trying to use dual miner with radeon 6970 and 280x together
catalyst 15.7

280x + 6970 = about 32mh, but rig is rebooting after 5-10 minutes
6970 single = no go
280x single = about 20mh

so is there any way for stable mining with 6970 ?

You have a hardware problem.
Im guessing your psu(s) have a problem.

You should note that Claymores uses more wattage that then other ethminers.

will check, but dont think so...1 PSU 800w powering MB+6970, and 1 PSU 800W powering only 280x

One of my rigs had this problem.. inspecting it i found out the mobo alone needed 450 watts ... so it had to get a supply of its own before that rig ran 24/7 with claymores. No probs with genoil.

I could run claymores for hours using -ethi 0 .. but that put performance below genoil.

Where on earth would motherboard dissipate 450W of heat?

I'd say swap cards, swap power wires. Total consumption should be around 500-600W.

And of course install 15.12 or its dll-s at least.
