What operators noticed after tuning

These are practical signals from real machines: what the operator changed, what the miner did next and which detail must be checked before anyone copies the setup.

Antminer S19 95T

Solar S19 profile at 1,100 W and 15.9 J/TH

A solar operator reported an S19 95T at 1,100 W and 15.9 J/TH, while praising the interface, autotuner and per-chip tuning.

Source-reported1,100 W · 15.9 J/TH
Derived from reported valuesimplied ≈69.2 TH/s

Operator takeaway: copy no preset blindly; log model, board, power ceiling and cooling, then test one canary.

Antminer, model not stated

Granular power control and a modern interface

An operator highlighted fine power control and the interface, and reported continued operation during a fan-speed reporting fault while temperature remained the key protection signal.

Source-reportedPower control · interface · sensor context

Operator takeaway: inspect the underlying sensor and error state before changing a protection rule.

Loki-modded Antminer S19j Pro

Two low-power points on a Loki-modded S19j Pro

The operator reported about 45 TH/s at 1,200 W and 28 TH/s at 900 W on a Loki-modded, two-board S19j Pro using a 120 V APW3 supply.

Antminer S19j Pro 104T · oil-immersion fleet

Immersion fleet: two S19j Pro 104T operating points

An operator working with an oil-immersion S19j Pro 104T fleet reported about 128 TH/s at a 4,300 W VNISH setting and around 124 TH/s at roughly 3,800 W, noting the efficiency trade-off.

Antminer S19 family

Undervolting used to contain heat

In an S19 undervolting discussion, an operator described using VNISH for a strong underclock specifically to limit heat.

Source-reportedThermal objective · underclock

Operator takeaway: define the thermal limit first, then tune below it and keep a rollback path ready.

Source policy

Turn every story into a canary

A useful field report is not a preset. Identify the exact machine and board, set a power ceiling, prepare recovery, then validate temperatures, errors and pool-accepted work on one miner before scaling.

How this collection is built

How this collection is built

We include product-specific positive field reports with a dated public original and a direct source link. Distributor, reseller, hosting-provider, affiliate and sales-led contributions are excluded. Results are paraphrased and remain attributable to their authors.

Hardware condition, board, power supply, cooling, ambient temperature, pool measurement and observation window can change the result. Treat every number as a lead for a controlled canary, not a promise.

The five gold stars are a visual collection marker, not a numeric rating assigned by the author.
