I'm planning to set up a dual Linux OS desktop using Fedora 42 and Ubuntu 24.04 LTS. Right now, I've got Fedora 42 installed, and I'm about to add a second 2TB NVME m.2 SSD for Ubuntu. My setup includes 64GB DDR5 RAM (2x32GB sticks running at 6000 MT/s) on an Asus Z890 ProArt Creator WiFi motherboard. I'm considering whether it makes sense to upgrade to 128GB of DDR5 and split it equally between the two OSes in BIOS. Alternatively, should I just run both systems with the existing 64GB? Are there performance benefits to either setup, and what's the best way to configure this? Cost isn't a factor for me.

Are you looking to dual boot or create a hypervisor to run both OSes simultaneously? If you're dual booting, keep in mind that whichever OS you boot will use the entire RAM available, not split it. However, if you opt for a hypervisor setup, you'll want to allocate some RAM to the host OS and configure the VMs to use a bit less than half of your total RAM. Just remember to leave some memory for the host!
I'm going with the dual boot setup, so how should I configure the RAM for that?
