Nevermind, I am blind.
Got it working with 16GB RAM. Could not take it to 24GB. Any thoughts?

@dcarrion87 probably some address space limitation, dmesg should say why.
you're lucky 16GB RAM works because for others only 8GB worked
System
Description
I have a similar issue to https://github.com/xCuri0/ReBarUEFI/issues/77.
CSM is disabled, Memory Remapping disabled. I've tried memory remapping enabled and nvidia-smi doesn't work with no device found and dmesg showing IO region errors.
I think I only need to do the DSDT patch?
Currently running with 8GB RAM trying to get a 24GB P40 working on Ubuntu 22.04
I followed the DSDT patching guide https://github.com/xCuri0/ReBarUEFI/wiki/Sandy-and-Ivy-Bridge-32GB-BAR-DSDT-modification but can't even get it to compile at the moment. The error lines don't match up.
Just wondering if someone could point me in the right direction so I can diff the files to see where I'm going wrong. The original output files:
errors.log.txt
dsdt.dsl.txt
dsdt.dat.txt
