Hey all, I managed to fix the RAM issue. Turns out it was a bent pin, possibly when it was shipped.
Now I'm having an insane time trying to get an NVMe drive to boot. On Windows 10, the drive shows up fine, everything works. I did the Beta BIOS update to 3.30P. Works fine. I did all the guides I could find, even using Rufus to make sure the USB was properly setup. But I can't find the NVMe drive on the boot menu. After hours and hours of trying this stuff, I don't know what else to do. One possibility is that my GPU is too old. It doesn't seem to have UEFI GOP. Thus it doesn't allow CSM to be disabled and Ultra Fast Boot to be an option. I'm not 100% sure if this would fix being able to boot from an NVMe drive though. Any thoughts?
