New GMiner 2.43 With Focus on Ethash Mining Improvements and Stability

27, Jan 2021

The latest GMiner 2.43 Nvidia and AMD GPU miner continues improving on Ethash support including compatibility with pools as well as new kernels for Nvidia. The latest update adds two new kernels for Ethash, so that now the miner support 5 kernels for Nvidia GPUs in order to ensure optimal performance depending on your GPU. Gminer automatically selects the optimal kernel by default, but you can also select specific kernel by the --oc command line parameter. The latest version also brings improved handling of device freezing as well as improved auto-tuning.

GMiner 2.43 Nvidia and AMD GPU miner changelog:
– improved compatibility with Ethash pools (shardpool.io)
– improved handling of device freezing
– improved auto-tuning
– added two kernels for Ethash, miner support 5 kernels for Nvidia GPUs, miner automatically select optimal kernel, also you can select specific kernel by --oc parameter

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 standard 2% developer fee built-in the software, though Ethash fee is 0.65% and KAWPOW fee is 1%, but there are some fees that go higher than 2% as well!

More Epochs Мod v1.4 for Claymore Ethereum (ETH) Miner v15

25, Jan 2021

Up until not long ago Ethereum (ETH) and in general most of Ethash AMD and Nvidia GPU mining was mostly done with Claymore’s Dual Ethereum AMD+NVIDIA GPU Miner v15.0, but unfortunately the miner stopped working as it had support up to DAG Epoch 384 for Ethereum. Furthermore, Claymore, the developer of the software has apparently disappeared or at least has stopped updating his software, so miners had to go for alternatives. Currently the most popular miner that has succeeded Claymore’s miner is PhoenixMiner, but Claymore’s miner is not entirely dead yet. Enter the user Justaminer on Bitcointalk, who has apparently modified Claymore’s miner without having access to the source code in order to make it work once more.

Just_a_miner’s modification called More Epochs mod for Claymore ETH Miner v15 brings support for DAG epochs 385 and later to the miner, so that you can continue using it. The only difference is that the 1% development fee will not go to Claymore anymore (it cannot because his miner is not working anymore), but to Just_a_miner who has revived the Claymore miner back from the dead and will hopefully keep it working on the long run. His modification brings support of DAG epochs up to 500, fixes bugs of the original miner such as restoring access to nvml.dll on Windows 10, adds support of new Nvidia drivers 460.89+. So, it is not just a modification to enable support for newer DAG epochs, but other issues of the original miner also have been addressed. Currently this mod supports only the Windows version of the miner and is targeted at Nvidia GPUs, however there is also test support of several AMD Radeon GPUs: RX 470, RX 480, RX 580, Vega and Navi. The latest version of the Claymore mod from Justaminer is 1.4, so make sure you download and that one and not an earlier version.

TeamRedMiner 0.8.0 With Improved Support for the Ethash Algorithm

24, Jan 2021

Team Red Miner is a performance optimized cryptocurrency miner for AMD GPUs with support for a number of algorithms with the latest major version 0.8.0 bringing rewritten Ethash kernels and new mining modes for all GPU types. This means you should get better hashrate at a slightly lower power consumption on most recent AMD GPUs. In general, TeamRedMiner (TRM) behaves similarly to other AMD Ethash miners, the key difference is the additional mining modes (B/C-modes) that use additional VRAM on the GPUs for further beneficial effects.

Key highlights of the TRM 0.8.8 release:
– Polaris: Efficiency and slight hashrate increase. B-mode reintroduced for added hash. B-mode must be enabled with --eth_aggr_mode or --eth_config=Bxxx.
– Vega 56/64: greatly improved base kernel for efficiency. New B-mode that can shave off additional 1-2W on top of the A-mode kernel. B-mode must be enabled manually with --eth_config (--eth_aggr_mode does not apply). Tuning numbers have changed – do NOT keep your old static –eth_config values.
– Radeon VII: huge boost with its new C-mode but requires a special Linux setup. Can now do 100 MH/s on most air cooled VIIs. See tuning guide.
– 5700/5700XT: can shave off as much as 8-9W(!) of power using the new B-mode and dropping core clk+voltage. B-mode now the default mining mode. Unless you retune your core clk+voltage you will see a tiny power draw increase instead and not benefit from the upgrade, so read the migration guide.
– 5600XT: new B-mode has a much smaller effect. A-mode remains the default mining mode. See new tuning guide for more details.
– The DAG cache is NOT compatible with the new B/C-modes. ETH+ZIL switchers have to choose between caching the epoch 0 dag and using the new mining modes.
– Ethash 4GB kernels NOT rewritten in this release, performance remains the same as in 0.7.x.

The miner is available for both Windows and Linux operating systems, a closed source software with 2.5% to 3% development fee built-in for most algorithms except Ethash and KAWPOW, for KAWPOW it is 2% and for Ethash on Polaris GPUs the dev fee is 0.75% and for all other AMD GPUs is 1.0%.
