Hi again guys, im still struggling with my CPU upgrading, I was just wondering if this is true and wat it really means: Pentium 4 processors support 800, 533, or 400 MHz system bus speeds, as well as HT Technology1. The highest core speed is 3.40GHz So can i basically just buy any P4 and hope it will work on my 400mhz bus speed laptop?? i thought this mattered? Am i such a noob? Thanx

Doubt you can upgrade the Laptop CPU, it uses a P4-M, yes M for Mobile. Mobile CPU include speedstep to throttle back the CPU, if you put a Desktop P4 in there you would have one hot potato if it actually booted... http://www.intel.com/support/proces... So the rest of your post is irrelevent... Am i such a noob? Too polite to answer that one!!

... if one has to ask. Actually, it's the ones who profess 'expertise' that worry me In either case, status is easily determined, regardless (or despite) of whatever may be claimed I'm not one of those who think Bill Gates is the devil. I simply suspect that if Microsoft ever met up with the devil, it wouldn't need an interpreter.

thanx for reply, im using a P4 right now, no Mobile, 2.0 ghz 512 cache. it is a hot potatoe but i can live with it. so i was wondering if i can use a CPU with 533 or 800 bus speed in my 400 mhz 478 socket... that was all.
