Mining w 5850, 6770, 6850

[bitbanker]

Hi all. I've been mining for about a year. Just configured my second box. Having some issues w hashrate - hope you can help me out.

I started my second rig w a 5850 and a 6770 - was getting good hash rates. When I added a 6850, the hashrate of the 6770 (I think) dropped to a measley 1Mhash/sec! I'm running Win 7 64 bit w GUIminer. Anybody else experience these kinds of issues?

Thanks in advance.

actually looks like its my 5850 hashrate that has dropped to 1MHash/s and the 6770 is showing a hashrate greater than it should be able to acheive. Utterly confused. Help!

That sounds strange :l

Checkt the CPU load? It's not at 100%?

CPU affinity is set to 0% in GUIMiner - I assume this means no use of CPU (AMD Sempron)
