Thanks for the help guys one problem down (replaced the mobo) but now I'm running into other problems.

I'm getting some issues when I install my 5th card. When 4 are seated I get solid 500 hash across the board for each 1070 on Zcash. But when I ad a 5th one GPU 0 sits at 480, then 1st is 430, then 2nd is 240, then 175, then 134. I also can't touch one of the cards in afterburner when 5 are in. After a while one of the cards fails and then I get an error code 43 in device manager. I restarted my PC and received a BSOD with an error code Nvlddmkm.sys. It restarted itself a few times then I got back in and checked device manager and now the 5th card has an error code 43. EWBF miner is also crashing after 2 minutes with error "device 0 thread exited with code: 4" with the screen freezing.

Anybody know whats up? Any help would be amazing! I'm going crazy with all these errors.

Win 10, MSI Z270 SLI mobo, 6 1070 GPUs, and 2 850 G2 EVGA PSUs (all brand new).
