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

PhoenixMiner 5.5b With Improved Performance and New Features

22, Jan 2021

The latest beta version of PhoenixMiner 5.5b might be of interest for those of you that are trying to mine with the newest AMD Radeon RX6800 and Radeon RX6900 GPUs as it adds support with native kernels giving you better performance. AMD’s Polaris, Vega and Navi GPUs should also perform a bit better and use a bit less power for Ethereum mining thanks to optimized kernels – just make sure to user drivers 20.5.1 or later under Windows 10, or 20.10.x or later under Linux. Nvidia’s dedicated mining GPUs P106, P104, etc. also get better support for tweaking under Windows

PhoenixMiner 5.5b Full Changelog:
– Added native kernels for AMD RX6800 and RX6900 GPUs. These are faster than the generic kernels and produce a lot less stale shares.
– Updated kernels for AMD Polaris, Vega and Navi GPUs that are slightly faster and use less power than before when mining ETH. To use these updated kernels, you need to use drivers 20.5.1 or later under Win10, or 20.10.x or later under Linux!
– The Nvidia mining cards (P106, P104, etc.) can now use straps and hardware control options (power limit, memory overclock, max temperature, etc.) under Windows.
– Added support for AMD Linux drivers 20.45-1164792 and 20.45-1188099. Use this driver only if you have RX6800 or RX6900 GPU. WARNING: Vega and Navi GPUs wont’ work with these drivers!
– Automatically set -ttli instead of -tmax when the later is not supported by the driver. This will throttle down the GPUs when they reach the specified temperature to avoid overheating.

Do note that the AMD’s Radeon drivers for Windows do not support compute mode for Hawaii cards (Radeon 290/390 series), so the hashrate will be quite low (14-15 MH/s with the current ETH DAG epoch). This problem is easily fixed mining ETH under Linux, where you can get the full 29-30 MH/s speed out of the Hawaii cards.

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%.
