About this model
The Antminer S21+ is an enhanced S21 with boosted hashrate of 216 TH/s at 3564W consumption. Its 16.5 J/TH efficiency is among the best for air-cooled models. Built on the same BM1370 chip with better die selection.
Structurally identical to the base S21, meaning identical repair procedures. We perform component-level hashboard repair, chip replacement, trace restoration, VRM circuit repair, control board reflashing, and PSU repair. Our S21 series experience allows us to work quickly and efficiently.
Bring your S21+ in for diagnostics — we'll restore stable operation at full hashrate.
Common issues
Hashrate fluctuates instead of stable 216 TH/s — partial chip degradation or unstable power
Unit freezes during operation — control board overheating or firmware crash
One board running at reduced performance — localized VRM element burnout
Increased consumption with reduced hashrate — domain failure on hashboard
Fan running at maximum RPM constantly — temperature sensor malfunction
