    wait, which intel CPUs are we talking about? Your average Intel CPU doesn't have "per CPU memory"; it's not NUMA on that hardware level; multiple cores share the same memory controller. Or is this some rather old dual-socket server mainboard, considering the miniscule amount of RAM? Your specs are totally insufficiently detailed to help you! Commented May 16, 2023 at 8:09

    reserving physical memory addresses "per CPU" also makes no sense at all. This is really mysteriously nebolous – I think your question really only becomes answerable once you start describing 1. your actual hardware including mainboard, concrete CPU model & configuration, 2. explain what it is that you want to achieve by reserving that memory; what kind of addresses you're thinking you'll be dealing with. I think you might be abusing the term "physical address" here, but I'm really not sure, because this all seems so confusing and confused. Commented May 16, 2023 at 8:14
