T-rex miner specify GPU

Miners
1

Hi
I’m hoping someone is able to help me. I want to load one out of my 3 Nvidia cards with T-rex miner
I have tried --devices 5 and “devices”: “5” t-rex still tries to load all my Nvidia cards, any suggestions?

if you have 3 Nvidia GPUs in a rig then you can’t have GPU with number 5.
0,1,2 - this numbers of your GPUs for 3 GPUs in a rig

to load only GPU2 you need specify

"devices": "2"

I tried both --devices and “devices” with 2 instead of 5, t-rex still loads all of my nvidia gpus no matter what I put. I’m putting it in the flightsheet probably an issue with that. I’ve done it the same way with nbminer,gminer, phoenixminer, ect with no issues though. I’ve found a work around for now.

Any fix? or alternative solutions?

I was never able to get it to work. I just use gminer 2.64 now instead as it performs pretty much the same(actually slightly higher mh/s) has lower dev fees(on ethereum), and the specify gpu works.

hey guys,
here’s an example from my line code
t-rex.exe -a ethash -o stratum+tcp://eu1.ethermine.org:4444 -u
0x4be116d3f6d693d228231ce9879ff944939aaee1 -p x -w nemr --devices 1,2,3
i have 4 gpus and in this case im running 3, the gpu 0 isnt mining.

For t-rex goes like this (for one gpu):

“devices”: “x”

Or for more gpu’s:

“devices”: “x,a,z,q”

(The letters are the number of your gpu 0,1,2 etc)
