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
Swapping PCI connection from 1 to 2
Swapping riser to GPU connection 1 & 2
Disconnecting working GPU and plugging non working GPU (1) into slot 2 on mobo
Swapping 2 with 6 And disconnecting 6
Swapping riser to GPU connection between 2 and 6. Leaving 6 disconnected
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.
