Alright, y'all I'm a security researcher and I've spent around thirty hours researching this topic because I see the value in it. Here's how far I've gotten to date: NVIDIA claims there is only one way this could be done: a custom-made BIOS. The security enforcing the LHR limit is implemented within both the BIOS and the GPU directly using an NVIDIA-developed security feature called Falcon. It implements the following security features:
Essentially this means it is locked down TIGHT, however not all hope is lost. After spit-balling about it for hours with an undergraduate student named Nathaniel Huggins at Liberty University who should probably be running Intel's engineering department, I would like to suggest the following methods that could succeed, (albeit with a lot of effort.)

It's kind of old, but try injecting TPM commands on the I²C bus? https://www.sciencedirect.com/science/article/pii/S0898122112004634

I was interested in this article until the author mentioned Liberty University. I then noted in his bio that he is Christian. This is likely all psuedo intellectual babble. Ignore it.

So by your logic, all Christians are morons and should never be allowed to have input on technical discussions. Got it.

No mention of the miniZ LHR unlock, I am unsure of 3060ti but on all the LHR V.2 3060's I have I can get hash rate to 39-42 stable at pool holding for days and days on end. With the max hash of not lock being 46-49 MH/s I think you have over complicated a not so complicated issue here. The lock has to do with power and how much of it is so allowed to flux through the core, and Vram . That said and my listed stable 24/7 on ETH mining there are windows of 2-4 hours it goes to 44-46MH at pool and in miner which in miner is pointless what the pool detects is what I am getting after so calculating reward for weeks on end each day.anything out of the window of 99-101 watts and all is GONEEEEE keep it in that window and you are good. works better on windows in pure irony, wow never thought I would have that in a run on sentence for the rest of my forsaken life on this rock. also over clocks will alter that pull of power, CORE and Vram must be adjusted accordingly. for 3060 LHR V2 that is windows core clock MSI after burner -145- -152. Vram 1348-1352 power limit 58-60% double the core and vram clocks for linux of course but anyone reading this here probably already knew that, I have played with it and gotten almost full has rate with platinum PSU ONLY and in windows only but hash would not remain at pool stable beyond the 1 hour 30 min mark.... there you go, coders, hackers and freaks of nature like me who dream in binary lol commence this old timer ex hacker is in to much pain and to tired to play with this crap any more, but you young bucks are better than I and this is not some trolling. FUCK Nvidia for this crime and theft to which they sell the first batch or 2 before vendors list card are damaged on purpose at factory no screw that shit, not okay, even if not a miner the reward will be the fame and knowing you alone did what all before so failed to do. For the most complex of problems the most simple of answers is the answer. Given Nvidia I do not see them using the man hours or money to do a complex engineering master piece of complexity. MINE ON, HACK ON!!!!!

Your comment is full of ignorance and with the ignorance comes the prejudged: all the biggest scientist that we have had as human kind believed in GOD, as Isaac Newton, Nikola Tesla, just to mention a few.

In year 2022 the LHR You can unlock easy just use the removeLHR @com and your GPU is NON LHR

Nvidia was recently breached and the source code for the firmware is rumored to have been leaked. Others are claiming this is a scam. time will tell.

That website looks as suspicious as it gets. No source code, no content, just a single page with a suspicious pile of mirror download links.

if they give the source code then nvidia is going to change the lock. Like that is always. Leave a Reply. |
