Title: Can't get 5GPU with Asus Prime z270-p (FIXED) Post by: Millime on January 16, 2018, 03:34:19 PM Hello !
I actually have a asus prime z270-p and I'm not able to make it work with 5 or + gpus. When I connect the fifth card, I see the Mobo logo but screen stays black after. I'm running on w10, this is my third asus prime z270-p and I didnt had any issues with the two others. The bios is updated to the latest version -4G enabled -Pci speed set to GEN 1 (tried with GEN2 but doesnt work) -Hd audio controller is turn off -Fast boot disabled Also, When i disconect the fifth card and reboot, w10 is showing correctly and the drivers are working My monitor is connected via the hdmi of the mobo. Thank you! EDIT: I've tried different pcie port and it doesnt make a difference, I can get 4 gpus working with any pcie port order used.

-What drivers are you using? -PCI Gen1 to all 3 points? -Power supply? I had the version H270 from asus and no problem with 5 or 6 cards.

disable the lightning port. double check the riser cable/swap the cable for another. try skipping a pcie lane with the riser.

(3 locations to change this) if you have done all this, than i think is a driver problem , try to uninstall and install fresh drivers , blockchain ati drivers,disable the lightning port. double check the riser cable/swap the cable for another. try skipping a pcie lane with the riser.

I had the version H270 from asus and no problem with 5 or 6 cards. -Tested individually, they all work -Risers/cables tested I had all 3 options set to GEN1, switched them to GEN2, switched them back to GEN1 and now it's working with 6 gpus.... Wow... What an annoying problem |
