Just FYI, you get a lot better performance from the sytem with the higher FSB if you have two systems running at the same total speed. FSB is the FIRST thing you overclock, generally. Then once you hit your max, you start increasing your speed using the CPU multipliers (multiplier x FSB = total speed) and find the happiest speed with the highest FSB you can obtain.
Whoever told you faster memory would clock tighter if you just ran it lower wasn't giving the best advice. Yes, it WILL generally run tighter the slower you go, but you'd be better of paying for ram with a lower speed rating and tighter timings upfront than spending a similar amount for a higher-speed rated ram that's rated for slower timings, as there's no guarantee it will run tighter timings if you try and slow it down.
Look at some G.Skills (newer ones with the Winbond chips on them ... don't remember which line they are; sure someone else here could probably remember off the top of their head), OCZ VX or VX Value, or the Twinmos in the PC3200 range. Or wait a week or so and give the new Mushkin Reds a try (Diane at Mushkin said she expected them out in about a week).
They all have some headroom to go higher than 200Mhz when you start overclocking, and all of them have pretty tight timings already at PC3200 speeds, which you can tighten even more when you give it voltage, especially with the OCZ VX and the Mushkin Reds (though unless you like to be a person to test stuff out first, I'd hold off on the Mushkin for a bit until others test 'em out).
Love to see a link to a "0" timing, because I've never seen that in my life. Seems mathematically impossible, but I'm not one to knock something till I've seen it. Getting 1.5-2-2 is about the best you'll ever hope for, but on an Athlon XP system, expect 2-2-2 to be a realistically obtainable "best" goal with the right ram.
