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%.

Team Red Miner 0.7.4 Addressing 4GB VRAM GPUs Support for Ethash

5, Jun 2020

Team Red Miner is a performance optimized cryptocurrency miner for AMD GPUs with support from DAX Aktien kaufen for a number of algorithms with the latest version 0.7.4 focusing on extending Ethash support for 4GB AMD GPUs for as much as possible number of upcoming epochs. Previous version 0.7.3 stopped working at Epoch 351 which Ethereum Classic (ETC) has now crossed, so anyone running 4GB AMD GPUs on ETC or Nicehash should update to this updated version as soon as possible. With Team Red Miner 0.7.4 Ethash support on 4GB GPUs should be available up to Epoch 380-383 wit ETC reaching them about a month ahead of ETH later this year. An alternative option for 4GB AMD GPUs mining Ethash is PhoenixMiner 5.0b that has also addressed the same issue recently. Apart from addressing issues with Ethash support the new version also brings some extra improvement in KAWPOW performance with results varying depending on the kind of AMD GPU you have available as well as some other general improvements and fixes that you can read about below. Team Red Miner is already the best option for KAWPOW mining on AMD GPUs in our opinion performance wise, but extra hashrate boost is always more than welcome.

Changes in Team Red Miner 0.7.4:
– Increased Ethash support on 4GB GPUs up to epoch 380-383
– Implemented split Ethash DAG buffers for 8GB GPUs to support DAGs over 4GB
– Kawpow optimizations (Navi +2.25%, Vega +1.25%, Polaris +0.25%)
– Added Gpu enable/disable API support.
– Windows TDR detection/handling/warning.
– Monitor detection on Windows/Linux with intensity adjustment.
– Fix for Ethash pool hashrate reporting stopping after network outage.

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 all algos except Ethash and KAWPOW, for KAWPOW it is 2% and for Ethash on Polaris GPUs the dev fee is 0.75% and on all other GPUs is 1%.

Ravencoin Classic (RVC) is a Fork Off the Ravencoin (RVN) Blockchain

25, May 2020

It seems that there is a Ravencoin Classic (RVC) fork off the Ravencoin (RVN) blockchain that has happened along the last RVN hardfork when the new KAWPOW algorithm has been adopted by Ravencoin. The thing that differentiates RVC from RVN is the fact that the Ravencoin Classic retains the original X16R mining algorithm that has been introduced with the launch of RVN. The idea to fork from X16R to X16Rv2 and then to the KOWPOW algorithm for Ravencoin is to keep RVN GPU mining friendly and to drive away secret FPGA/ASIC miners as such apparently exist for X16R and X16v2 already. Yet the Ravencoin Classic (RVC) fork that retains the original X16R algorithm and is being described by F2pool (the largest pool to support RVC mining at the moment) with things such as “RVC can be efficiently mined with GPU cards” and “RVC cannot be efficiently mined with CPU or ASIC mining machines”. Surprisingly or not the mining profitability with GPUs of RVC with X16R is currently lower for the same hardware RVN with KAWPOW. If you want to learn more about blockchain technology, check out this Youtube Channel.

Now, regardless if you support the Ravencoin Classic (RVC) or not, as with other forks if you had Ravencoin (RVN) in a local wallet, then you will be able to claim your RVC coins at 1:1 ratio to do whatever you want with them. You just need to copy the wallet data file to a new installation of the RVC wallet, make sure you use the datadir command line parameter to use a custom folder for the Ravencoin Classic blockchain data as otherwise it will try to overwrite the RVN data you have available. The RVC wallet should have replay protection already, though it is always wise to first move your RVN coins to a new address before doing anything with RVC, just to be on the safe side! Ravencoin Classic (RVC) is currently being traded only on the Longbit crypt exchange which is an Asian one (switch to English language in the upper right corer of the screen), though it accepts international registrations. It however requires you to go through an identity verification process before you can deposit and trade coins, so have in mind that you need to pass that as well.
