Re: Any 32-bit Pentium based processor can address up to 64GB of memory We've been through this before, but your Alzheimers must be kicking in, again (still?). The performance hit for running all your hardware accesses through an external page controller is 50% up to 90%. A 32-bit machine, with 32-bit registers is limited to a physical address space of 4 gig minus what's been reserved by other hardware in the system. Beyond that, a kludge has to be added on that is essentially paging memory to a solid state disk. The trouble is, all your accesses are now going through hardware that treats the entire memory space as paged to disk, sapping bandwidth and horribly increasing latency.
