Hello again after a long time
I’m glad that instructions I prepared helpd most of you. I wish I could help more for recent posts but I’n not using Asrock pro H110+ anymore. 2 months ago it’s burned One of PSU cable had faulty and it burnt both motherboard and CPU. Other components were OK (SSD, RAM).
So I had to buy new mobo.
Asrock was my first mobo to start mining. I had chosen it becaus to reduce initial cost like buying 1 CPU, 1 SSD, 1 RAM etc instead of 2.
But later I saw it’s not a good idea. 6x or 8xPCIE motherboards are far better than 12x, 16x or 20x PCIE motherboards.

Most important aspect is less operation down-time. If 13x mobo went reboot, you lose 13 GPU’s operation. It’s really big loss when you try to tune your GPUs. Every reboot means you restart all 13 GPU and no mining at all during this restarts. But with a small motherborad you lose only 6 GPU time.

6xPCIE mobos has simpler operation. Less cables allow easy intervention if you need to change something, for replacements or swaps. And easier troubleshooting.
So when I set my second rig I went for Biostar with 6xPCIE slots. And for other rigs I added were either Biostar or Gigabye motherboards. All are working good so far with less down-time and with very easy operation &maintenance & interventions.
After burnt AsRock, I bought a new Biostar mobo with 8xslot. It’s good as well.
I have 7 rigs with 39 GPUS since January 2021, (see the picture below).
The last Biostar mobo with 8xslots, I only could fill 3 slots and 5 more slots to go to make full rig.
All my GPUS are RX5700 XT with different brands, mostly Sapphire and Gigabyte 5700 XTs.
Also I have 3 Asus 5700.
My total minging hashrate is 2.06 GH/s with power consumption of 3400 W
Avarage hashrate per GPU= 53 MH/s
Avarage watt per GPU= 87 watt
My total investment is (includes everyting) ≈ $25 K
From Jan to end of May I mined around 13 ETH and got $42 K (avg. 8400 / month)
In this period, my total electric bills were $1700. Monthly average around $350
