lolMiner 1.25
lolMiner goes CUDA!
Added a real Cuda back-end for better Nvidia GPU support on Ethash. Features:
- Supports Maxwell to Ampere GPU generations.
- Two different mining kernels. Use --mode a (faster) --mode b (better energy efficiency) to select between the two. The selection can be done per card via a comma separated list. In mixed system select 'a' for skipping over the AMD cards.
- Both kernel modes need less energy and perform better then in 1.24a
- Reduced internal latency for less stale shares
- Reduced CPU load when mining with Nvidia cards
- lolMiner works now without OpenCL driver installed
- In case of mixed rigs AMD GPUs will use OpenCL while Nvidia cards use Cuda
- ZIL cache feature fully supported (and stable)
- Temperature stop & Zombie mode is currently not supported
Further Changes (over 1.24a)
- Added Ethash, Beam Hash III, Grin Cuckatoo 32 and Cortex kernels for RX 6700
- The Ethash stratum interface will now try to run up to three attempts of reconnecting before switching the stratum mode
Bug fixes
- Fixed "Warning: index out of bounds" error when switching from ETHPROXY to ETHV1 stratum mode. This might solve problems with some pools on connection loss.
Recommendations for Cuda backend
- Recommendation: When using lolMiner on Nvidia cards only use "--watchdog exit" mode and run the miner in a script that will automatically restart it on closing.
- For ideal efficiency fix the core clock, do not use the offset functionality. Recommended values for selected GPUs:
| GPU | Range |
|---|---|
| 2070 | 1000 - 1050 |
| 2080 | 1110 - 1160 |
| 3060 (1) | 1070 - 1120 |
| 3060ti | 1300 - 1350 |
| 3070 | 750 - 800 |
| 3080 | 1010 - 1060 |
