Motherboard questions for Tbred/Barton, 266/333FSB support

I'm a little confused.
When (AMD) mobo mfg's list their supporting CPU's, they list Athlon, Athlon XP, and Duron. They don't say whether or not it supports Barton, or just Tbird & Tbred. So if they list supporting 333FSB, does that always mean it suports Barton?
Example, I was looking at Epox Nforce2 boards, which say 333FSB. I was also wondering if my Epox 8KHA+ 266A board supports Barton, which the mfg specs say it supports up to 266FSB, an Epox tech on another forum (overclockers.com I think) said it officially does not (though I think a couple people on here and OC forums are running w/ one). Though I don't know if it not being officially supported is just because it's 333FSB.

Slightly on topic, is the fastest Tbred a 2600+? There seems to be a 266FSB and a 333FSB version (Tbred), but I can only find the 333FSB for sale (and again I dont know if it would officially work on the 8KHA+ or not). Also This mentions a 3000+ Tbred, and says it's a 333FSB chip. Did this never make it to production?

Is there not a 2500+ Tbred?


Is there a good chart somewhere showing all of AMD's chips and details?
 
Ok, easy ones first:

  • All 2500+ are Barton core
  • All Barton cores are either 333MHz or 400MHz FSB
  • Fastest Thoroughbred core ever: the very-rare 2800+, which used a 333MHz FSB
  • 2600+ is available in both 266MHz-based and 333MHz-based versions, yep. Both flavors are available at MonarchComputer.com, a reputable vendor

Now for the harder question, what about your EPoX...

*rummage, rummage*

Well, the latest BIOS says it improves stability with the 2600+, therefore it must support 2600+ at least at the 266MHz bus speed (officially). If you want a faster system than that, you should consider getting an nForce2 board and a 2500+ and then overclock the living daylights out of it 😀 nForce2 will outperform KT266A by probably 10%+ using the same CPU, and offers lots of other goodies too... high-quality onboard 6-channel audio and Firewire (on models with MCP-T southbridge), USB 2.0, better PCI-bus performance, and support for all AthlonXP's ever made (models with onboard video don't officially support 400MHz-FSB processors, however).
