Welcome to my new series where once a week I will feature a build from one of my community members.  Parts list, cost, any troubles if they plan on building more. ect.  With that lets get it started.

This weeks feature build comes from Rob Lords.  Rob is not new to the computer world as he has been dealing with Enterprise Servers for 10 years.  But this was his first mining rig.

“A question that I frequently get from people is why are you building a mining rig now? And my answer has been would you rather buy bitcoin at $20,000 or ~$6,000? Its been something that I’ve wanted to get involved in for a while and for me right now is the perfect time to dive in. People are turning off their mining gear and selling, which for me is somewhere near the bottom of the current bear market. This has given me a great opportunity to pick up some discount equipment and my build is mostly made up of second hand kit.”

The Build

  • Motherboard — ASUS PRIME Z270-P ATX Motherboard — LGA1151 Socket
  • CPU — Intel Pentium G4400 3.3 GHz Dual-Core
  • Memory — Crucial CT4G4DFS824A 4 GB
  • GPU — 1 x Radeon RX 570 8192M, 1 x Radeon RX 580 8192M, 1 x Radeon RX 580 4096M
  • Minercase — 6 GPU frame with PICe risers and fans
  • PSU — EVGA Supernova 850w G3
  • Storage — 32GB pen drive

Total Cost of arount $1200

Current daily profit at .10c per KWH $2.30

ROI Time 521 days (Side note, Rob is in the UK and there is quite a mark up compared to the US)

Rig build

“The building of the rig wasn’t overly complicated. I’ve been dealing with enterprise level hardware for over 10 years. So it was a case of fitting everything into its correct place.”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Rig Configuration

This is where Rob starting getting his hands Dirty

“The rig configuration was where I started delving into bits I hadn’t done before as they were specific to mining. I first started running the monitor off the onboard graphics as I was planning on using Simple Mining. I fired up the rig and went into the BIOS first off and set about updating.”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

“Once this was done I rebooted my machine after saving the settings and inserted my USB drive I had flashed with Simple Mining using Etcher. The only configuration I needed to do with this was to insert my email address in the config file on the drive so the rig would be registered to and managed by my account on Simple Mining. “

It’s Alive!!

 

 

 

 

 

 

 

 

“I was a bit disappointed with the hashing rate straight out of the box. I had read that some people experienced this too whereas other had not. At this point I left the rig running for 24 hours to make sure all was okay before looking to BIOS flash the GPUs.”

Bios Flashing

 

 

 

 

 

 

 

 

“So the next stage was to get the GPU’s flashed. I had looked around and the initial information I found suggested I would need Windows to do this. For me this was a pain as I’d need to install the OS and get all the drivers etc set up. Thankfully I stumbled across Hive OS. I’ve found this to be really easy to use, to flash and over clock with. I also think the interface looks a lot better than Simple Mining and its also free to use up to 3 rigs. Being able to flash the BIOS by the web interface was a big win for me. I used Polaris to modify the BIOS on my cards. The only thing that needs to be adjusted is the timing strap. Everything else can be done via over clocking. I flashed a new pen drive with Hive OS using Etcher again. This time I did not need to set any config as you add the rig by inputting the ID and password you generated on the Hive OS site on first boot. I also had to change my first GPU to be my primary display in the BIOS and this is a requirement of the OS + VNC. Once booted I went to the web interface to input my mining config and to flash my GPUs. Each card needs to treated individually for flashing. Rinse and repeat.”

(Full tutorial can be found in Robs Article Below)

The End Result

“So as of now I have fully operational 3 GPU rig running at ~91 MH/s which took me in all approx. 20 hours to get up and running. Its been a great experience and will be looking to add more cards if they are the right price.”
