The changes in this release (since 5.2c) include the following:
- Added support for -daglim for AMD Fiji, Tonga, and Baffin cards with 4GB VRAM, so you will be able to use them some time beyond epoch 373 (Windows), or 381 (Linux)
- New kernels for 4GB AMD cards with higher hashrate when -daglim is in effect
- Added -daglim and -rxboost support in Linux. The default -daglim value in Linux is 4064 for older drivers (before 19.50), and 4076 for the newer drivers
- Added support for the AMD Linux drivers 20.20, and 20.30
- Added support for the latest AMD Linux drivers 20.40-1147286 (however they seem to have hardware control problems with some cards, so no need to upgrade for now)
The changes of the previous beta (5.2c) since the last version (5.1c) are:
- The kernels are modified to allow bigger DAG limit of 4023 MB under Windows. This allows higher hashrate when the DAG is bigger than the available VRAM.
- The -daglim parameter is now on "auto" (1) by default and it sets the DAG limit to 4023, so you don't need to set -daglim 1 or -daglim 4023 if the default value is working fine.
- AMD cards with more than 4 GB RAM will now work without issues until DAG epoch 450
- Added new -daglim parameter to allow a few more weeks of work for 4 GB AMD Polaris cards. Use -daglim 1 for automatic operation, or specify a concrete value for the maximum DAG size (example: -daglim 4000 will set max DAG size 4000 MB)
- Added -rxboost parameter (also accessible via -vmr) to boost the performance of GDDR5 based AMD cards (Polaris or earlier)
- Added memory straps support for AMD Vega cards. Use the -straps command-line option to activate it (example: -straps 1 will activate the lowest strap level)
- The Nvidia memory timing (straps) option is improved and now is turned off during DAG generation to avoid any possible instability issues
- Many other small improvements and fixes
Here are some additional notes:
- The -daglim option works on Polaris (RX470, RX480, RX570, RX580, RX590), Baffin (RX560, RX550), Tonga, and Fiji cards. It limits the DAG size to
MB to allow mining on 4 GB cards a few weeks after epoch 374 on Windows (or after 381 on Linux). The possible values are the exact DAG limit in MB, or 0 (turn off the DAG limit), or 1 (automatic DAG limit size, usually around 4023 MB under Windows; this is the default option). Note that the hashrate will drop significantly with each epoch after the DAG limit is in effect. If the hashrate drops too much (e.g. from 28 MH/s to just 2-3 MH/s, you need to use lower value, for example -daglim 3990 - (Windows) With PhoenixMiner 5.2d either remove the -daglim option entirely (it is set to auto by default), or set it to -daglim 4023, which should work on all 470/480/570/580/590 cards with "good" drivers (see bellow)
- (Windows) If you cards doesn't work with the default DAG limit of 4023 and require substantial decrease to 4006 or 3990, you need to update to one of the "good" AMD drivers for Windows: from 18.12.1.1 to 19.7.5 (inclusive), and from 19.12.2 to 20.11.1 (inclusive)
- (Linux) With PhoenixMiner 5.2d either remove the -daglim option entirely (it is set to auto by default), or set it to -daglim 4064 on older drivers (before 19.50), or -daglim 4076 on newer drivers.
- (Linux) When the -daglim option is in effect (i.e. if you are mining ETH or ETC with 4GB cards), the miner will restart on each new DAG epoch, and will force serial (one-by-one) generation of the DAG buffers. To allow more stable operation under these conditions, it is best to use -rmode 0 and to use a script to restart the miner when it exits. Two such scripts are provided with the miner: start_amd_4g_old_drv.sh for older drivers (before 19.50, note that when using -rmode 0, the -daglim for these older drivers can be increased to 4068), and start_amd_4g_new_drv.sh for newer drivers. Make sure to change the pools and the wallet in these scripts with your own before using them for mining.
- It is also important to use auto-tune (do not specify -gt values in the command line) because the optimal -gt value may change with each new epoch, and will definitely be different than before.
- Using -rxboost, -vmr, or -straps on AMD cards requires running as administrator (or as root under Linux), so you need to run PhoenixMiner as administrator for the VRAM timing options to work. Note that the -mt option will still work without running as administrator.
- The -rxboost option is only supported on GDDR5 cards (RX4xx/RX5xx or older).
- The VRAM timing options can be quite different between the GPUs, even when the GPUs are the same model. Therefore, you can (and probably should) specify the VRAM timing options separately for each GPU.
