help with Athlon XP

[petebert]

just got my Asus nforce2 board today, still looking for a cpu, the manual says it supports XP 2800+ or higher, AMD's site says it supports alot starting as low as 1700 I think. Whats the deal with the FSB? dont the 2100/2200 run at 133? why's this Asus board say it supports 200/266/333? is cpu 133 really 266 on the board? I was digging around on AMD's site(which I found very little on) and they had a version 6 and 8 for like every cpu, whats the difference? anything to do with the A or B, which from the little Ive read on message boards the B is apparantly better, how do I know if Im getting a 6,8, A or B? I might just end up going to the local computer store so Ill be able to actually hold it and look at it first. I was thinking of going with the 2100+ retail before but those are now apparantly non existent, store up the road has em OEM for around $104 warrantied for a year. any good reasons why I should consider going faster then the 2100+? the 2100 seems to fit my budget nicely, the next step up to the 2200 is a pretty decent difference.

What AMD calls a 266MHz FSB runs at 133MHz. 333 at 166 also. So what you're seeing are marketing numbers and real clock speeds being mixed together in an array of confusion. Not to worry as all the stuff works

I got one of those boards too a few weeks back and put an 1800+ in it (all I could afford for now). It flies
I found the BIOS confusing on this board tho....RAM was set to 200Mhz, other choices seemed to be 133Mhz (which I'm now using) and 166Mhz. Seems a bit inconsistent!
I think the B's run at 166Mhz (333) and the A's at 133Mhz (266)

I would like to know if "A" stands for 266 FSB and "B" stands for 333 FSB. Also, does "B" means that the cpu is using 0.13 micro tech?
Any info is appreciated.

A and B are different thoroughbred core revisions. They are both built on the .13u process AFAIK however the A was just a slight improvement from the palomino yet the B was completely different. The core has nothing to do with FSB, only Processors of 2600+ or above have the 166FSB (333) and there are some A's and B's that run at 133FSB(266). So no, A and B dont stand for anything in terms of clockspeed.
