Ati and nvidia dont work with the same platform.
Thanks for the fast reply!!
Now i'm using 2 old card: nVidia 550Ti + AMD HD5670
they work with no problem, i use ccminer(trupov version <3) and sgminer 5.6.0 general.
I'm mining x11 with 800 khash + 300 khash if you need support i can give you. I'm using windows because more simple overclocking and get miner work.
Why you say that i can't mine with ATI + NVIDIA? With the rig is different? I mean, run 2 ati and 2 nVidia is different that run 1 ati and 1 nvidia?
If the card use the same driver version where is the problem? If i get two 460 but different model i will have error?
