Certain KT333's will. I posted on this before and was told that my 8K3A will work.

Any idea which multipliers are unlocked?

If the mobo supports the unlocked multipliers, it's the same as the Nforce 2 ones.

I have a Tbred A 1700+ on an Epox 8K5A2+ (KT333) that is unlocked at 12.5 and below, just like the NF2.

Which BIOS are you using?

Strange, on my Epox 8K5A2, (using 8/15), I can't even change my 2100+'s Multiplier to default (13x). It won't even post.

Though, I havn't tried any other multipliers, strange it wouldn't post to default multiplier.

Very Bizarre. My BIOS is also 8/15. I see on the Epox Website that there are updates for both of our motherboards, however. There's a 10/25/2002 for yours and a 11/01/2002 for mine, and both claim additional AMD XP support (333FSB chips), etc...

I'll wait and see what my 2100+ will do on this mobo (it's on it's way here) before I update the BIOS on mine.

This is not true at all, it has nothing to do with the motherboard. I run a MSI K7T266 Pro2-A using the KT266A chipset with a AMD 1700+ XP and I was able to increase the multipiler to 12.5, but not any higher. I read that you need at least a 2100+ to achieve 13 and above. My fsb is only at 142 Stable, cause of my memory.... that reminds me any recommendations to a starving college student for good ram? cheap please. :) I current have Samsung 2100 512MB 2.5CAS

maybe because they were rushing out the T-Bred B's(XP2400+ - XP2600+) after intel got the lead
remember they were paper launched
so maybe AMD's engineers didn't have time to devise a a new lock(L1)
