Originally I had 32GB RAM when I installed XCP-NG
Now that I added 2 additional sticks to the system, the OS doesn't pick it up.
dmidecode sees those sticks. If I disable SR-IOV, the RAM is usable.
But I need to pass a PCI-e card to a VM so I can't run it disabled.
On XCP-ng 8.2.1 currently. With Legacy boot.
Any ideas how to fix it? I even tried to tape the card Pin 5 and 6 on the Raid card, but there's no difference.
Is it just limitation of the Motherboard? Or the CPU itself? I rmember early Ryzen days Ryzen had memory issues.
Or a Hardware bug?
