Profit and payback are estimates from today's coin prices and network difficulty, before pool fees, hosting and taxes. They change every day. Not financial advice.
Rankings use the algorithm's main coin (BTC for SHA-256, LTC + DOGE for Scrypt): small side chains may pay more per hash today but can't absorb much hashrate.

Getting a fan error. How do I find which of the four fans has failed?
AsicProfit SupportAsicProfit · Oct 27, 2026
The fan numbers in the log do not always match the labels on the control board, which confuses many owners. The quickest way is to check the fan speeds in the status page, then unplug fans one at a time and watch which reading changes. Replace with a fan that has the same connector type. Owners running several units keep spare fans on hand, since fans fail far more often than boards.

how noisy is the s19k pro, could it go in a spare bedroom with a sound box
AsicProfit SupportAsicProfit · Oct 22, 2026
It is listed at about 75 dB with four fans, which is too loud for a bedroom. A sound-dampening box helps, but it must not starve the miner of air. One owner's abnormal hashrate and restart problems went away after taking the miner out of its noise box and reseating the power cables. A garage or ventilated outbuilding, with ducting for the hot exhaust, is the usual home setup.

Is a 23 J/TH machine like the S19k Pro still worth buying now?
AsicProfit SupportAsicProfit · Oct 19, 2026
It can be, but only with cheap power. At around 23 J/TH it spends more electricity per terahash than current-generation machines, so rising network difficulty or a lower Bitcoin price squeezes its margin first. Its appeal is a lower purchase price and modest 2.76 kW draw. Put your real electricity price into the calculator on this page and compare it with a newer model before deciding.

Can I run an S19k Pro on 110V/120V household power?
AsicProfit SupportAsicProfit · Oct 1, 2026
No. It is built for 220V-class input and draws about 2,760 W, and an experienced forum helper warned an owner that it will not run normally on 110V. On 230V it pulls about 12A, so give it a dedicated circuit rather than sharing one with other loads, and plug it in directly instead of through a light extension lead. Unstable power is a common cause of restarts and hashrate drops.

Updated firmware and now it says board name doesn't match and won't hash. Can I fix it?
AsicProfit SupportAsicProfit · Sep 17, 2026
That error means the firmware does not match your hashboard revision. Newer S19k Pro batches can need a specific firmware, and flashing third-party or older images can leave the unit unable to start. If the unit is still under warranty, ask Bitmain support for the correct firmware for your serial number first. The SD card recovery image from Bitmain's download page is the next step. Avoid flashing a new, working machine just to try other firmware.

one hashboard only finds 76 of 77 chips after a restart, what should i check?
AsicProfit SupportAsicProfit · Sep 17, 2026
Start simple: power off, reseat and clean the data cable between control board and hashboard, then test each board on its own, since one faulty board can upset readings for the others. Try the stock firmware and a factory reset. If the board still drops a chip, a missing chip in a series chain usually needs a repair shop or a warranty claim. Some third-party firmware will run a board with a weak chip, but it cannot bypass a dead one.
