So my 2nd rig is now running with 6 GPUs.

Rig 1 https://i.imgur.com/Q6kLeV3.jpg
Asus Prime Z270-A Motherboard
Corsair HX1200i PSU
Celeron G3930 CPU, 4GB RAM
(7) Gigabyte GTX 1070 Founders Edition

   CC: 200
   MC: 1600 (4608 MHz mclk in nvidia-smi dmon)
   pl: 120W

   945W at the wall

   ~220 MH/sec ETH (31.4 mhs per GPU, 26% over stock)

Rig 2 https://i.imgur.com/SUp7cj4.jpg
Asus Prime Z270-AR Motherboard
Corsair HX1200i + HX1000i (using Add2PSU)
Celeron G3930
(4) EVGA GTX 1070 FTW, (2) EVGA GTX 1070 SC

   CC: 1
   MC: 1100 (4353 MHz mclk in nvidia-smi dmon)
   pl: 125W

   885W at the wall

   ~180 MH/sec ETH (30 mhs per GPU, 20% over stock)


Rig 1 is nice and stable. It's been mining consistently for over 62 hours. Rig 2 is semi-stable: It's been running for just under 24 hours. It doesn't lock up, but I do get error messages from Claymore randomly that cause Claymore to restart on average of once an hour. I will try lowering MC to eliminate those.

I need to get a case built to improve cooling and to ensure these GPUs aren't at risk of falling over like dominoes. I had planned on working on that last weekend, but then I made the decision to build a 2nd rig so I held off. What I am thinking of doing is repurposing a 4' wide x 4' deep x 6.5' tall indoor gardening tent (similar to this: http://i.imgur.com/whULDww.jpg)and placing the rigs inside so I can keep the heat output under control and hopefully increase cooling. I'll have an exhaust fan sucking out air from the top of the tent, and passive intakes at the bottom pulling in cool air. I'll route a 6" duct from the exhaust fan to a window to blow the heated air outside (until winter time!) so that my central air doesn't have to deal with the extra heat I'm currently introducing. Rather than build a case/frame out of wood or aluminum I am thinking of using a wire shelving unit. I like the idea of building a nice aluminum frame, but I'm not 100% sure if I am going to stop at 2 rigs or keep going, so until that clears up I am not going to construct a custom frame.

As I was typing this rig 2 experienced one of the Claymore errors:

GPU 0, GpuMiner cu_k1 failed 4, unspecified launch failure
GPU 0, GpuMiner kx failed 1

WATCHDOG: GPU error, you need to restart miner Sad

Why are you running 7x cards on a single psu and 6x on the dual psu config? From your 'at the wall' readings I would think 1200W would be ok for each rig? Is there a reason why you went dual? Asking as I'm planning on running similar rigs myself with a single 1200W supply.
