Let’s consider setting up a .bat file of a program for Ravencoin mining.
Decryption of the contents of the .bat file
teamredminer.exe– indicates which application will be launched. This file must be in the same folder as the .bat file
-a kawpow– specify the algorithm for mining. For Ravencoin, we specified
cnr, while for Zcoin, we would specify
us.rvn.minermore.comafter the long construction
-o stratum + tcp: //we indicate the pool address
: 4501– after specifying the pool address, put a colon and write the pool port. The address and port can be found on the pool itself. Usually under Get Started or Help
-u RKAeArXkWLNERjWo5YF3R1xFnYCwKf11sX– specify the wallet that will be used for mining. In our case, this is Ravencoin.
-p x– the p command means a password. On the minermore pool (as well as on 90% of all pools), a password is not required, so we write x
pauseis an optional command. It is only needed so that the program does not immediately close in case of an error, but displays it.
Ready example (don’t forget to change the wallet to yours!)
teamredminer.exe -a kawpow -o stratum+tcp://us.rvn.minermore.com:4501 -u RKAeArXkWLNERjWo5YF3R1xFnYCwKf11sX.trmtest -p x pause
Changes in v0.7.16c
BETA RELEASE – small fixes for Turtlecoin’s new algo chukwa2.
- Chukwa2: fixed kernels loading for Radeon VII gpus.
- Chukwa2: fixed mem footprint for 2GB gpus.
Changes in v0.7.16b
BETA RELEASE – adds Turtlecoin’s new algo chukwa2. Not tested as rigorously as other versions. Only use for the Turtlecoin fork.
NOTE: Navi gpus are NOT supported on chukwa2 for now. Support will be added if there’s sufficient interest.
- Added algo trtl_chukwa2 for the Turtlecoin fork on 2020-10-22.
Changes in v0.7.15
Small bugfix release.
- Ethash: fixed bug for ZIL (epoch 0) mining on 4GB gpus (bug appeared in 0.7.14).
- Ethash: reverted to v0.7.10 kernels for stability purposes except for ROCm-based rigs.
Changes in v0.7.14
This release wraps up our work for 4GB gpus mining ethash. Linux 4GB are verified to mine up to and including epoch 381 on drivers 18.50/19.30/19.50/20.10. After that, we have added support for extended mining from epoch 382 and up. Extended mining is a trade-off between hashrate and being able to mine at all, gpus will lose additional hashrate for every extra epoch. Please see the Linux section in the ETHASH_4GB_HOWTO.txt for more details and instructions.
- Ethash: verified Linux support for 4GB gpus up to and including epoch 381.
- Ethash: added support for extended 4GB mining from epoch 382 and up.

Changes in v0.7.13

Changes in v0.7.11
- Ethash additions: printing share diff in GH (always enabled), hashrate watchdog (see –eth_hashwatch).
- Better debug support: –long_timestamps, –pool_debug.
- We’ve found certain motherboard/bios combinations that due to kernel and/or driver bugs have issues with the first or last gpu in rigs. If you see excessive hw errors reported on a single gpu, and switching around gpus still always generates errors in the first or last gpu, try using –eth_dag_alloc_patch.
- Added DAG allocation patch under linux for certain mobo/bios combinations (see –eth_dag_alloc_patch).

- Turned off compute mode checks for non-Polaris gpus.
Changes in v0.7.10
- Ethash 4GB rigs, especially on win, should use –eth_alloc_epoch=N with N being the max epoch that the gpus can allocate. This will avoid DAG reallocation issues.

- Added default log filename (trm__<yyyymmdd_hhmmss>.log)
- Added ethash forced initial allocated epoch ( –eth_alloc_epoch=N). Note: HIGHLY recommended for 4GB rigs.
