Currently in the midst of building and testing a GPU mining rig which is AM4 based which allowed me to test parts from my currently downed workstation, leading me to call the time of death on the old processor.. So far I'm pulling over +400Mh/s with 5 Sapphire RX 580 cards, which consist of various 4GB/8Gb Nitro+ and PULSE series cards, I shit you not. This was achieved using the recently released AMD optimized miner that goes by the name of mkxminer. You can check out Mkxminer here: MKXminer Bitcointalk.org Thread

The Parts List
This is a prototype experimental mining rig, not one of those fancy professional deals you see all prim and proper with all matching parts, meticulously constructed frames and well thought out layout. Nah, this build was the first time I ever made a rig, and the hope was to make it self contained and stack-able to create similar mining units in the future if it's successful. A spare PSU I had kicking around seems to be working for the 5 cards I have currently running but about to get 6 going today if all goes to plan.
$1896.86 - 6 x Sapphire RX580 GPU (Mix of Nitro+ & Pulse 4GB/8G)
$102.99 - 1 x Biostar TB-350-BTC Motherboard (6 PCIE Slots)
$142.99 - 2 x 4GB G.SKill Ripjaw V RAM (3200Mhz FSB)
$125.99 6 x PCI-E Risers 16x to 1x
$149.99 - 1 x Ryzen 3 1300x 4 Core 3.5Ghz CPU (With Cooling Fan)
$9.99 - 1 x Thermal Heat Paste
$229 - 1 x Corsair RM1000i PSU (1000w Digital)
$20 - 1 x Shitty Wal-Mart Shelf
$??? - ? x Random Salvaged Shit
Total Cost: ~$2677.81 CAD
The Hashing Power
The rig seems to be pulling anywhere between 400MH/s-1000MH/s on the pool I'm mining on. As for wattage that is well over 1000w with my guess closer to 1450w but yet to get a kill-a-watt and see what the actual power draw is on this beast. Will get a nice spreadsheet going and start keeping track of the daily earnings of the rig shortly.

Such pretty LED colours that alternate and entrance me if I let myself stare too long

The main PSU has a monitor. Here It's showing around 900w draw..
It runs higher than this now though
Plan to open up the top section housing the 4 Sapphire Nitro+ cards to try and get the heat down a bit and allow for greater speeds. In the next little while I'll be tuning the machine to use less energy and get optimal hash per watt. Stay tuned for updates on my prototype mining rig later on in the week. Maybe it works flawlessly, maybe it lights on fire!
Only time will tell...
