Bitmain Teasing With the Upcoming AntMiner E9 Ethereum Miner

25, Apr 2021

Bitmain is teasing with the apparently soon to be launched new Ethash miner called Antminer E9 that is supposed to be offering 3 GH/s mining hashrate with 2556 Watts of power usage and 0.85 J/M power efficiency. This is what they claim to be the equivalent of 32 RTX 3080 graphics cards and it roughly is in terms of performance. So, the Antminer E9 is going to be offering similar performance to 32x Nvidia GeForce RTX 3080 GPU mining rig mining Ethereum with GPUs optimized for close to 100 MH/s hashrate, but with power usage at just about 1/3 of what the GPUs will need. Hopefully with a price that is much less compared to how much these video cards will cost you currently, though there is still no exact launch date or pricing information released…

Bitmain however is not the first to upgrade their already outdated dedicated Ethash miner, namely the Bitmain Antminer E3 that has been around for ages. There are other competitors on the dedicated ETH miners market, namely Innosilicon and Linzhi. Innosilicon’s new ETH miner – the Innosilicon A11 is supposedly going to deliver 2100 MH/s Ethash hashrate with just 2300W of power usage, while the newcomer Linzhi and their Linzhi Phoenix ETH miner is supposedly capable of 2600 MHS hashrate for Ethash with a power usage of 3000-3500W. So, Bitmain is going to be doing better in terms of performance and with lower hashrate if the specs of their AntMiner E9 ETH miner end up to be right on the spot. It is very likely however that the price will also be reflecting the better hashrate and lower power usage as well, so it could be more expensive than the slower alternatives.

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%.

PhoenixMiner 5.5c RC With Improvements, New Features and Fixes

24, Jan 2021

There is a new Release Candidate (RC) version of PhoenixMiner 5.5c available that brings some new features, improvements and fixes over the things introduced already in the last beta version PhoenixMiner 5.5b. Do note that if using the miner on AMD GPUs, although it comes with support for the latest AMD Windows driver 21.1.1 it is still not recommended to use them as there seem to still be some stability issues. If you already are using the previous 5.5b beta version you might want to give this new release candidate a go, otherwise you might want to stick with the previous stable 5.4c release for a bit more.

PhoenixMiner 5.5c RC Full Changelog:
– Added support for the latest AMD Windows driver 21.1.1 (still, we don’t recommend using the 21.1.1 driver yet – we had some instability issues with it even when just idling on the desktop!)
– Added new -mcdag parameter to reset the memory overclock on Nvidia cards during DAG generation. This may allow you to set higher memory overclock on your Nvidia cards without risking corrupt DAG buffer, which can lead to excessive number of incorrect shares. Use -mcdag 1 (by default the value is 0, which means turned off) to use this new feature.
– Under Linux -mcdag 1 will execute a shell script named daggen.sh (if present in the current directory) for each Nvidia GPU, passing the GPU index as the first argument, and PCIE bus ID as second argument. The miner will then wait for about 7 seconds before starting DAG generation to allow the script enough time to reset the memory overclock.
– The -tt parameter is now strictly for controlling the fan behavior. E.g. -tt 60 sets auto-fan speed with target temperature 60C; -tt -70 sets fixed fan speed 70%; and -tt 0 turns off the fan control. All these can be specified per GPU.
– There is a new -hwm parameter that allows controlling the frequency of the hardware monitoring, which was also done by -tt in the previous versions of PhoenixMiner
– Other small improvements and fixes
