Hey!
Thanks for your reply! I ended up actually coming to a fix literally 20 minutes before I saw this post. Now that all 6 are properly working I'm planning on overclocking the GPUs for better hash rate.
However, in bios I set them up as GEN1. Should I change to GEN3 if it's already working under GEN1?
So, those MSI motherboards are bitchy little units. I have 12 rigs using MSI Z270-A and the initial setup is a bit of fiddly crap to make work.
What we do here is.
- Boot with USB cables removed from cards. Risers can be plugged in.
- Upgrade board firmware
- Install OS
- Install drivers for onboard video
- Go back to bios, enable over 3g video setting
- Enable integrated graphics as primary video
- Change PCI risers to GEN3
- Shut down machine.
- Connect 1 video card
- Boot to windows and verify it shows up
- Shut down and reconnect all risers.
- Power back up.
- Enter bios and verify board explorer shows all PCI slots full
- Boot to windows
- Install drivers
- Profit
I hope that helps. They sometimes work in GEN1, but GEN3 seems to give the most consistent results.
