       Yes, I would think that you would notice a big difference. If
before adjusting you had a 66.8mhz fsb x 3.5 multiplier = 233.8mhz and
after you have a 66.8mhz fsb x 8.0 = 566mhz. You might want to check and
see if you have a fan on your cpu (I have a 566mhz that doesn't), if not
and you do notice instability adding one would probably fix it. Also if
you dont have a fan now, adding one for $10 is a cheap way to overclock
it. I'm wondering though, where does the 100mhz fsb you mentioned come
in? You will either have a 66.8mhz fsb times a multiplier or a 100mhz
fsb times a multiplier
        As far as memory goes, I think most people that read this list
would agree that you can never have to much. When you run out of
physical ram and have to swap to disk it slows the machine waaayy down
(and causes dropouts).
