Bitmain has Released a Firmware to Activate “Overt AsicBoost” for Antminer S9 ASICs

22, Oct 2018

Really interesting news for everyone that owns Antminer S9 ASIC miners and other Bitmain BM1387-based models like the Antminer R4, S9i, S9j, T9 and T9+. Bitmain has officially released a firmware to activate the so called “Overt AsicBoost” for Antminer S9 Bitcoin ASIC miners and will have the firmware for Antminer R4, S9i, S9j, T9 and T9+ within a week as well. This comes just a few days after the announcement that Braiins OS might actually bring users support for Overt AsicBoost. According to Braiins the activation of the “Overt AsicBoost” functionality on S9 can bring down the power consumption by about 13% which is more than welcome at the current market situation for any miner using Antminer S9 Bitcoin ASICs. Bitmain however does not officially reveal how the new firmware with “Overt AsicBoost” affects the operating parameters of the S9, though the upgrade should reduce the power consumption for sure. If you upgrade your Antminer S9 miners to the new firmware please feel free to share your feedback in the comments below.

New NebuTech BTMiner 10.0 for Bytom (BTM) With Significant Performance Boost

3, Oct 2018

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.

Firmware With Unlocked Overclock for Bitmain Antminer Z9 Equihash ASIC Miners

2, Oct 2018

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.
