do steady 330 mh/s.
Any Ideas? I am new to linux but I've learned alot in one day.
Go easy on me.
Thanks
