IMPORTANT! Nvidia drivers for Windows 10 since ver. 460.79 (and newer) cause crash when PhoenixMiner starts. If you want to use these drivers, you need to upgrade to PhoenixMiner 5.4c or later version.

IMPORTANT! Ethereum Classic (ETC) network switched to a modified version of ethash, called ETCHash. If you are mining ETC you must upgrade to PhoenixMiner 5.3b or later, otherwise you will get only rejected shares when mining ETC.

IMPORTANT! All owners of AMD cards with 6 GB or 8 GB RAM must either keep drivers 20.4.x or lower (do not upgrade to 20.5.1 or later), or upgrade to PhoenixMiner 5.2e or later version to continue mining after DAG epoch 384 (ETH will pass it before the end of 2020).

IMPORTANT! All owners of AMD cards with 4 GB RAM must upgrade to PhoenixMiner 5.2e or later version to continue mining after DAG epoch 373. Additionally, here are some important tips for longest possible usage of 4 GB AMD cards with PhoenixMiner 5.2e and later:


Changes in version 5.5c (since 5.4c):

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 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 support for AMD Linux drivers 20.45-1164792 and 20.45-1188099. Use this drivers only if you have RX6800 or RX6900 GPU. WARNING: Vega and Navi GPUs won't 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
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 provided by the user 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 is fast (arguably the fastest) Ethash (ETH, ETC, Muiscoin, EXP, UBQ, etc.) miner that supports
both AMD and Nvidia cards (including in mixed mining rigs). It runs under Windows x64 and Linux x64
and has a developer fee of 0.65% (the lowest in the industry). This means that every 90
minutes the miner will mine for us, its developers, for 35 seconds.

PhoenixMiner also supports ETCHash for mining ETC, Ubqhash for mining UBQ, ProgPOW for mining BCI, and dual mining
Ethash/Ubqhash with Blake2s.

The speed is generally faster than Claymore's Ethereum miner in eth only mode
(we have measured about 0.4-1.3% speed improvement but your results may be slightly lower or
higher depending on the GPUs). To achieve highest possible speed on AMD cards it may be needed
to manually adjust the GPU tune factor (a number from 8 to about 400, which can be changed
interactively with the + and - keys while the miner is running).

If you have used Claymore's Dual Ethereum miner, you can switch to PhoenixMiner with
minimal hassle as we support most of Claymore's command-line options and confirguration
files.

1. Quick start

You can download PhoenixMiner 5.5c from here:

Download: https://www.sendspace.com/folder/ugy44z


2. Features, requirements, and limitations

* Supports AMD RX5700, Radeon VII, Vega, 580/570/480/470, 460/560, Fury, 390/290 and older AMD GPUs with enough VRAM
* Supports Nvidia 30x0, 20x0, 16x0, 10x0 and 9x0 series as well as older cards with enough VRAM
* Highly optimized OpenCL and CUDA cores for maximum ethash mining speed
* Optional "green" kernels for RX580/570/560/480/470/460 to lower the power consumption by 2-3% with small, or no drop in hashrate
* Lowest developer fee of 0.65% (35 seconds defvee mining per each 90 minutes)
* Dual mining ethash/Blake2s with lowest devfee of 0.9% (35 seconds defvee mining per each 65 minutes)
* Advanced statistics: actual difficulty of each share, effective hashrate at the pool, and optional showing of estimated income in USD
* DAG file generation in the GPU for faster start-up and DAG epoch switches
* Supports all ethash mining pools and stratum protocols
* Supports secure pool connections (e.g. ssl://eu1.ethermine.org:5555) to prevent IP hijacking attacks
* Detailed statistics, including the individual cards hashrate, shares, temperature, fan speed, clocks, voltages, etc.
* Unlimited number of fail-over pools in epools.txt configuration file (or two on the command line)
* Automatic GPU tuning for the AMD GPUs to achieve maximum performance with your rig
* Supports devfee on alternative ethash currencies like ETC, EXP, Music, UBQ, Pirl, Ellaism, Metaverse ETP, PGC, Akroma, WhaleCoin, Victorium, Nekonium, Mix, EtherGem, Aura, HBC, Genom, EtherZero, Callisto, DubaiCoin, MOAC, Ether-1, and EtherCC. This allows you to use older cards with small VRAM or low hashate on current DAG epochs (e.g. GTX970).
* Full compatibility with the industry standard Claymore's Dual Ethereum miner, including most of command-line options, configuration files, and remote monitoring and management.
* Supports the new Ubqhash algorithm for the UBQ coin. Please note that you must add -coin ubq to your command line (or COIN: ubq to your epools.txt file) in order to mine UBQ
* Supports the ProgPOW algorithm for the Bitcoin Interest (BCI) coin mining. Please note that you must add -coin bci to your command line (or COIN: bci to your epools.txt file) in order to mine BCI
* Supports the ProgPOW algorithm for mining BCI.
* More features coming soon!

PhoenixMiner requires Windows x64 (Windows 7, Windows 10, etc.), or Linux x64 (tested on Ubuntu LTS
and Debian stable).
