Z-Enemy 2.6.3 Beta Nvidia GPU Miner for KAWPOW Mining of Ravencoin (RVN)

21, Feb 2021

Last year Ravencoin (RVN) has successfully hardforked and switched to KAWPOW as a mining algorithm from the previously used X16Rv2 algo. The latest Z-Enemy 2.6.3 Beta version that was recently made available is an important update for everyone that has Nvidia GeForce RTX 30 Series of GPUs and uses them for crypto mining. This is a TEST BUILD of the software that adds support for Nvidia RTX 30×0 video cards with CUDA 11.1 and drivers ver. 456.81 or later. It is intended for RTX 3060 Ti, RTX 3070, RTX 3080 and RTX 3090 GPUs, if you have an older Nvidia GPU you should use the latest stable release Z-Enemy 2.6.2 instead. This official and not beta version works on CUDA 9.x and CUDA 10.x and it is recommended to make sure you’ve updated your NVIDIA video drivers to at least version 398 or a newer one.

The KAWPOW algorithm used by Ravencoin is a derivative of ProgPOW with parameters specific for RVN, so performance wise you can expect similar hashrate to what ProgPOW delivers. ProgPOW or Programmatic Proof-of-Work was designed in a way that it utilizes graphics processors to their maximum in order to provide an equal level performance without favoring a specific GPU manufacturer or being able to actually provide much faster hashrate if implemented on ASICs. The ProgPOW algorithm was made as a kind of evolution of the Ethash algorithm used by Ethereum and at some point ProgPOW was even considered as a replacement algorithm for Ethash for Ethereum. The idea here is that a cheaper GPU with better video memory will not perform better like in some cases for Ethereum, but instead the performance you get will be based on the overall GPU performance level – both of the GPU and the VRAM.

KAWPOW was based off ProgPOW as a means to drive away any FPGA and/or ASIC mining hardware that was starting to become available on the Ravencoin’s network and the fork was successful in doing so, but it took a bit of time for things to start moving again for RVN. The last few days we are finally seeing that things are moving with Ravencoin price seriously on the move and thus the interest in mining Ravencoin is peaking once again. Mining RVN has also become quite profitable due to the increase in the price of the coin, so people are considering switching some of their GPU mining power to mine RVN as profitability gets closer to that of Ethereum mining.

The KAWPOW mining algorithm uses both GPU and memory, so overclocking both can help you maximize performance, though you should start without overclock and see what your mining hardware can handle. This can however increase the power usage and operating temperatures for achieving optimal performance when mining RVN on the same hardware as opposed to mining ETH with optimal performance! Do note that KAWPOW and PROGPOW use DAGs like Ethash and currently the DAG size of Ravencoin (RVN) is at almost 3GB, so GPUs with 4GB as a minimum for mining will be required. Just as a reference, a single Nvidia GeForce RTX 3090 with settings optimized for 120 MH/s Ethereum mining can do almost 50 MH/s hashrate for KOWPOW mining. Also be advised that the GDDR6X memory temperatures on RTX 3080 and RTX 3090 while mining RVN are much lower compared to when mining ETH, so this may be an advantage especially for people that have trouble with the memory chips running too hot while mining Ethereum.

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!

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%.
