It seems that just like with the newer Antminer Z9 Mini the new faster Antminer Z9 Equihash ASIC miners from Bitmain are arriving with locked overclock functionality in the firmware. We already know that these ASIC miners are overclocking pretty well and you can easily get a nice performance boost over the stock hashrate the devices come with, so why is Bitmain limiting you… it is pretty clear, they want you to buy more units. Fortunately there are alternatives that allow you to overclock your Antminer Z9 miners and get a nice extra performance boost. Initially there was only a modified firmware released by user efudd on Bitcointalk that was sold to interested people, but now there is also a free version of a modified firmware available with unlocked frequencies by smartass111. Of course you are more than welcome to make a donation to the author of the modified firmware in order to support and motivate him.

The new faster in terms of hashrate Bitmain Antminer Z9 ASIC miners do seem to be more limited in terms of operating voltage, so you will most likely will not be able to overclock them as much as a Z9 Mini, but still going from the default operating frequency of 500 MHz to 625 or 650 MHz should be possible on pretty much all miners. If you are lucky you might be able to even squeeze some more extra as well, just make sure you keep the chips cool enough when you start to overclock and also to have a powerful enough power supply that can handle the extra load that it will get after the overclock. Getting an extra performance boost of 20% or maybe even a bit more for free is something that you should definitely take advantage of if you have some Antminer Z9’s.

Bitmain has finally announced their next generation of ASIC chips that are based on 7nm Finfet technology called BM1391 for the SHA256 algorithm, these chips will power the next generation of Bitcoin ASIC miners coming from the company. The new BM1391 chips integrate more than a billion transistors and are optimized for maximum efficiency according to the company and can achieve a ratio of energy consumption to the mining capacity that is as low as 42 J/TH. Bitmain was dominating the Bitcoin mining market with their Antminer S9 in terms of hashrate and units shipped, but they started losing in terms of performance and efficiency lately due to the fact that the competition was adopting new production technologies and making further optimizations to get higher hashrates. We’ll see if Bitmain will be able to get back in the game with their next generation ASIC miners using the new chips…

WhatsMiner M10 is a Chinese Bitcoin ASIC miner that is apparently starting to ship just now that promises performance comparable to other top SHA256 ASICs available on the market at the moment. At 33 THS with 2145 Watts of power usage it is surprisingly efficient for 16nm chips available at a price of $2000-1800 USD including a power supply. What is more interesting though is that MicroBT, the manufacturer of the WhatsMiner, has just announced their next product called WhatsMiner M10S that will supposedly be able to deliver up to 55 THS with about 3500W of power usage at 65W/THASH or 44 THS with about 2600W at 60W/THASH power usage.

Whatsminer M10 Specifications:
– Chips: 315 * 16nm ASIC
– Hashrate: 33TH/s (+/- 5%) (depends on cooling)
– Power Consumption: 65 W/THS, 2145 W per miner (+/- 10% )
– Power Supply Unit: WhatsPower P5, 2500w, 93% efficiency 220V
– Operating Temperature: -5C ~ 40C
– Dimension: 34cm x 20cm x 17cm
– Weight: 8.55 kg

The only problem with ASIC miners going forward with higher performance is the increased power usage and that is causing trouble for people that are running smaller mining farms, let alone small home miners that do not have the infrastructure available that is capable of handling this high power usage per device. Anyway, with the current market situation it is arguable what is wiser to do – invest in Bitcoin mining equipment or buy directly BTC and hold, that is if you are investing fiat, not crypto.
