About this model
The Antminer T21 is Bitmain's budget model from the new generation, built on the BM1370 chip (5nm). At 190 TH/s and 3610W, it delivers 19 J/TH efficiency. The T21 offers affordable entry into the new S21 platform while maintaining high performance.
Structurally, the T21 is based on the same platform as the S21 with identical hashboards and control boards. We repair the T21 at the component level: BM1370 chip replacement, trace restoration, VRM circuit repair, reflashing, and PSU repair.
Bring your T21 in — we'll restore stable operation with a warranty on completed work.
Common issues
Hashrate doesn't reach 190 TH/s — BM1370 chip degradation or calibration loss
One hashboard running unstable — localized VRM element burnout or trace damage
Elevated consumption at normal hashrate — domain failure on hashboard
Fan making unusual noise — worn bearing or foreign object
Unit hangs on startup — firmware crash or control board SD card damage
