NBMiner Update Restores up to 70% Mining Performance of NVIDIA LHR GPUs

btarunr · Aug 16, 2021

The latest version of NBMiner, a software that helps you mine Ethereum, purportedly restores up to 70% of the mining performance of NVIDIA GeForce RTX 30-series GPUs with LHR (lite hash-rate). The latest batches of the company's GeForce RTX 3080, RTX 3070, RTX 3060 Ti, and RTX 3060, are LHR by default, meaning that the GPUs feature a mining hash-rate limiter that throttles the GPU when faced with workloads resembling mining; with the idea being that they become unviable for miners.

The latest NBMiner update doesn't completely restore mining performance for LHR, but works around the LHR restrictions. The ETH mining hashrate is increased from 50% to 68-70%, which is a definite improvement. This is also the first public miner with improvements made to LHR GPU mining performance. Until now, only private mining groups have claimed to develop custom miners with workarounds for LHR GPUs.

Must be some kind of heuristics going on. Otherwise why not limit it to 10%? That would more then deter miners even with the ability to boost it 20%.

It must affect other types of workloads?

Correcting the article, lolminer was the first with 3060.

they can limit it to 0 if they want its easily hackable always was with just removing and replacing a few resistors they are screwing gamers the same way selling them a nerfed $800 dollar card that can run the exact same as $1400 card with the same mem

also i think techpowerup is in cahoots with nividia im curious how nvflash works one day with my 3070 then all this lhr comes out then cert bypass wont work with the card anymore same bios same card !

watzupken · Aug 16, 2021

I feel it is a matter of time before the hash limiter gets circumvented. This is especially so when there is financial incentive and people actively trying.

Chrispy_ · Aug 16, 2021

LHR cards haven't curbed mining in the slightest anyway; On the discord server for my mining pool everyone who ends up with an LHR card just mines Ravencoin or ERG instead.

Tsukiyomi91 · Aug 16, 2021

knew that LHR cards would get circumvented. Not surprised.

all that money that they make....and they cant prevent somthing like this? come on Big N

Good thing most good games are indie games these days and all pixel art. So when my 1070 dies i can just use my iGPU.

Even if the LHR lock wasn't circumvented, it's irrelevant by the end of the year because the only crypto it prevents you from mining effectively is ETH and ETH's mining days are numbered anyway. Rumours point towards ETH mining being effectively "turned off, permanently" by the end of the year so an entire planet of crypto miners already have alternative strategies in place that don't care about Nvidia's LHR locks.

yeah so easy to remove and replace resistors lol, come on...

and lhr is new hw, that is supposed to defeat mining, so its not a surprise they would introduce new locks on the bios.

Explain it away then or you where paid to change it quietly behind closed doors and dll files dont do squat if you cant use them where are all the 2216 bios files none of them listed but a user posted one so explain how a few months ago i could use cert bypass downloaded from here on my 3070 changed the bios just fine to another bios and could change it back the same bios is on my card now but cert bypass no longer finds the card but the new nvflash sure does you cant !

and this isnt the only site Nividia went through Google had other sites remove information or the site deleted entirely

yeah buddy a few resistors they are all around the bios its as easy as changing the hardware id from 2216 to 2206 and running a 2206 bios and different driver ! its called a hardware strap or hard strap its what nividia uses to decide what card they want you to own in that memory line nothing else what driver it uses what bios it can load what the driver does is all controlled by what can be loaded to that hardware id

I love how the only punctuation you used in that blob is an exclamation point.

You need to clarify wtf the issue is, because that sentence makes no sense.

go look at a lhr card how they yanked the second bios out of the card the switch and all the resistors that control the hard strap they did so if you mess with the only bios on that card and dont know what you are doing it bricks if i didnt know what i was doing i would be sitting here with a bricked card

No you said you can defeat the anti mining measures by "just removing and replacing a few resistors". Maybe there's a language barrier, but I take that to mean you physically removed something from the card, not just in software.

So you are saying just flashing a new bios, you can beat the new LHR measures? Are you saying your 3070 is an LHR?

95Viper · Aug 16, 2021

Stay on topic.
Stop the trolling, thread crapping, and bickering.
Stop insulting other members.
Have a civil and technical discussion.

Thank you and Have a Good Day.

i have 2 different cards 2 different problems 1 i didnt care to mention again its my 3070 and its with nvflash certs bypassed not seeing my card anymore thats not a big deal it works and is maxed i dont care i have a 3080 lhr card there is only one bios on this site that techpower has its user posted not trust it works but thats the only one thats the only problem with techpower i have then people are asking about hard strapping so its 3 different convos getting mixed together im not used to fourms sorry

and no you will not defeat 100% of the lhr without knowing the resistance to change it from 2216 to 2206 removing a resistor and replacing it with a different value

i also feel nvflash picks up more then people think the 8mb memory bios has a one time area that can only be written to one time and i think it loos at whate bios chip numer you are using but doesnt matter no software hacks needed after it recognizes it as 2206 instead of 2216

this hardware hack don't mean squat now that 70% is unlocked at least not to me anymore been working on software for a month im sick of typing 0000000's

You are correct on hard strapping. You are not correct on the files changing. I keep a mirrored archive of the cert bypass versions in case such a thing were to happen. As it happens, hashes still match. Nothing has been changed except perhaps a new version being posted (have you tried older?). So I'd quit peddling a conspiracy that isn't true.

What's the state of the card? What model? PM me if you are interested. I may be able to help, or even willing to buy said card.

it was a older version one of the 2 in the middle yes i tried ive been in front of this computer for 20 hours a day for over 30 days and i know nvflash i stripped it all the way down to 5mb from 10 and still had it working
