T-Rex 0.25.12 for LHR Cards (Win10)

Post by -MaVerick- » Thu Apr 21, 2022 12:05 pm

Hello fellow miners,

you might have caught a glimpse of my enthusiasm in the shoutbox, T-Rex is the mining software to go with right now when you got Nvidias LHR cards. Usually Gminer was my GoTo Software, but because of some reports about T-Rex and, to be honest, I currently don't really like transfering money to a certain country, I gave it a try. To make it short: Its great. Use it. Really!

If you already got your feet wet with command line configurations, it shouldn't be too hard to switch to. Here are my 3060ti lines for Gminer and T-Rex, using driver 512.15 and Win10:

Gminer
miner.exe --algo ethash --lhr_mode 1 --lhr_autotune 1 --lock_cclock 1350 --mclock 750 --tfan 55 --tfan_min 60 --server prohashing.com:3339 --user x--pass a=ethash,n=GPU3060ti,o=1

T-Rex
t-rex.exe -a ethash --lhr-autotune-mode full --fan t:55[60-100] --lock-cclock 1350 --mclock 750 -o prohashing.com:3339 -u x -p a=ethash,n=GPU3060ti,o=1

Locked Core at 1350 with +750 on memory, a target temperature of 55°C and fan speed between 60-100%. Gminer usually managed to unlock up to 74%, about 42MH/s. T-Rex is at a whooping 79,4% with up to 48MH/s depending on how active I am on said PC. Speaking of which, Gminer ran into locks quite frequently when the PC was in use and lowering the unlock %. T-Rex is rock solid at those 79,4% for 2 days, 14 hours and 13 minutes right now, triggering a lock maybe every 10-12 hours, if at all, no matter what I do. I don't know what kind of magic is at work here, but I love it.

According to the ReadMe you better turn off any displays/disconnect any remote sessions connected to the mining maschine while it does its calibrations for the unlock 1-2 minutes after start. That's what I did with my 3060ti and it works nicely. My wife with the 3060v2 on the other hand had both displays active today, playing WoW and reaching 87,8% unlock, with T-Rex being in low power mode. I don't have any explanation for that, so...yeah. It just works.

:)

Are you running the fix for the first beta?.... if so I believe you were to remove the lhr auto tune and let the fix decide.... I had the same symptoms as you and this corrected that plus went to 80.4 on 1 card 79.8 on others.

"--lhr-tune" and this autotune commands are different. Tune is for the starting percentage, which gets calibrated in the first few min. Autotune is for adjusting the unlock percentage while running. As I am using this PC quite regulary, I thought there would be more adjustments because of activating locks. But thats a big nope so far, solid as a rock.

This is what I'm referring to...."Also, don't specify --lhr-tune or --lhr-autotune-mode, and let the miner pick the tuning values on its own"...from their Discord page

Oh I see, I though it would only relate to "tune", not "autotune", as stated here -> https://github.com/trexminer/T-Rex/releases
I'll give it a try later, also gonna test out some games. Maybe it likes other RPGs even more? :D

Edit: they also forgot to delete those commands out of the ReadMe.

ReadMe Example:
--lock-cclock 1000 (applies clock 1000Mhz to all cards that support this functionality)
--lock-cclock 1000,1300,0 (applies clock 1000Mhz to GPU #0, 1300MHz to GPU #1, ignore GPU #2)

So it would be --lock-cclock 1350,1350,1350,0 --mlock 750,750,750,0

This is how my command line on the 2 1060 6GB looks like:

t-rex.exe -a ethash --pl 70,70 --fan t:67[60-100],t:60[60-100] --cclock 180,180 --mclock 550,550 -o prohashing.com:3339 -u x -p a=ethash,n=GPU1060s,o=Sklave

"Hey honey, you said this LHR number is important, right?"
