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

[pedro77pl]

I have problem with Bytom mining performance. My rig used to mine with 4x1080Ti. Performance was ok, almost 5K hash per card. Now I changed 2 cards and have 2x2080 and 2x1080Ti in the same rig. The 2080 performance is as expected, but sadly 1080Ti performance halved! I tried to run both pairs of cards as separate threads, but it's the same. Any help on this?

There is a confirmed issue that mining BTM with mixed 10 series and 20 series cards, which would cause the 10 series cards has much lower hashrate than previous versions.

Will be fixed in next version.

Thank you! Can't wait! 2080 series performance with BTM is just plain amazing.

Make support Cuckaroo29s for Swap (XWP).Thanks

Try the new v20.0 version to see if it fixes your problem.

What the speed for RTX 2060 on ETH+BTM mining?

Thanks, v20.0 works with RTX 2060.

What the speed for RTX 2060 on ETH+BTM mining?

Local/console reported speed is around 7.3k for BTM. This is running on Linux (Ubuntu) with a 125 Watt power limit, clocks at core +150, mem -2000 (yes minus 2000 on mem). Need to run it for around a day to check on pool side for actual hashrate.

v20 looking veeeeery nice on Grin c31. Bravo.

Hey Nebutech, great work.  What is the minimum memory for C31 with your miner?  Does 8gb card work on windows 10? or is it only 11gb?  Also what is the minimum and maximum parameters for cpu intensity?

8GB cards only work under win7 and linux.


--cuckoo-intensity <intensity>

Set intensity of cuckoo, cuckaroo, cuckatoo, [1, 12].

Set to 0 means autumatically adapt. Default: 0.

Pagefile=swap file for Linux?

Anyone tested lower RTX cards like the 2080,2070 and 2060?

I've only tested BTM using v20.0, but my 2070 gets 9030 h/s at stock settings (1665core/6800mem/100%power on my card). With power set to 80%, the hashrate drops to about 8350 h/s. I was happy with that, so haven't played around with lots of settings.

program crashes when some gpus fail to start.
is it possible to fix this?

[nebutech]

Use option '-d 0,1' to select the first 2 cards, for example.

THX.
if I don't know which gpu will fail, can I select all cards but only run those normal cards?
the thread that control the fail cards can sleep and restart every 5 minutes.

BTW, i find the program detect the cards in a different order with the nvidia-smi.
this causes some trouble for selecting device.
for example, I have an nvidia-smi result as below,
0  GeForce GTX 1080
1  GeForce GTX 1070
2  GeForce GTX 1080
3  GeForce GTX 1070

but nbminer detect the device# as below,
0  GeForce GTX 1080
1  GeForce GTX 1080
2  GeForce GTX 1070
3  GeForce GTX 1070

[cudapop]

By default nvidia-smi detects card order according to PCIe lane, while CUDA programs detect card order by performance. To switch CUDA to detect according to PCIe order so it matches nvidia-smi, set the environment variable "CUDA_DEVICE_ORDER" to the value "PCI_BUS_ID" before running the miner.

For example, for Linux systems use:

export CUDA_DEVICE_ORDER=PCI_BUS_ID

@NebuTech devs, maybe you can add the above in the shell/batch startup files.

Currently NBMiner do not has the option to ignore failed cards.

NBMiner uses GPU order in CUDA runtime instead of Driver runtime, these two can be different in some rigs.

Thanks to @cudapop. I'm taking this into future change plans.
