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

[Bucheran]

v21: CUDA Error: no kernel image is available for execution on the device (err_no=209)

2080Ti, latest drivers 419.35
 
v20: works fine!

Any suggestions?

same problem

Sorry guys, v21.0 does not support 20 series cards for now.

BTW on linux i'm getting about same (well, pretty much EXACTLY SAME ) hashrate on 1060s as on win10.

I guess I should be getting lower as other miner sw authors claim the win10 can't use all the gpu memory? But definitely can't get over 3 per GPU. Definitely not 3.15 - still better then bMiner thought as he claim 3.3 and I can get 2.6 or maybe 2.7 max.
Can CPU be bottle neck? I do run the cheapest celerons that were available at the time. Maybe it is because of Micron and not Samsung memory cards?

I think this performance is on par with gminer. Both gMiner and bMiner can't start on windows10 at all thought (because of the GPU memory limit they claim).

What's your CPU usage when mining?

There is an option '--cuckoo-intensity', you can try tune it up to lower CPU usage.

new version shuts down 2 of my GPU for whatever reason i dont know. displays no error or msg. just stops using the memory and turns the gpu to min power i have decreased the memclock and it still happens. all the time. same GPUs. never happened before and never had problem with other miners or versions.

Cuckoo series algorithm implementations could cause an instant high power consumption, the peak power consumption could exceed the power limit of GPU (150W for 1070). This problem become more serious as the hashrate of miner goes higher.

Check your power supply, make sure the power delivery has 20% more than what the average mining cost.

like i said. never had this issue with past NBminer version or any other software. the PSU is 1600 watt psu with 6 GPUs limited to under 110 watts each. power draw at wall is 700 watts. some issue with new version. been mining grin since main net launch

Thanks for the report.

I checked code, this is a bug which will happen when using backup mining pool urls.

I will fix in the next version.

Please use only one url for now.

My apologies.

What is the speed of 1060 6g?

What is the speed of 1060 6g?

Slightly lower than p106, cause p106 usually has higher freq than 1066.

More grin weirdness from me.
I quickly tried on hiveos (mineros.cn registration still does not work)

On rig - newer drivers and kernel does 2.9, other exact same, but i think stable hiveOS so bit older drivers and kernel (and also unbootable from usb on biostar with windows ssd present ) 2.7 mostly.

Do you think cuda version could be the issue or something else?

Also second one does have bit higher mem oc, but lower g/s.
On linux there is no undervolting for nvidia cards, at least no publicly known, so i do use power limit, but hiveOS is quite nice that it is easily readable from single screenshot.



I will not post other miner performance on rig with lower performance in NB miner here as hiveos does not have gminer 1.15 which may fixed some hashrate issues.

What is interesting is load average that is lowest in NBminer with no apparent negative effect on hashrate, so I would guess that CPU is not bottle neck after all.


Bminer for comparison:

not comparing pool hashrates!

As far as I know, the driver version has big affect on mining Grin & AE, especially on windows.

The recommend driver version for Win10 is 399.24 (the last 3xx driver version).

Comparison on hive os - current major public grin29 miners, both 3xx and 4xx nvidia drivers compared

gminer 1.35


bminer 15.2


nbminer 21

the 3xx driver starts faster, but then settles down



sorry for the size of the images :/

This does NOT compare pool side hashrates!

Thanks for detailed information.

Keep improving nbminer.

Hello
I just found your miner.
I have a 2080 ti
Overclocking it I get about 18.70 kh/s for BTM
This is really good.
Any chance there will be further updates for BTM Tensority algo ?

Edit: Using windows 10 and the latest nvidia driver available.

Edit2: Also cuda 10.1 was released recently and there are updates for tensor cores in it which improve performance.

Do not have an update plan for BTM recently.

The main reason is Bitmain already launched a new ASIC miner for BTM (Antminer B7).

Besides, thje price of BTM really do not encourage developer to do futher development, the difficulty to put Tensority algo near theoretical limit is actually much harder than most other algos.

Hello,
Thanks for your miner Nebutech.

Using RTX tensor is a really good thing.
It's a shame that with the upcoming ASICs it will put a little bit of shadow on it, but your original job is well done.

However put it perspective, as usual, all the first batch Asics are already mining before shipping, I don't think it will get unprofitable that fast on an RTX thanks to your miner.

RTX cards will always have resell value which an ASIC don't have, so I think GPU mining still have a small future

Anyway I'm happy to mine with your NBMiner with 2x 2080ti and your fees is rightfully claimed for your hard work.
Thanks again.

Allowed.

Mmm pool side show 10kh/s less then what miner shows  and when it does show near what miner shows it slowly drops. On BTM
