Hi All,

Newbie post - have done some searching but struggled to find an answer to this one.

I have been mining alt-currencies recently with a HD6670 just to learn the processes etc, used many pools and both GUIMiner and GUIMiner-scrypt worked well for me.  Was able to get around 100khash which is supposedly pretty good for that GPU.

Anyway, I rebuilt my rig yesterday and installed a HD7970, so am getting a much better hash rate now!  I put the HD6670 in PCI-E slot #2, and Catalyst shows both cards (however the HD6670 comes up as "disabled", even though in device manager both cards are enabled and drivers loaded etc).

I have run various combinations of GUIMiner / GUIMiner-scrypt, and no matter what I do I can't get the HD6670 to accept shares any more.

It connects to the pool, generates a khash rating, but even after 10 hours doesn't mine a single share, meanwhile the 7970 is chugging along nicely.

Any recommendations on how to correct this would be appreciated!

Thanks.
