Bitmain Antminer L3+ review

Bitmain Antminer L3+

I got 2 new Antimer L3+ ASIC miners and I’m really happy about the quality of these miners. Setup was really easy and performance was as good as promised. Power consumption is exactly 800W from wall with Bitmain 1600W PSU.

I’m using NiceHash as pool and it’s reporting about 950-1100MH/s with these 2 units. Profitability is about 0.0172 BTC/day ($75.50/day or 62.60€/day).

First miner was turned on 5. September and second miner day after as you can see in below picture.

How to setup:

  1. Connect all 7 power cables
  2. Connect ethernet cable from router
  3. Turn miner on
  4. Search miner IP from network
  5. Open miner management console in browser
  6. Log in (root / root)
  7. Change root password
  8. Optional: Change miner IP to static
  9. Open Bitcoin wallet if you don’t have yet
  10. Generate pool stratum address
  11. Change pool address (all 3) and use your BTC address as username (no need for password)
  12. Monitor performance and reliability
  13. Enjoy profits!

 

GPU mining hardware

Listed below is the hardware you will need to assemble GPU minig rig. Basically, you are building a custom open-frame PC, but instead of one or two graphics cards you will be adding up to 9 GPU’s.

  1. Power Supply (PSU) 1
    • You should buy an efficient 750-1200W modular power supply that will save you over the long run in electricity costs. Look for Gold or Platinum rated (as opposed to silver or bronze). You will be using this PSU to power everything else than GPU’s.
    • Recommended models/brands:
      • Corsair
      • EVGA – 750G2
  2.  Power Supply (PSU) 2
    • Second power supply should be 1200-2400W server PSU with breakout board and cables. Power supplies capable of 1500 watts output can sell for hundreds of dollars. You will be using this PSU to power GPU’s. Remember to buy compatible (C19) AC Plug!
    • Recommended models:
      • PSU Delta: DPS-2400AB
      • PSU HP: 40785-001, 438202-001, 437572-B21, 512327-b21 511778-001, HSTNS-PL33, 684529-001, 684530-201, 704604-001, 684532-b21
      • Breakout boar: X7BRK, X6BRK
  3. Motherboard (Mobo)
    • I’ve listed below motherboards that are compatible with at least 6 video cards. These are the mining motherboards that are used in large scale mining deployments.
    • Recommended models:
      • MSI Z170A
      • Asus Z270-P
      • AsRock H81 Pro BTC
      • AsRock H81 Pro BTC R2.0
      • AsRock H110 Pro BTC+
      • Biostar TB250-BTC PRO
      • Biostar TA320-BTC (AMD)
  4. Processor (CPU)
    • Pick any cheap Skylake Dual Core processor.
    • Recommended model (depending on motherboard model)
      • G3900 Skylake Celeron
  5. Hard Drive (SSD)
    • Pick any cheap SSD for installing operating system and your mining software.
  6. System Memory (RAM)
    • You don’t need a lot of system memory to mine effectively. I recommend just picking up a cheap 4GB.
  7. USB Riser Cables
    • These are to connect the graphics cards to the motherboard and allow spacing between cards for heat dissipation. These are necessary when building a rig with this many GPU’s. You should buy some extras because these are often broken.
  8. Expansion cards
    • If you want to add more GPU’s than your motherboard have pic-e slots you might need to add M.2 expansion card.
  9. Dual PSU Link Cable
    • If you are using 2 ATX powers supply’s you need to add link cable between those PSU’s. I recommend server PSU instead.
  10. Graphics Cards (GPUs)
    • Before AMD cards were the only choice to mining but in last few months Nvidia cards have become very popular. There is so huge demand for these good mining GPU’s that these are sold out almost everywhere and that’s why prices have risen.
    • Popular models from most powerful:
      • Nvidia GTX 1080Ti
      • AMD R9 Pro Duo
      • Nvidia GTX 1080
      • AMD HD 7990
      • Nvidia GTX 980Ti
      • AMD R9 Fury Nitro+
      • AMD R9 Fury X
      • Nvidia GTX 1070
      • AMD R9 Fury Nitro
      • AMD R9 290x
      • AMD R9 RX480
      • Nvidia GTX 1060
      • AMD R9 RX 570
      • AMD R9 280x
      • Nvidia GTX 980
      • AMD R9 RX470
      • AMD R9 Nano
      • AMD R9 RX390
      • AMD HD 7950
      • Nvidia GTX 970
      • AMD R9 270x
      • Nvidia GTX 1050Ti
  11. Custom Mining Case
    • I’d recommend to build your own mining rig.
    • How to video
  12. Operating System (OS)
    • simple mining os
      • Really easy to use and great developer!
      • Idea is simple: download for free my OS and write it to any drive: Hard / SSD / even USB drive. After that you just enter your email address in config.txt file and boot your rig. Login to simplemining.net dashboard using the same email and start managing your rig.
      • Download
      • Support
    • eth OS
      • ethOS is a free 64-bit linux OS that mines Ethereum, Zcash, Monero, and other GPU-minable coins. If you are using the Nvidia 1070 GPU’s I recommend mining on Windows 10, since Eth OS has some driver issues with Nvidia cards.
      • Download
    • Windows 10
      • Easiest for flashing GPU’s
