I though XP could address 4 gig of ram?.
Admit to being a bit confused re 64 bit,the CPU in the Draper super puter is capable of 64 bit thingy,does it mean it will run stuff twice as fast?
Many moons ago I built a dual CPU pentium 500 on the understanding it would be swift,but only if progs had been specitically coded or what they called multi threaded or able to use two separate CPUs
