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

[georat72]

Any plans for c31 on 4gb cards?

[V1T]

Please add a GPU temperature limit option.

and Power Limit settings

[nebutech]

Have just tried AE on nicehash and got 100% rejects with hotfix version. So does this miner support nicehash or not?

Current version has a bug, and is not compatible with NiceHash recent change of protocol on cuckoocycle, will be fixed in the next version soon.

Any plans for c31 on 4gb cards?

No plan for support cuckoo series algo on 4GB cards.

Please add a GPU temperature limit option.

Will be added in the next version.

and Power Limit settings

Do no find a way to do a power limit on nvidia cards. Please use MSI Afterburner or alternative tools for GPU tuning.

but c31 on 8GB win 10 would be nice?

[nebutech]

but c31 on 8GB win 10 would be nice?

8GB card on win10 only has 6.8G VRAM available to use.

Shrink down Grin31 memory usage to this low will cause significant performance drop, which makes mining Grin31 not profitable compared to other coins.

So, still a NO for Grin31 on win10 yet.

[georat72]

Thank you, clear enough

but c31 on 8GB win 10 would be nice?

8GB card on win10 only has 6.8G VRAM available to use.

This is not really correct.

Win10 1903 here, drivers 430.86 - 1070 card with NO monitor attached shows around 104Mb used out of 8Gb.
1080ti with monitor shows 870Mb used out of 11Gb, but that's the main card with a lot of stuff running right now (not mining).

BTW, could you please implement 10Gb solver for 1080Ti cards?

You cannot determine how much VRAM is able to use (malloc by GPU program), win10 WDDM driver model reserves about 15% VRAM.

When you see 8000M GPU spare, the amount of VRAM you can actually use in GPU program is ~6.8G.

However, nvidia mining-specific cards use TCC driver model (same as Nvidia Tesla cards), which do not have those limit.

Cards like P104 8G version can mining Grin31 on Win10.

NBMiner already has a 10GB version solver for Grin31, IF you use win7 or linux.

@nebutech, thanks. Not like I understood anything, but I guess you know better

New version comes.

v23.3:

- Fix mining AE (cuckoocycle) on NiceHash.
- Add option to set a temperature limit on GPU.

How to set a temperature limit?

[Vadisss]

Should the temperature limit be shown in the miner window ? I have not shows.

For those wondering what's the performance of a 2080 Ti with BTM+ETH, you have to tweak the secondary intensity and see what's best for you.

In my case, I find the sweet spot to be 5-7, which gives me about 12kh/s BTM and 45mh/s ETH at 90% PL and +1000 mem, haven't tried 100% PL but probably it's about the same. If you increase the intensity you gain more hash in ETH but less in BTM.

It's pretty good but right now it's best to focus on just BTM.

Hi all,

Been racking my brain for weeks trying to figure out why my 2080 ti's crash mining grin31...I have a couple machines with 1080ti's and they run wonderfully, but this machine has 3 cards, 1 x 1080ti and 2 x 2080ti's and within a min or so of firing up the miner one of the 2018ti's crash - fans go to full bore and 0's show in afterburner.   The machine is quite powerful with an 8 core cpu and 64 GB of RAM.  I've got VRAM set to 80GB, my machines with 6 x 1080ti's runs great with 70GB...Power supply is probably on the edge at 850 watts, but I monitor the usage and run the cards at 65%..And the wattage stays below 700 ish on the machine...I've uninstalled drivers, swapped cables, tried different drivers, lowered the clocks...Any tips on what else I could try would be greatly appreciated.  It will mine x16r for weeks without an issue...It's not just this miner, it's all miners for grin31, but I posted here because this miner is the best which means this thread probably has some real smart folks...

Are you using SMOS? Have you tested it without the 1080ti? I had this issue in February when I tried to run a rig with two 20-series cards (2080ti + 2070) and four 10-series cards (1080ti x2 + 1080 x2) on SMOS. I tried every configuration I could come up with and every time a 20-series card was mixed with a 10-series card, the fan on one or more of them wouldn't work right and that(those) card(s) would crash. I had to split the rig, which added 40-50W, but back then it was still more profitable in my situation to run the 1080s on Grin31 instead of Grin29. When you consider the extra electricity, it is now more profitable for me to run all the cards on one rig using Windows and just have the 2070 and two 1080s mining Grin29. I have no real technical expertise here and no idea if this is just an SMOS issue or more broadly a Linux issue.

Thanks for the reply...I should of mentioned these are Windows 10 machines...I did try running it on just the 2080ti's but no luck...the other machines with no 20180ti's have 0 issues...So strange.  I've swapped risers and cables...Might be the power supply but it runs so many other algos without issue...I've tried running them at 50% and still they crash.  I'll try like you said, run Grin31 on the 1080ti and 29 on the 2080ti's

Okay. In that case, if you have another power supply, I'd try it because the power usage on Grin jumps around alot, but I would think it would run a little bit before that caused an issue. Hopefully you can get it figured out.

Hi,
how do you set the starting diff for grin31? it starts at 16 and eventually goes down to 4, but I'd like to start it at 4 off the bat, thanks

it might depend on pool, usually, you can enter the diff via the password, something like that:
-u address.worker:d=4
