Hello! I ran into a problem with my Msi Z270-A motherboard, so I am using 6 Asus dual 1070 OC graphics cards, and only 5 of them are being picked up. The second pci-e riser doesn't seem to be working. I tested the port, it does work and I have tested the riser cables, they all seem to be working. I am a little bit of a loss for words on what I should do to fix this problem.
What type of risers are you using, and how are they being powered?
Version 006 risers, with 2 risers plugged per port on my PSU using 6 pin to sata to molex, thanks for the help!
That sounds good for a riser setup.
First so we have a reference:
press f12 to open the guake terminal and enter the cmd:
lspci | grep VGA
and record what it outputs + before swap for reference
Then:
shutdown and fully power down (PSU as well + click the ATX powerswitch a few times to clear any remaining power in the system)
then swap the 2nd riser (riser + cable) with the 6th gpu riser + cable
power on and enter
lspci | grep VGA
and record what it outputs
then let me know what has been output each time.
Sorry for the delay!
Alright so something maybe worth mentioning, the boots seem to be taking significantly more time then before. (It's a problem I should be able to figure out once the GPU's are all running,
So the initial test returned:
1:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
3:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
6:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
7:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
8:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
9:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
I was waiting for a solid 15 minutes for it to boot, and it wasn't so I used a different USB to boot since I believe the first USB might have been corrupted from all the restarts.
After here is what I got:
1:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
3:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
6:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)

8:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
9:00.0 VGA compatible controller: Nvidia Corporation Device 1b81 (rev a1)
