    ok.. so it does sound like if I get a 800MHz FSB processor that It will resolve the issue with the memory?? And if so... will it add to performance... I mean.. right now where it is seeing it as 2100... is it running slower then it would if it was reading it at what it is?? 2700??

    i'm not sure bout that

    but it should be running @ PC2100 / DDR266 speed..

    P4 400mhz system bus .. a dual channel PC2100 would work like a 266x2 = 533mhz .. which is more than your processor..

    p4 533mhz - PC2700 will run @ 2100 speed
    dual channel (266x2=533mhz)

    p4 800mhz - PC2700 will run @ 2700 speed
    dual channel (333x2=666mhz)
    you'll have a lil bottle neck there
    but it should matter much i guess..
    Max_87 should know more bout this

    I have another question... is it good to make your cpu run faster?? Like I read last night that you can change the multiplication factor... like mine is 100 x 4=400
    it said you could change the 4 to a 5 or something like that...
    Like you could make a 400MHz run at 533MHz... Is this a bad thing to do? Let me know what you think.

    :shock: i just realised i did a big mistake
    sorry for the wrong information

    p4 400mhz - RAM will run up to PC2100 speed
    p4 533mhz - RAM will run up to PC2700 speed
    p4 800mhz - RAM will run up to PC3200 speed

    but it still depends on the motherboard..
    getting either a 533 / 800mhz system bus processor will make you RAM run @ its max.. (in your case PC2700)

    but you cant change the multiplication factor... (multipliers)
    100 x 4 = 400
    you cant change it to 100 x 5 = 500
    4 - quadpumped.. its the processor itself..

    i think you meant by 133 x 4 = 533
    133<-- front side bus

    thats considered overclocking 8)
    Pentium 4 can overclock pretty well ..

    well .. i cant say its bad :mrgreen:
    like mine .. 800mhz system bus running @ 960mhz system bus
    i'm not the o/c guru here..
    but overclocking too high will result in unstable system or shorter processor life...
