Hey,
Right now I'm running 12 rigs under Claymore miner, and expanding.
8 rigs with 7x RX 470 GPUs.
2 rigs with 6x RX 470.
1 rig with 6x GForce GTX 1070.
1 rig with 4x 1070 and 1 1080 Ti.

I have some Qs.

2 for now:

1) My rigs with 470s just show fan and temp for GPU0. In remote manager it's the same.

2) the GPU hangs in OpenCL call error. For what reasons that may be? So I fix it. I got it a lot under Eth+Dcr. Now on only Eth it's far far better, but I still get it time to time.

Thanks
