Hello,
I've managed to run 4 graphic cards so far with this setup.
- Motherboard: Asus Prime Z270-p
- 4 x GTX 1060 3G (ultimately need to install 6)
- RAM: 8 GB
- Intel pentium 1151
- Cards are connected via powered risers
Relevant software
- Ubunutu 17.04
- Latest Nvidia binary driver 281
I know that installing 4+ cards is usually problematic in Linux. I've been following the instructions in https://bitcointalk.org/index.php?topic=1917749.0 and they helped me install 4th card. However, the instructions are extremely indeterministic and don't have a clear order. They usually involve:
- Turn on/off Bios "Above 4G decoding".
- Change PCIE link speed to Gen 1, 2 or 3.
- Change DMI Max Link Speed to Gen1, 2, or 3.
- Add one card at a time.
Once I install 5th card into motherboard and turn on computer, I get one of the following issues:
- Ubuntu boots fine but "nvidia-settings" only shows 4 cards
- BIOS splash appears but black screen afterwards
- No BIOS splash appears. I just get the error:
Error: unknown filesystem.
grub rescue>
I realize I'm completely lost and can't make sense of what I'm seeing. But that's why I'm here! I'd really appreciate any debugging tips.
Thank you
