I know this is an old issue but one of my rigs is throwing blInitialLibrary failed error on boot up only when I have 5th gpu connected. It works fine with 4

My setup:

Asus Prime Z390-P

8 AMD 580RX GPUs

2 EVGA 750 G2 PSUs connected together

Windows 10 Pro 64 bit

BIOS has been updated to the latest

4G Encoding is enabled

I tried both Gen 1 and Gen 2 and still get the same error

Secure Boot Disabled

Fast Boot Disabled

I have tested multiple combos of risers to PCI slots. All risers and GPUs are working fine individually but on the 5th one, I get the error

I am lost and could use some help

thanks

EDIT/SOLVED: I had to go to ASUS website get their beta version of the new bios.  After install things are working ok now

I found the thread.. thanks

Has anyone seen this?  What do we make of this?
