Antminer S19 family
In an S19 undervolting discussion, an operator described using VNISH for a strong underclock specifically to limit heat.
A dated original preserves when this capability was already being reported.
Antminer S19j Pro 104T · oil-immersion fleet
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.
A dated original preserves when this capability was already being reported.
Antminer T21
A forum operator reported a first T21 running VNISH at a 175 TH/s target in a single-phase conversion using backup S19j Pro power supplies.
This adds a traceable hardware-generation marker to the product history.
Loki-modded Antminer 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.
This adds a traceable hardware-generation marker to the product history.
Antminer, model not stated
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.
The newer report shows the same control theme continuing in later operator use.
Antminer S19 95T
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.
The captured post does not state whether the figures came from wall measurement, the controller, or an average over a stated time window. Treat 15.9 J/TH as an unverified source report.
The newer report shows the same control theme continuing in later operator use.
Source policy
Across several hardware generations, operators repeatedly describe the same product themes: a wider power envelope, granular tuning, thermal control and a more usable control surface. The timeline records those signals without turning selected posts into an aggregate score.

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. The platform, date and permalink remain visible. Account handles are withheld unless the author gives explicit permission.
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.
