Yeah, you got it Well like, my motherboard, socket A, is only capable of 400FSB max, so I of course need to have a 400FSB CPU ( I know you know this stuff just follow along a little more ) and of course some PC3200 DDR400 RAM...now that thats taken care of...I'll start raising the CPU FSB from 200 and go on up.
Really unless you are overclocking the RAM though meaning keeping the CPU:RAM at a 1:1 ratio then its pointless to overclock the CPU FSB past 200 if your RAM will simply bottleneck it.
Anyway, you generally won't need to raise your NB voltage until you start getting to like 220 - 440FSB and then you'll probably have to raise it a knotch.
With the RAM I'm getting it's rated by the company at DDR400 = 2-2-2-5 timings or DDR533 at 3-4-4-8 timings, of course most reviews I've seen the RAM hit DDR533 with even tighter timings, but the company GUARANTEES it to run at DDR533 with 3-4-4-8 although it may go tighter.
I'm hoping to hit 240MHz or a total system fsb of 480 which will require probably 1.8-1.9 NB Voltage and stock voltage is 1.6
The stock NB cooler is never enough though. That's why I'm getting this:

4W4K3 showed me of that little beauty. MOSFET and PLL chips to cover ALL the voltage regulation chips for maximum heat dissipation
