I have an HP pavilion 6830. And on the HP website when I checked out the stats for my PC's processor, it told me that it was an Intel Celeron processor 700 MHZ, it has socket 370and that the front side bus is 66 Mhz and that it is upgradable to 800Mhz. Like, am I suppose to look for a ram that has the same number socket and front side bus # or can I get any Intel Celeron processor as long as it's 800 MHZ? I'm real confused here as to what to look for when purchasing a new processor. In addition, is it possible that you can use a processor from a labtop on a desktop PC if you wanted to?
