Please keep mining discussion to subreddits such as /r/EtherMining or r/GPUmining. Note that Ethereum PoW mining is expected to end within the next 6 - 9 months.

tldr; Nvidia has limited the mining capacity of its new graphics cards in pursuit of eliminating the interest of cryptocurrency miners around its products that are mostly designed for gamers. However, some miners have reported that they were able to unleash the mining power that Nvidia represses on some of its graphics cards using NBMiner and Gminer, two programs dedicated to ETH mining. *This summary is auto generated by a bot and not meant to replace reading the original article.

This is not true. Workaround to use entire available memory bandwidth of the card and not trigger the lock: mine two different coins (something like 35% eth, 65% ergo or raven, but it should improve to 50/50 in future versions). Card is maxed out, but it does not mean that profit is the same as earlier versions of the same card (cards without hash rate limiter, mining eth with 100% of it's capacity).

Yesterday i said the same on other post and I'm gonna repeat it, why the 70% barrier don't go up since this was first released? I tested my 3080ti with nbminer and let run for more than half an hour at \~110mh/s submitting shares with no problem and the pool register the same hashrate as the miner but with one problem, the power consumption jumps back and forth between 111w and 260w, not sure if this will damage the card on the long run. This makes me believe that it should be possible to get more of the card than the 70% sable, so why can't we get like 75% or something like that unlocked.


NotPresidentChump

I’d have no problem running that card steady state at either of those currents but having it cycle back and forth I feel like something, voltage controller, PSU, etc. is gonna give out.


JP8296

Yeah that's my concern, but like i said, the miner can do it, so it fell like it should have more progress done right now.

How are you getting those hashes on a 3080 ti? Which specific card do you have? I tried my 3080 ti EVGA xc3 and I'm only able to get a out 72 mh/s, at around 230 watts using nbminer.


JP8296

MSI 3080Ti Suprim X. First set the miner at LHR 70% and fine tune it on afterburner to get the most of the card then set the miner to LHR 100%, it starts at \~120mh/s but is settles at \~110mh/s at LHR 99%, problem is the power consumption that starts jumping between 111w and 260w.


BobisaMiner

Interesting, poolside hashrate is 110Mh/s? Impressive.


JP8296

You can see it here, not 110mhs at that momente but you get the point. https://imgur.com/a/koY4hIN


BobisaMiner

If it maintains that hashrate for at least 24h(poolside) then it's an awsome result.


drnick5

Thanks I'll give this a try. I was under the impression with the -lhr argument in nbminer you could only do -lhr 69 as a max. If you run LHR at 100 isn't that the same as not having LHR? (Which would mean you are somehow fully bypassing it?) I'd guess this is why your power consumption is jumping up and down as it's hitting the "wall" of the lockout


nice___bot

Nice!


JP8296

The LHR 69/70 apparently was the sweet spot to use the unlock. Yeah using lhr 100 is trying to full unlock the card, the card hits 118/120 mhs but then the software starts to reduce the LHR mode to 99 trying to prevent the card to lock but will settle at lhr 99 at ~ 110mhs


drnick5

Thanks. I just tried it, and after a min or so of mining at 118, it says LHR lock, then reduces it down into the 70's.


JohnMayerismydad

I guess I didn’t realize the 3080ti is locked. I get ~100 with my 3080


tyranicalteabagger

All 3060, 3070 ti, and 3080 ti are lhr. But don't have a special indicator that they are; because they always were lhr. 3060ti, 3070, and 3080 have 2 models. Earlier non-lhr models and new lhr models and large indicators on the box that they are lhr. Lhr isn't there to inhibit miners really. Nvidia is trying to screw everyone and pad their bottom line. They don't want a flood of cheap 2nd hand cards getting into the hands of gamers when this mining craze is over like last time. The 20 series had poor sales; because they weren't a significant upgrade or value and cheap 10 series cards were esay to get after the crypto market crashed.

So, I'm not keyed into the mining scene. Why are miners trying to use the gaming graphics cards? The workstation graphics cards are much more powerful, and have more memory (though more expensive). It's counterintuitive, but I use my rtx 3060 for machine learning most of the time, and it's actually really slow with Pytorch. This is because Pytorch uses almost all of the available video memory. On the computing cluster at my university, the same program runs over twice as fast on a tesla v100, and it has a cuda capability of 7 compared to the 8.6 of the rtx 3060. This is because the v100 cards in the computing cluster have 32gb of memory. So would workstation grade graphics cards be better for miners? Edit: so this is getting downvoted, so it would be great if people could clarify why I'm wrong 😅


tyranicalteabagger

Workstation graphics cards are obscenely over priced and always have been. You also don't need any of their special features or software to mine.


thelordmallard

Having checked a few mining calculators in the past, I recall that the hashrate (mining power) on gaming cards was highe than the workstation ones. Couldn’t explain why though, and can’t be bothered to check more. 😅


thenearblindassassin

I couldn't find anything specific on the rtx 3090 hashrate, but allegedly, the Tesla a100 can do 210MH/s which could give earnings up to 12 dollars per day. However, the A100 literally costs thousands of dollars... So I now understand why it's not used!


fizz306

Because you're never earn enough to pay back the cost of a tesla. The price comparisons aren't even similar.


thenearblindassassin

Ah I see! I suppose I was thinking of it like those people who invest crazy amounts into antminers for Litecoin and bitcoin, where the absurd upfront was mitigated over time. Like I said, I'm not well versed in ether mining, so I don't actually know how profitable you mining is


loiolaa

The upfront cost doesn't really matter, the metric observed is $ per mhs, and all enterprise gpus have terrible cost benefit, they cost more than double.


fizz306

To give you an idea my 3080 in my gaming rig earned on average about $5/day since January mining ETH when not in use by me.


Sobutie

What generation of cards do this? It is it a software thing? I didn’t realize this was a thing. I have a 280Ti and a 1080Ti mining in NiceHash.


BobisaMiner

It was such a sucky move by nvidia anyway. There are plenty of people who have ordered fully unlocked cards, only to be announced months after their order that their order has changed to LHR cards... F*** nvidia.
