Issue Installing OSX onto x99 - Previously worked, Moved to Xeon 2690v3 no longer makes it through USB Boot to installer - PCI Configuration Begin.

So i have previously had mojave working on the following system:

Asus X99-Pro
5820K
RX580 - then later swapped out for a Vega FE
adata SX8200 NVME

It worked great then i had an incident trying to merge partitions, lost disk space and decided it was time to throw my xeon 2690v3 i had sitting around into it.

So i test my bootable usb with my 5820k, works fine. Swap the Xeon in and it takes a big dump at the pci configuration begin stage.

Now the only difference i can think of is that the pciroot address in the devices component of clover is wrong or it is having some hissy fit about the APPL,Ig-platform-id association is there with no IGPU.

Can anyone shed some light on this? Has anyone else used a Xeon with no Igpu?

I'd love to figure this out.
