I have a First International Computers AM37 motherboard and I was wanting to put in a new CPU. I know I should just get a new mobo but I want to get a new CPU for now.... But anyway, on the FIC website, it says my mobo is compatible with an AthlonXP 2400+ and a 2600+, why did it skip 2500+? The website doesn't list the 2500+ as being compatible but why would it be compatible with a newer CPU than an older one? Is the 2600+ an ok overclocker, or 2400+? Not for big time overclocking, just like 200-300mhz(I guess thats not too big...).
The 2400+ and original 2600+ used a 133MHz FSB (266MHz DDR). The 2500+ and newer 2600+ uses a 166MHz FSB (333MHz DDR). So they're refering to the older 2600+ with the slower bus speed, I doubt your board supports the faster bus speed.

Is it faster to run at higher FSB, and lower multiplier or lower FSB and higher multiplier? Or does it matter? I just got a new heatsink which is supposed to be able to handle up to 3200+, will that keep a overclocked XP-M 2500+ at lower temps(Say around 40-45c)?
At the same speed, a 133 chip gives up a few % to a 166 chip. A chip with a fsb of 133 and a total speed of 2.527 would perform as well as a 166 chip somewhere around 2.45.
If your board will run at 166 fsb, use that, if not, 133 will pretty much get the job done. Either of the two speeds suggested are a very high oc for the xp-m chips. I find 2.4 is adequate, many stop at 2.2.
I just checked the manual, and couldn't find a place to change the multiplier. I have heard of software that allows changes in windows, but the one I kinda know is for Gigabyte boards. Oh well, the xp2400+ is still a pretty good chip.
2400+ is a solid choice, but I think he already has a 2000+ in an Emachines' system. I don't think a 2400+ would be a justified upgrade. IMO, his best bet would be to get a cheap NF2 mobo, ATX Case/PSU, and a new HSF; and hope that his current CPU is a Tbred-b that'll be unlocked past 12.5x multis. At least that's what I'd do :wink: .
