Change Log

v39.3(2021-09-18)

feature: ethash new low power LHR mode, add -lhr-mode option.
- -lhr-mode 2 is the default LHR mode, which is the new lower power mode.
- -lhr-mode 1 changes LHR mode to old version, which is the same as v39.2
- -lhr-mode 1 is suitable for only power limit bounded GPU, can achieve higher hashrate than mode 2
- -lhr-mode 2 is able to achieve lower average power and temperature. espacially suitable for GPUs with gddr6x e.g.3070ti, 3080, 3080ti. Power consumtion is fluctuating in this mode, better be used with locked core clock.
feature: -lhr support decimal value
feature: for LHR GPUs, when mining lock is detected, miner will automatically decrease -lhr value by 0.1, and continue mining. max decrease times is 10, which sums to 1.0
fix: higher CPU usage when set --share-check 0

v39.2(2021-09-01)

feature: ethash added LHR lock detection and recovery in LHR mode.
feature: added memory temperature display (if available) for Nvidia and AMD GPU under windows.
fix: ergo more robust protocol handle.

Note: LHR mode requires NVML library to work, please make sure the driver is installed properly and do not add -no-health argument.

v39.1(2021-08-21)

optimize: ethash improve hashrate of LHR mode 1 - 2%，default value of -lhrchanges from 68 to 69，manually set to 70 is also very promising.
fix: LHR mode support on windows driver 471.11
fix: kawpow issue of v39.0
fix: Radeon vii issue on windows driver 21.6.1+

v39.0(2021-08-15)

feature: ethash New LHR mode for ETH mining on RTX 30 series LHR GPUs, supports Windows & Linux, able to get ~70% of maximum unlocked hashrate.
- This mode can be tuned by argument -lhr, only works for ethash right now.
- -lhr default to 0, meaning even if -lhr is not set, LHR mode with -lhr 68 will be applied to LHR GPUs if certain GPUs are detected.
- Tune LHR mode by setting -lhr <value>, a specific value will tell miner try to reach value percent of maximum unlocker hashrate, e.g. -lhr 68 will expect to get 68% of hashrate for same model non-LHR GPU.
- Higher -lhr value will results in higher hashrate, but has higher possibility to run into lock state, which will leads to much less hashrate.
- A good start tuning value is 68, which has been tested to be stable on most rig configurations.
- -lhr value can be set for each GPU by using comma separeted list, -lhr 65,68,0,-1, where -1 means turn off LHR mode.

v38.2(2021-07-27)

fix: AMD kernel error on certain GPUs with 21.6.1+ drivers under windows.
