Memory Address Limit for proxmox

Hi Everyone,
Is there any information about Memory Address Limit for proxmox?
VMware has it described below.

I am having issue trying to pass through 8x Tesla GPUs to a VM on ovmf bios and suspecting could be related to settings in BIOS.
All 8 GPUs can be listed under lspci but memory could not be allocated to BAR.

Any suggestion is appreciated. Thanks.
Some updates.

Apparently I have better luck with SeaBIOS, managed to get 8 gpus passthrough correctly on a 256GB RAM VM.
Correctly as in nvidia-smi showing all the gpus.

Unfortunately I have issue if I set the VM's RAM higher ( => 512GB)

Will share here if I find out more.
