All XP2100+ and lower rated tbred cpus will be unlocked from the factory, allowing multipliers 5-12.5 to be adjusted in the bios of ANY MOTHERBOARD that supports the processor.

All XP2200+ and higher processors will be unlocked for multipliers 13-18.5 on ALL MOTHERBOARDS that support these processors. In order to adjust the 5-12.5 multipliers on the XP2200+ and higher processors you need to join the 5th/right-most L3 bridge. See this thread for explanation.

All KT400 and Nforce 2 boards will allow you to adjust ALL the multipliers from 5-18.5x with no modification.

More information on the different bridge configurations, including which L11 bridges to cross to change your default vcore and L3 multiplier settings, are available here.

To determine if you have an revision 'A' or 'B' code, please read Ed's article.

Hope you find this helpful, I will try to update this as often as needed. Please feel free to reply with any revisions, found mistakes, or general knowledge that pertains to throughbred overclocking. It will be helpful if we could round-up all the revison codes for these tbreds and have them listed here as well.
I LOVE WARE PERFORMANCE THAT COMES HARD TO GET!!

IF ITS NOT A RIGHT ANGLE ITS A WRONG ANGLE

I believe the XP2600+ 333FSB is clocked @ 2083MHz. At least thats what I've seen in online stores and from what people have been saying. speculation says its that way so the 2600+ 333FSB has no real advantage over the 2600+ 266FSB.
