Support legend:

• Y = Supported
• N = Not supported
• L = Limited support: algos are supported on windows and linux with amdgpu-pro drivers, not supported on ROCm drivers.

The miner reports GPU hash rates every 30 seconds. These are the full GPU hash rates before dev fee deduction (your pool hashrate will be slightly lower).

The miner includes a read-only api based on the sgminer-5.5 API. Both the json and text formats are supported. For more details, we refer to the sgminer api documentation.
The miner also includes a Claymore miner compatible API with support for a subset of the API.

For reporting bugs and/or for features requests, please open an issue on this project's github issue tracker.

For example command lines please see the batch/shell scripts in the miner download packages.
Miner command line options are available

Team Red Miner v0.8.1
Key highlights:

• Big Navi support added. This is just a basic support release for all supported Navi algos (ethash, kawpow, mtp, nimiq).
  o Kernels are close to or identical with Navi10 A-mode (ethash) and default modes for Navi10 (kawpow, mtp, nimiq).
  o Please read the updated ETHASH_TUNING_GUIDE.txt for a short tuning section at the very end of the file.
  o Big Navi should run in A-mode for ethash (default choice), not B-mode. Read tuning guide for more info.
  
  
• Eth+zil mining: new pool strategy 'min_epoch' added for switching between plain eth and eth+zil pools. See the example start script start_zil_eth(.bat/.sh) for usage.
  
  
• Ethash: Navi display gpus now using A-mode by default to prevent allocation issues, especially on Windows. Navi gpus without a monitor attached will continue to default to B-mode.
  
  
• Statistics: now proper handling of negative temperatures under Linux.

Changes in v0.8.0

Biggest release in a long while with rewritten ethash kernels and new mining modes for all gpu types!

Users are highly(!) recommended to take a few minutes to read the 0.7-to-0.8 migration guide and the new ethash tuning guide. Key highlights:

• Polaris: Efficiency and slight hashrate increase. B-mode reintroduced for added hash. B-mode must be enabled with --eth_aggr_mode or --eth_config=Bxxx.
• Vega 56/64: greatly improved base kernel for efficiency. New B-mode that can shave off additional 1-2W on top of the A-mode kernel. B-mode must be enabled manually with --eth_config (--eth_aggr_mode does not apply). Tuning numbers have changed - do NOT keep your old static --eth_config values.
• Radeon VII: huge boost with its new C-mode but requires a special Linux setup. Can now do 100 MH/s on most air cooled VIIs. See tuning guide.
• 5700/5700XT: can shave off as much as 8-9W(!) of power using the new B-mode and dropping core clk+voltage. B-mode now the default mining mode. Unless you retune your core clk+voltage you will see a tiny power draw increase instead and not benefit from the upgrade, so read the migration guide.
• 5600XT: new B-mode has a much smaller effect. A-mode remains the default mining mode. See new tuning guide for more details.
• The dag cache is NOT compatible with the new B/C-modes. ETH+ZIL switchers have to choose between caching the epoch 0 dag and using the new mining modes.
• Ethash 4GB kernels NOT rewritten in this release, performance remains the same as in 0.7.x.
• See the migration guide for hashrate and power draw comparisons between 0.7.21 and 0.8.0.

Release notes:

• Ethash: VII kernel rewrite and new C-mode with boost feature (see guide).
• Ethash: Navi kernel slight optimization and new B-mode for lower core clock and power.
• Ethash: Vega kernel rewrite and new B-mode for lower core clock and power.
• Ethash: Polaris kernel rewrite and new B-mode for slightly higher perf.
• Ethash: added share processing timeout and default for Binance pool (see --pool_share_limit_ms).
• Claymore API: fixed leak that stopped serving requests after 32k api calls.
• Claymore API: added password support (see --cm_api_password).
• Logging: added log rotation support (see --log_rotate).
• Logging: log files now contain the miner welcome message so the version is stored.
• Kawpow: now mining ok at MiningPoolHub even though their seedhash is broken.
• Fan control: added min/max fan speed range (see --fan_control).
• General: added argument to turn off duplicate pci bus id filtering (see --allow_dup_bus_ids).

Changes in v0.7.23

None - discarded as internal test version.

Changes in v0.7.22

Highlights:

• NAVI KERNEL REWRITE! Over the last month we've been working on new kernels. The first one released is for Navi. The main feature is lower power consumption, hashrate will remain about the same but depends somewhat on clocks. NOTE: please let the miner retune any existing --eth_config arguments for all Navi gpus, the new values will be significantly lower.
• Claymore API now supported, meaning you can use EthMan to monitor TRM rigs.

Release notes:

• Ethash: Kernel rewrite for Navi. Should now be more stable and use less power. Vega/Polaris still in the works.
• General: Slightly reworked init procedure again to address some rigs running better on <= 0.7.18 than >= 0.7.19.
• General: Added Claymore compatible API, see the --cm_api_listen option.

Changes in v0.7.21

Quick release that addresses situations where Ethash with capped DAG on 4GBs would crash after 5-10 mins when running at 4078-4080MB.

Release notes:

• Ethash: improved probability for high (4078-4080MB) ethash 4GB capped allocation running stable over time.

Changes in v0.7.20

Highlights:

ETH is now approaching the start of the 4GB death with the upcoming switch to epoch 382. TRM was the first miner to add support for mining with 4GB gpus with a partial DAG, here called "extended mining". However, it has always required manual configuration. This release adds a default conservative cap at 4072MB for DAG storage on 4GB gpus for out-of-the-box execution of the miner. For maximum performance, miners are still advised to manually tune their rig(s) with the --eth_4g_max_alloc argument. Most rigs runs stable with a higher value than 4072, which makes a significant difference for upcoming ETH epochs.

Release notes:

• Ethash: added default capped DAG allocation for 4GBs at 4072MB (see --eth_4g_max_alloc).
• Ethash: bugfix for crashes using --eth_dag_cache on 4GB gpus.

Changes in v0.7.19

Highlights:

• Ethash solo-miner share high-score list added, use --high_score to enable.
• Ethash single buffer dag for a small power save. Only available on recent drivers and should in theory always be an improvement. It is not verified 100% stable yet and therefore not the default in this version. Enable with --eth_dag_buf=A to test.
• Miner gpu initialization procedure rewritten. The init procedure should now hopefully be much more stable, especially on Navis in general and even more so for 5600(XT)s.
