NBMiner v42.2, 100% LHR unlock for ETH mining !

[miner29]

41.4 beta is out and unlocks 90% of 3080 12gb (100mhs) and 3050 (27mhs)

Great Stuff!

hi im having probs with my 3070ti,s all works but then randomly a card will just stop even though they worked great with other versions, what drivers should i use latest or what cheers.

I have a similar issue with my RTX 3060 12GB rig on v41.4 & v41.5, where all nine cards will mine at 47 Mh @ 110w for a few hours. But then, one of them will drop to 16-17 Mh @ 110w until I reboot the rig. Restarting NBMiner doesn't work. At least Minerstat supports auto-rebooting when the hashrate drops.

I have confirmed this isn't a memory clock or stability issue with the hardware itself. It happens even when mem clock is +0 MHz. The underlying OS is Ubuntu 18.04.5 LTS while the driver is 510.60.02

happens in windows also a few times for me.  only reboot fixes it.

On my all LHR rig, I can lock the core on each GPU by passing the following parameters:

--cclock @1350,@1200,@1200,@1400,@1200,@1350,@1200

It has the following GPUs:

0 3070Ti
1 3080Ti
2 3080Ti
3 3060Ti
4 3080
5 3070Ti
6 3080Ti

However, I also have a rig with a mix of 1000, 2000 and 3000 cards as follows:

0 1070Ti
1 3060
2 1070Ti
3 2080Ti
4 3080Ti

I want to lock the core on GPU 4 @1200.  How do I do that since some of the other GPUs don't support core lock?

EDIT:

Like this:

--cclock ,,,,@1200

#### v42.1(2022-05-24)

- `fix`: `ethash` Linux LHR unlocker can not unlock on certain GPUs.

#### v42.0(2022-05-23)

- `feature`: `ethash` Extend LHR unlocker work with old driver versions. All previous drivers should work until `515.x`.
- `fix`: `ethash` Improve LHR unlocker stability under Linux.
- `optimize`: `ethash` small hashrate improvement on Nvidia GPUs.
- `feature`: Add `GDDR6X` memory temp in summary table for Linux.
- `feature`: Add `GPU RAM type` and `GPU RAM vendor` in log.
- `feature`: Add Nvidia driver versoin in summary table.
- `feature`: If `Overclock` applies through `nbminer`, reset settings to stock when miner exit.
- `feature`: `-mt` option on windows does not require custom driver anymore (admin priviledge is required).
- **`NOTE`: NBMiner versions older than v39.5 (not included) will run into issue when ETH reaches `EPOCH 520` (Approx mid September). Please make sure to upgrade to a newer version before that if ETH is still with POW.**

Hi folks!

does anyone knows why if the power limit is configured, the consumption never comes to this value?
 
HIVEOS: 5.10.0-hiveos #83

Thanks for your great help!!!

What is the right way to force nbminer to use backup mining pools? I tried this line, but it doesn't work:

Code:

nbminer -a ethash -o pool -u name -o1 pool1 -u1 name1 -o2 pool2 -name2 -log

I'm still getting this error:
ERROR - No share accepted in 30 minutes. Something is wrong, restart miner.

Hello,
Please tell me what could be the problem - I use a miner for Windows, an LHR video card, when I open the Evernote program, the hashrate drops (from 61 to 38 for 3060 ti and from 81 to 49 for 3070 ti.

Why does this happen and how can I fix it? Thanks.

NVIDIA has reportedly removed LHR from its newest drivers
https://bitcointalk.org/index.php?topic=5417089.msg61118737#msg61118737
NVIDIA's Linux driver 520.56.06 & Windows driver 522.25 do not seem to trigger LHR when mining with traditionally locked algorithms like Etchash & Autolykos.

etchash: Add support for NiceHash ETC pool.

Is there a way to disable LHR within miner?
Because even with latest Nvidia drivers, miner still applies LHR mode automatically.

Does it affect the hashrate?
Usually these settings are automatic.

Probably yes, because LHR is not 100% unlocked,
and hashrate is low compared to other miners.

Usually these settings are automatic.

Yes, and automatically applies some LHR modes which is unwanted that hurts the hashrate

Yes it will. Defeating LHR requires running a dummy process on the GPU. Without LHR the dummy isn't needed but running it
will steal processing time from the miner process.

Edit: dual mining also serves to defeat LHR if one of the algos is immune. In this case there is no dummy so dual mining may not be
affected.

Hi NBminer can you please add temperature target both amd and nvidia. I want set temp target exapmle target temp:@45,@50 something like that. If possible for available gpus memory target too.thanks for miner

[batsonxl]

Please devs add temperature target. I started loving nbminer it is stable and working good both amd and nvidia. Just please add temperature target.

[sxemini]

Please devs add temperature target. I started loving nbminer it is stable and working good both amd and nvidia. Just please add temperature target.

This miner is dead. Why you use this? So many better miners out - with no inflated hashrate.

Yes i think you are right it is dead miner. What can you suggest for both nvidia and amd with target temperature stable and proxy support clock memory support. Sorry i wrote to many things

Hello. Today I made a PR for with information about our mining pool. How long does it usually take to process requests? I see that there are very old requests and they are not closed.
