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.

It did not take long and now the latest GMiner 2.04 GPU miner had added support for the new KAWPOW mining algorithm that RavenCoin (RVN) might/could/should/would be forking to sometime in April. The KAWPOW algorithm is a derivative of ProgPOW with parameters specific for RavenCoin, so another miner with ProgPoW support will not work unless specific RVN support is added like in the case of GMiner that already had ProgPoW support, but needed an update for KAWPOW support. Do note that support for KAWPOW is currently only available for Nvidia GPUs and that goes for ProgPoW as well. You can already test KAWPOW support on the RavenCoin test network to get ready your miner, there miner RVNt testnet tokens do not have any value though.

Besides the new algorithm being added, the latest version of GMiner addresses an issue we have noted regarding high CPU usage in Qitmeer (PMEER) support. There is a new “--trim” parameter being introduced to control additional trim round count for Cuckoo24 (Qitmeer) algorithm that should help reduce CPU load, so you can give it a try and see if it helps if you have any GPU mining rigs with lower-end CPUs that have high CPU load issue.

The GMiner miner software was originally only an Nvidia GPU miner, although some algorithms are already supported on AMD GPUs as well. Do note that GMiner is a closed source miner for Nvidia and AMD GPUs with binaries available for both Windows and Linux, there is a 2% developer fee built-in the software.

The latest GMiner 2.03 GPU miner adds support for the Qitmeer (PMEER) mining, however do not be in a hurry to try mining using the Cuckoo24 algorithm that has been just added. Have in mind that the Qitmeer (PMEER) mining support comes with a 5% developer fee and is apparently CPU intensive, so you might have trouble using the latest GMiner with Qitmeer (PMEER) mining on mining rigs with most typical dual-core lower performance processors. Frankly we are a bit disappointed that the official release notes do not mention the higher developer fee for the new algorithm, nor that it is apparently heavier in terms of CPU requirements.
