PhoenixMiner 5.1c

[Joseph12]

All owners of AMD cards with 4 GB RAM must upgrade to PhoenixMiner 5.0e or later version to continue mining after DAG epoch 350 (both ETH and ETC has already passed DAG epoch 350). Additionally, here are some important tips for longest possible usage of 4 GB AMD cards with PhoenixMiner 5.0e and later:

Changes in version 5.1c (since 5.0e):

• Added support for VRAM timing adjustments for Nvidia cards of 10x0 series (see the new command-line parameters -straps, -vmt1, -vmt2, -vmt3, and -vmr for more information)
• Added new parameter -nvmem to force using straps even on unsupported Nvidia GPUs (use -nvmem 1 for GDDR5 cards, or -nvmem 2 for GDDR5X cards)
• Added -ttli option to automatically decrease the mining speed to avoid overheating the GPUs over the target temperature (useful when -tmax option is not supported by the drivers)
• Added support for latest AMD drivers 20.8.1 under Windows and 20.20-1089974 under Linux
• Fixed long-standing problems with -gpow option, which now works properly
• Removed some dead ethash-based altcoins and updated the support for the rest of them
• Many 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 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.
