two GRID K2s in Cisco UCS C240 M3

Getting splats on 3 out of 4 display adapters in device manager stating "This device cannot find enough free resources that it can use. (Code 12)". Anyone have a fix for this? Cards are in slots 2 and 5 and the server BIOS is 1.5.4.

I am testing two K1 cards, that seems to work fine for me.

Can you give a little more detail on what you’ve installed and how? i.e.

OS versions & it’s config e.g. are you running Windows Server 2012 R2 Hyper-V
Bare Metal or Virtual
BIOS configuration for PCIe
Driver version & source link
