I have 2 powercolor dragon rx 470(4G) and 1 powercolor devil rx 470(4G).
I install step by step by this
But it can recognize my GPU
And clinfo does not show them
How should solve this problem?
thanks!!!
(lspci | grep)
I had at the beginning a problem like this one.
In my case it was not a big problem, but a long problem to find.
Short Version: If you use riser-card, check them ... check the USB-Connection and check the Risercards.
Do you try to install a Test-Windows-System (maybe on a second hdd) and find Windows your Cards? Windows had a lot lesser troubles with GPUs
BTW: On Ubuntu i like the small software "inxi" for hardwareinformations ...
"inxi -G" should show all GPUs
Thanks for you help!
Yes,I'm use riser-card, I would check them immediately.
But it is the problems of riser card's connection or just the riser?
I would try to install Test-Windows-System to check this problem, thanks for your information!
Haha, I has learn it, thanks!
I has some questions,before I added the third card(devil rx 470), they can run normally.
But after I added devil rx 470, it started have this problem.
And then I remove one of them (use only devil and dragon or two original dragon cards )
it could both work normally.......
I was puzzled by this.....
