Which coins can the Z15 Pro actually mine, only Zcash?
AsicProfit Support AsicProfit · Oct 19, 2026
The Z15 Pro runs the Equihash 200,9 algorithm, which means mainly Zcash (ZEC). Bitmain's support spec also lists Horizen (ZEN). Coins with other Equihash variants or other algorithms will not run on it. Check that your pool supports Equihash ASICs. The calculator above shows current earnings for the coins it can mine at your power price.

Z15 Pro vs the 860 KSol version, is there any real difference?
AsicProfit Support AsicProfit · Oct 10, 2026
Bitmain's official spec is 840 KSol/s at 2780 W, or about 3.31 J/KSol, with 3 hashboards and 18 chips in total. Listings at 860 KSol/s are a higher bin or tune of the same machine, so expect slightly higher power draw. Compare the rated watts on each listing as well as the hashrate, and use the calculator above to see whether the extra hashrate is worth it at your power price.

My Z15 keeps rebooting after a minute or two, what should I check?
AsicProfit Support AsicProfit · Oct 8, 2026
Owners report Z15 units that power up, spin the fans hard, then restart in a loop. Things to try: test with a known-good power supply, check every fan reports a speed, and run the miner with one hashboard disconnected at a time to find a faulty board. Bitmain says a fan reading zero or an unusually high speed means that fan needs replacing. If replacing the fan does not fix it, the control board may be at fault.

How noisy and hot does the Z15 Pro run, and what's the warranty?
AsicProfit Support AsicProfit · Sep 29, 2026
Bitmain rates it at 75 dBA with fans at full speed, so it is not suited to living space. Keep intake air between 0 and 40 C. Bitmain's 19-series and Z15 guidance puts the PCB limit at about 80 C, and the miner protects itself by shutting down near that. The shop lists a 180-day warranty from shipping for the original buyer.

Does the Z15 Pro need two power cables?
AsicProfit Support AsicProfit · Sep 27, 2026
Yes. Bitmain's spec shows two AC inputs at 10 A per wire, with an input range of 200 to 240 V AC at 50 to 60 Hz. Rated draw is 2780 W at 25 C intake air. Plan for 220 to 240 V circuits that can carry the load continuously, and do not run it on 110 to 120 V.

Can a Z15 Pro be put in immersion or run with the fans removed?
AsicProfit Support AsicProfit · Sep 25, 2026
Not with stock settings. Owners who tried immersion found the stock firmware gives little fan control and halts when it cannot read fan speeds, so people used aftermarket firmware or fan-signal tricks. Bitmain lists the Z15 Pro as an air-cooled miner for 0 to 40 C, and modifying it can void the warranty. If you want liquid cooling, a miner built for it is the safer route.
