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).

I had a similar problem where Windows 10 wouldn't detect my 5th GPU. Try uninstalling your graphics drivers with DDU https://www.wagnardsoft.com/content/display-driver-uninstaller-ddu-v17072-released, and then reinstalling them.
Try 5 card is it not working change motherboard.
As much as I know, the H Series motherboard has a history of being a pain in the ass to get even 6GPUs detecting and working.
Anyway, try GEN 1 and give nvOS or smOS a try. Just burn the image in a 16 GB USB Stick and see if it works on Linux rather than windows.

Hey guys, so I recently built a new mining rig and am having difficulty having Windows detect more than 3 GPUs. I have some steps I went through to rule out that it wasn’t a hardware issue.
There are 6 GPUs (1070 hybrids).
O- denotes the GPU is working
X- denotes it is not working/unplugged
I started with
OXOXXO
Swapping PCI connection from 1 to 2
OXOXXO
Swapping riser to GPU connection 1 & 2
XOOXXO
Disconnecting working GPU and plugging non working GPU (1) into slot 2 on mobo
OXOXXO
Swapping 2 with 6 And disconnecting 6
OXOXXX
Swapping riser to GPU connection between 2 and 6. Leaving 6 disconnected
OOOXXX
if you guys have any idea what’s going on it’d be much appreciated. I have Win 10, 4g encoding enabled, and I have three options for link speed, all turned to 2 gen. Mobo is ASUS prime h270 plus. Two EVGA 850 G2 PSUs. I have been able to get a 4th GPU present I device manager, but it had an error code 43. I also got it to work at one point but had an error code that required a restart which ended up turning it into an error code 43 after the restart. It also worked at one point, didn’t show in the miner, then got error 43 and drug another GPU into error code 43 along with it, so I had two working GPUs and two with errors.
Thanks in advance.
