New version:
#### v33.6(2020-11-21)

- `optimize`: `octopus` improve hashrate: +10% on 16 20 30 series Nvidia GPUs, 27.5M on 1660s.
- `note`: `octopus` From this version, GPUs that has higher core performance than memory performance, need to overclock memory to get higher hashrate, e.g. 2080 3070

#### 33.5(2020-11-21)

- `optimize`: `octopus` improve hashrate: +90% on 16 20 30 series Nvidia GPUs, at least +100%  on all other GPUs

New version update:

#### v33.4(2020-11-12)

- `optimize`: `octopus` improve hashrate: +35% on 16 20 30 series Nvidia GPUs, +20% on all other GPUs
- `new algo`: `etchash` for upcoming ETC upgrade
- `feature`: add effective pool hashrate on console & api, 10min 4h 24h.

New version v32.0:

- `new algo`: `beamv3` for mining `BEAM` with Nvidia 3GB+ GPUs
- `new algo`: `cuckatoo32` add support for Nvidia 6GB GPU
- `optimize`: `ethash` for AMD RX 4xx, 5xx, Vega series 8GB+ GPUs
- `feature`: `ethash` support mining up to epoch 800

Who know how to disable Power jump's when Generate new cuda kernel on Ravencoin KawPow algo? I just need stable power line.

`Genarate new cuda kernel` means CPU is doing background work build kernel for the next period, while GPUs are also working, so it will have an extra CPU power usage that consumes power.

If you want to flatten the power curve, try limit the CPU TDP or frequency.

new version with Grin C32 support
Tried C32, got device out of memory error on Win 10 with 8GB 1070s, while gminer works fine there. Not sure what you meant by "cuckatoo32 for Grin32 on Nvidia 8G above GPUs" in the release notes. Is that "8GB or above" or "above 8GB"?

Check `requirements` section in readme, C32 under Win10 need 10GB or avove GPU memory to run, 8GB is fine for Win7 & Linux.
support mining C32 under lower GPU memory is pointless cause it's profitablility is definitely lower than ETH.

Good afternoon. I canít start the miner nbminer-nebutech-v30.2 for mining algoritm ethash, Ethereum (ETH) on pool europe.ethash-hub.miningpoolhub.com. port 20535? 17020. Answer: is it possible to use the miner nbminer-nebutech-v30.2 to mine the algorithm ethash on pool miningpoolhub.com? If so, please send a file .bat for the sample for this miner.

Using `nicehash+tcp` instead of `stratum+tcp` in '-o '

what the best memory-tweak for 1070, 1070ti?
1 or 6 or individual?

if miner can be stable in mt 6, higher mode = higher hashrate.

On Nvidia devices I have error: C:\Windows\SYSTEM32\nvcuda.dll
Devices initialize failed
No GPU available for mining
Mining program unexpected exit
AMD GPUs are working well.
Your miner is not working on all CUDA versions/Nvidia drivers.


Try reinstall a WHQL driver.

--no-watchdog    Is not working for kawpow ?

on linux system. if you want to use '--no-watchdog', you need to manually set environment variable `LD_LIBRARY_PATH=/tmp`.

 Smiley v30.2 released
- `windows`: Auto install driver if `--memory-tweak` is set and driver is not installed.
- `windows`: Fix `driver install failed` issue on some windows rigs.
- `kawpow`: Fix `duplicate share` issue on some pools.

Hi
1). What is the commission charged for using the miner when mining Ethash?
2). Does the commission change when using a tweaker?

With or without tweaker, devfee of ethash has changed to 1%, since 30.0.

amd polaris kapow compatible?

kawpow works on AMD for polaris and above.

New version released.

 v30.1(2020-05-03)

- Reduce `ethash` `kawpow` startup time.
- Fix a possible crash on certain rigs of reason `invalid kernel image`.
- Do not apply memory tweak if `-mt` is set to 0 on corresponding gpu.
- Print system information on start.
