The Bitmain Antminer T21 is one of the best bang for buck mining rigs, and arguably the best value for a BTC ASIC miner, and we are even using this 3 phase BTC miner, as a 1 phase Bitcoin mining rig, let’s review the T21 and our Bitcoin mining profitability! Buy miners here -…

  1. The t21 gets 3610 watts. So i would have expected it to get maybe 3500 since you did a step down. But no way would the firmware be so efficient it would take it from 3610 to 2700. Maybe the 3700 and step down is from loss of efficiency from 3 phase…

  2. I love watching people tinker with things like this and take something that may not be necessarily useful in your current situation and making it absolutely rock. Altair's stuff looks great and I wish my power company would be reasonable and make it profitable for me to join you guys in this. I still enjoy watching you guys tinker and power up your mining empires though. Another great vid from the Vosk team.

  3. LuxOS has always been way off on the power consumption when ive used it. Did you happen to test any of the underclocks to see what this hashed at when under 3k watts? The 19 series seems to do extremely well when underclocked to 1800-2200 watts so im curious where the golden pocket for the 21 series is at.

    Personally I really like VNISH and it's super easy to install when using Awesome Miner.

  4. Does the efficiency improvement offset the reduced income from the extra fees? Can you do something at the router to block the "fee" mining and reduce the power consumption during the time the "fee" pool is running?

  5. I just received my 120v Urlacher S19k pro from Altair after watching your videos, and it isn't disappointing. I have a decent amount of spare production from the solar panels on my barn and garage, and it's humming along quietly pluggind in to a 120v 20amp circuit, hashing at 59.7TH/s, and drawing 1260w, for an efficiency of 21.1j/TH. The only issue I have with the setup is the Luxor OS misreports power usage at 1.62kW (probably because of the daughter board spoofing the 240v PSU), when in fact my wall plug meter shows 1.26kW.
