v39.6(2021-10-27)
- `optimize`:`ethash` LHR mode significant improvement:
- default LHR mode changes to `-lhr-mode 1` for LHR GPUs
- default values of LHR mode increased, `-lhr-mode 1` -> 74, `-lhr-mode 2` -> 71
- added 3 new options for LHR auto-tuning control, at most cases you don't need to change:
- `-lhr-reduce-value`: the amount to reduce `-lhr` value on a single `-lhr` tuning. defaults to `0.5`.
- `-lhr-reduce-time`: When LHR lock is detected, and the time since the last lock exceeds this value, the `-lhr` reduce will not perform. defaults to `15`, which means 15 minutes.
- `-lhr-reduce-limit`: the maximum number of times to reduce `-lhr` value, defaults to `6`.
- Typical hashrate: 3060Ti LHR on defaults options, 45.5 MH/s @ mem+1200 (win10)
- `feature`: `ergo` also adapts the 3 new LHR options.
- `feature`: add `-cmd-output` option to specify command line outpu to `stdout` or `stderr`, `1=stdout`, `2=stderr`, defaults to `2`.
- `feature`: disable SNI extension for ssl connections by default, can be enabled with `-enable-sni` option
- `delete`: `cuckatoo` & `cuckatoo32` support
v39.5(2021-09-24)
- `feature`: `ergo` new LHR mode for mining ERGO, enable it by manually adding `-lhr` option
- For GPUs with Hynix GDDR6 memory, LHR mode is not recommended for the poor performance.
- For GPUs with non-Hynix GDDR6 memory, e.g. 3060 3060ti 3070, start trying with `-lhr 85`
- For GPUs with GDDR6X memory, e.g. 3070ti 3080 3080ti, start trying with `-lhr 100`
- When mining lock is detected during ERGO mining, miner will automatically decrease `-lhr` value by 0.5, and continue mining. max decrease times is 10, which sums to 5.0
- `optimize`: `ergo` Lower power consumption on Nvidia GPUs.
v39.4(2021-09-21)
- `fix`: `octopus` Fix error hash issue.
v39.3(2021-09-18)
- `feature`: `ethash` new low power LHR mode, add `-lhr-mode` option.
- `-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 `-lhr`changes 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+
39.0(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.
- `-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.
