It has been a while since we have covered new Bminer releases, so we are going t mention that there is new Bmine 16.1.0 that comes with added support for BFC and Cuckatoo32, as well as fixes fidelity issues on Cuckaroo29m and improved stability of ETH mining. As for the reason we haven’t covered this particular miner, it is not because of lack of updates, it is because of a specific issue that is still not fixed under Windows. So half of the reason is because we want to mention how users that are having issues running Bminer on their Windows-based Nvidia GPU mining rigs can resolve it now and not have to wait for a new version that finally fixes this.

If you run Bminer and get an error saying “Failed to initialize the CUDA platform: CudaError: Could not initialize the NVML library” then there is nothing wrong with your mining hardware, the problem is in the Bminer. The reason is that newer Nvidia GPU drivers have moved the nvml.dll library that the miner uses into a new location and Bminer is looking for the NVML dynamic link library in a specific location, so even if you copy the DLL file in the same folder where the miner is it will still not work. If you are using newer Nvidia drivers you will have to copy the “nvml.dll” file from the “\Windows\System32\” folder to “\Program Files\NVIDIA Corporation\NVSMI\” and have in mind that you need to create the NVSMI folder there as it will not exist and then copy the DLL. Running Bminer after copying the library (do not move the file, or other programs might stop working properly, just copy it!) to the specified folder should eliminate the error message and the miner should start normally again.

We remind you that that Bminer is a closed source Nvidia GPU miner available for Linux and Windows in the form of pre-compiled binaries and that there is a 2% development fee for Grin, Beam, Bytom (BTM), Equihash and Zhash coins, 0.65% for Ethash and 1.3% for dual mining Ethash and Blake.

There is one more incentive for anyone willing to switch their CPU/GPU mining hardware from crypto mining to helping the Folding@Home in their fight against COVID-19 coming from the Crypto-Games Team who are giving away 0.5 BTC to join their Folding@Home team. In order to be able to participate in this incentive you need to use the following team number in your Folding@Home client – 247983 in order for your stats to be tracked.

Starting right now and until the end of April or until they run out of rewards, there will be a team competition for most Credits completed within the Folding@home team. The prize pool is 0.50 BTC for this event, all prizes will be dealt via the tipping feature on the Crypto.Games website, so if you do not have an account yet, you would need to sign up for one. You need to post your F@H username and CG username in a dedicated thread on the Bitcointalk forum or in Crypto.Games Discord server in order to be assigned to one of three squads, then for every 100k credits you complete while folding, you will get 0.0001 BTC or an altcoin equivalent.

The maximum reward for one user is at 0.01 BTC, which can be reached with 10 Million credits accumulated in F@H, though continuing after that will still contribute to your group’s total. In addition to the individual rewards, you and your squad will compete against the other groups for the most combined Credits. The first placed squad gets 0.06 BTC, the second gets 0.03 BTC, and the last gets 0.01 BTC. Rewards are distributed evenly for each and every member of the group, assuming they did complete 5 or more Work Units. Furthermore 0.05 BTC will be rewarded with lottery tickets to users that participate, but do not have a lot of computing power.

Apart from donating your computing power for free, or taking part in this incentive, you can also earn CureCoin (CURE) as well as earn Banano (BAN). So there you have multiple options to both help with the coronavirus fight and at the same time also earn some crypto in order to at least cover some part of the electricity costs of your mining hardware… or if you just need some extra incentive.

One of the most interesting features of the brand new Braiins OS+ firmware for Antminer S9 ASIC miners is the auto-tuning functionality that automates per-chip overclocking in order to maximize performance for the available power and temperature conditions in order to increase the performance of your available miners. Since we already had a couple of S9 ASIC miners that used older release on the Braiins OS we did a quick and easy upgrade offer SSH to the latest Braiins OS+ release and decided to do a quick test of the auto-tuning feature. We remind you that the OS+ version is not completely open source and “free” like the normal Braiins OS, but it is the one that features the auto-tuning option. Braiins OS+ has a 2% developer fee built-in as a means to help further development, but thanks to the auto tuning feature you should be able to squeeze some extra performance to cover the fee and still be better than manual or stock settings.

We started our testing by disabling the temperature control and forcing the fans to operate at 100% all the time in order to ensure that the cooling performance will be at maximum level all the time for these air cooled S9 miners. Then we have set the PSU power limit to 1500W and started waiting for the automated script to do its magic in finding what the optimal settings would be for all of the chips in the ASIC miner and what will be the final hashrate we are going to be getting in a while from this stock 14 THS SHA256 ASIC miner. Do note that you are not actually required to specify a power limit of the PSU that the autotuning algorithm can take into account in order to maximize the TH/W produced by the mining device, but that can help to ensure that you will not have problems caused by the miner reaching the limits of the PSU you are using.

The result after leaving the auto-tuning to run a while on the miner showed the following result: 16.5-16.6 THS hashrate within the set power limit of 1500W and operating temperatures of the chips trying to stay below 90 degrees Celsius with the cooling fans operating at 100%. We should also note that even though the firmware may do per-chip optimizations for best results, the web-based interface does not provide you with detailed per-chip information, you still get a somewhat summarized hash chains information. We are not sure how long it may take for the auto-tuning to finish or of it actually finishes or tries to find optimal settings when operating conditions change… it is just not well documented for the moment, but it does seem to be working pretty well based on our first experience using it. Of course depending on a lot of conditions the results you will be getting from the auto-tuning feature may vary from miner to miner, so do not expect to see the same improvement on all of your available S9 miners!
