So I came up with a solution to this using MSI Afterburner. Not as easy as making the lights flash but it does work.
- Un synch the cards.
- One by one, change the fan speed to 100% on each card so you can identify the one in question.
Keep in mind EWBF starts at GPU0 which actually equals GPU 1 in Afterburners
EWBF GPU0 = MSI GPU 1
EWBF GPU1 = MSI GPU 2
EWBF GPU2 = MSI GPU 3
and so on.
I did as well find I can set the ID of my GPU’s based on how they are connected to the motherboard. At least this does work for my z270-a. Others will have to test themselves.
PCIEx16-1 = GPU 0
PCIEx16_2 = GPU 1
PCIEx16_3 = GPU 2
PCIEx1_1 = GPU 3
PCIEx1_2 = GPU 4
So in review it ID’s the x16 slots first in order and then the x1 slots in order.
Hope that helps somebody else.
Now just need to figure out why this rig keeps freezing.
