I managed to pick up a 3070Ti for basically just the shipping costs and I've been trying my best to figure out how I'm supposed to interpret the TBMiner output for tuning. The following screen shows some very confusing information and I'm wondering if there's something wrong with the setup or if this is what I should expect with LHR cards:
In my tests, the autotune can reset a few times and still give a good result. With your current settings, 48MHASH should be the expected speed. Abit low but stable. Adding more LHR cards to the rig or normal cards can add stability and speed to the unlock.
A freshly rebooted rig with the miner running in a startup script seems to be performing best. use --log.
The debug output from the LHR code can be removed with a setting --no-verbose , work is still in progress.
This LHR business is weird... I created a startup - no login script to run the miner on my windows machine (so none of the other user-level garbage is loaded on login), and I set the
--LHR-unlock to "0" with a --tweak of "5", to test the baseline full LHR speed (what Nvidia intended for the card to do when mining ethereum), and
over the past 16 hours the miner share rate has averaged 54 MH/s and
2Miners poolside for the past 6 hours is 61 MH/s ...
Which is better than the
47 MH/s I wound up getting when logged in and running an LHR-unlock of -25 / tweak 2 (which was required to allow the miner to mine for > 300 seconds without a reset)...
Based on the non-LHR architecture with GDDR6x RAM, I would expect that the full non-LHR hashrate of this card under a standard miner without insane OC's would be between 67-69 MH/s and getting and average of 54 MH/s
without unlocking means it's running between 77 - 80% of its maximum potential at baseline... Is this normal? Am I missing something about how the
--LHR-unlock 0 functions? Are my current OC values pushing the card beyond the 'normal' LHR and the standard TBMiner advantage is just compensating for the cards natural speed lock?
