Does anyone know if Virtual PC was written to utilize dual processing technology? Does anyone have any experience with Virtual PC on a Cube with a stock processor and/or an upgraded version? Is there any known advantage to trying putting RAM into the Cube homogeneously, i.e., purchased from the same vendor at or around the same time or is it just a matter of having working RAM? At a minimum, there are probably some aesthetics reasons to try to purchase RAM in the same increment(s), at the same time, from the same vendor. I know in certain audio/video operations there are reports of problems if you do otherwise. Thanks, Dave Iverson
