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.
