Multiplier Question

That's not true. KT400 and everything above (maybe even KT333, not sure)
unlocks AMD (not sure for Palomino, but Tbred definitively).

I have the KT-333 on an abit KX7-333, it will run tbreda and b and barton
core CPUs at any multiplier

The problem (it seems) here is that the OP is trying to overclock a palomino
core CPU, these are a pain to unlock (trust me i had one). If it is a
palomino, i urge them to get a new chip, even if it is a tbredb 1700+<!-- ~MESSAGE_AFTER~ -->

Any Tbred B is unlocked by default - ie. all the L1 bridges are intact. On
an NForce2 motherboard (& perhaps VIA KT600 ?) the whole range of
multipliers are available. KT333 &, AFAIK, KT400 only have the range of
multipliers available that the CPU is preset for - eg. 2400+ spec is
15x133.3 for 2.0GHz thus the range of multipliers available is preset to
 >=13.5x - to make the lower range (<=13x) available for overclocking the FSB
to 166 or 200MHz; You can join the fifth L3 bridge with a 'U' of conductive
paint without having to fill the Laser cut pit. Eg. I'm running my Nov'02
(ie. 'old'.) 2400+ at 11.5x196 for 2254MHz on an Epox 8K3A+. (VIA KT333.)

Any Palomino requires unlocking on any motherboard, NForce2 included - ie.
all the L1 bridges are cut & require rejoining to use anything but the
default multiplier. This is no easy 'pencil trick' job on Palomino - you
need to fill the Laser cut pits, then join all the L1 bridges with
conductive paint - I've had a 90% success rate with Palominos; I have two
that I can't join the L1 bridges at all now because they were damaged in the
multiple attempts to join them. At least they still work anyways...

I'm unsure about Tbred A, as as I've never owned one, but, AFAICR from what
I have read, they're all locked. Tbred A topped out around 1.8GHz and that
is it's spec' anyway, that's why I never bought one...

John; Your 1900+ is most likely a Palomino which will run at 12x133.3 for
1.6GHz apec' - if it has an AGOGA or earlier stepping code, then the most it
is capable of will be close to 1.8GHz - it should do 12x150 for 1.8GHz
easily enough without any unlocking tricks & as long as you have good
cooling. If it has an AGOIA code (last of the Palominos) then it should do
1.9GHz okay with good cooling & an overvolt to circa 1.85V- ie. 12x158 for
1.9GHz...

The CPU being locked, or unlocked, is determined by the bridges on the CPU and
not the motherboard.

As another poster stated, this is incorrect. It's dependent on the
processor, itself, with the ability to do 'soft' overclocking of the
multiplyer relying on the BIOS options. If the processor is multiplyer
locked, it's locked. No motherboard, on this planet, will remove it. You
will have to, physically, remove the lock on the processor.
