Another update for the NebuTech BTMiner Nvidia GPU miner to version 10.0 for mining Bytom (BTM) that brings another significant performance boost by increasing the hashrate provided by the miner with about 30% or even more compared to the previous version 9.0, depending on what kind of Nvidia GPUs you have in your mining rig of course and the settings they are running at. Anyway, this is a really big performance boost to the miner, so if you are mining Bytom (BTM) with your Nvidia GPU mining rigs you must definitely update to the latest version to take advantage of the increased hashrate. We remind you that the NebuTech BTMiner is a closed source Bytom (BTM) GPU miner for Nvidia CUDA that is available for both Windows and Linux operating systems and it has a 3% developer fee built-in.

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…
