NBMiner update unlocks up to 70% of NVIDIA RTX 30 LHR series mining

@renelacerda it works but it’s power hungry

Does anyone knows how to setup the LHR limit of nbminer in hiveos?

Use nbminer not phoenix

Just do nothing :slight_smile:

Auto unlock just works.

It worked, but I’m only getting 32 MH/s. I can get 36 MH/s using lolminer. What OC are you setup?

lolminer gives 75% of full hashrate, try nbminer with “lhr”: “75” setting

After using nvidia-driver-update to get to 470.63.01, didn’t even have to add any arguments (it just saw that the 3070ti was lhr and defaulted to “lhr”: “68”). 3070ti Asus ROG Strix went from 44.53MH at 140W to 54MH at 173W.

For those having an issue putting the extra arguments into HiveOS flight sheet like I did, the config would always fail and got fatal argument error, you use:
"-lhr": "68"

  • you need the dash at the beginning
  • you need the space after the colon

so is it awesome? hell ya.
do you switch from RVN to ETH for max profitability?
…no, not my cards. RVN is still over twice as profitable, but hey, this is a great step, and some people don’t mind less profitability and instead want more ETH, so this will help them even on LHR cards.

hope that helps.

edit: also, I couldn’t get it to use a different lhr number…no matter what I put, it always says in the logs that lhr using mode 68…even if I do “-lhr”: “-1,-1,-1,etc etc” on the cards in questions, it still uses 68…hmmmm

On Trex works better for me… same setting on Afterburner different results.

Nvidia driver: 471.68

Does this only work on the ti cards?

I was able to get the lhr command to work, I used “-lhr”: “70” at first, but noticed it didn’t make any changes on the miner log. But removing the - and using “lhr”: “70” worked and the log reflected it after the miner restarted. Hope this works for others.

edit: 70 value caused the unlock to not work and hashrate went back down to lhr hashrates. 69 worked for me and kept the unlocked hashrate. YMMV

For me it works on Rtx 3080 Aorus extreme 2.0. Before update i was getting 54mh/s, and now i get 67-69mh/s. Can’t wait for another update :slight_smile:

I think nothing was unlocked, but the miner was tuning out the protocol… either way, this is good for us, thanks to the developers…

I have the same GPU but it didn’t work for me, can you share your stats?

“lhr”: “68” (tried also 70 and 75)
OC: core: -500 | mem: 2000 | power: 230 → 54 MHs
Drivers: 460.91.03

I just had to update to Nvidia drivers, works great now +65 MH/s :slightly_smiling_face:

I have this line in tunings extra config arguments: “lhr”: “69”
And these are my gpu settings:
core: 1090
mem: 2500
PL: 240
Drivers 470

I got 57-59 with the same stats.
Not as good as you but it’s an improvement… thanks!

Do you have latest nvidia drivers installed?

Yes, the latest available in hiveos (470.63.01).
I’ve also upgrade hive to 0.6-209@210822 but with modes 68,69,70 after 10 minutes the MHs drops to 38.
