A Duron 1800 runs really well in this board. I have 3 of these setups. Don't
forget that this processor runs at a full 1800 mhz., which is the equivalent
of an Athlon XP 2400 and almost as fast. It's a great choice budget
processor.

Who is selling a Duron 1800MHz in the UK at a good price? Dabs.com
is doing them for £32 plus about £2 P&P. <a rel="nofollow" style='text-decoration: none;' href="http://snipurl.com/5hgb" target="_blank">http://snipurl.com/5hgb</a>

For £39 they sell an Athlon 1800+ which seems much better value.

I think my Via KT266 chipset doesn't support T-bred or Barton. I
think I am limited to only Palomino.

Do you know where on the AMD site it has info on Duron power
consumption. This is the closest I got:

That's Intel lingo. AthlonXPs uses the DEC Alpha EV6 bus for FSB. And
it's 266MHz (or 200/333/400). More specifically, it runs on a 2X
multiplier on the (FSB-) clock that also controls cpu-speed via
another multiplier. The FSB is not the memory bus. The FSB connects
the cpu to the Northbridge.
The memorybus is between the Northbridge and ram. And DDR266 (double
data transfer rate) runs on 133MHz.

You think wrong. The KT266(A) chipset will support any AMD Athlon/Duron
cpu. Any. And while it will run any, the FSB is limited. Tbred and Barton
cores also run fine on the very first socket A VIA chipset, the KT133,
which you see below. As will the newer cores. See link in sig.

My BIOS is the same. PSU is 250W.

At the price that is unlikely to be a stable PSU or to really
delivery all the power it claims. Call me cynical! Heh!

I want to have something like a Nexus 3500 which is not only stable
and really delivers the power which it claims but is also quiet.

Actually, the 500W PowerMagic PSUs aren't half bad. You can easily run a XP
dually off them, so should be able to handle pretty much any uniprocessor
system.

Doesn't the Barton core run on a 333 MHz FSB - putting it outside of the
OP's parameters ?
Thoroughbred core XP2400 runs 266 MHz FSB and the early XP2600 did too -
though newer ones are 333 MHz FSB.

There are mobile Bartons that use DDR266 FSB, but they default at 6X
multiplier, the motherboard must have the ability to manually set the
multiplier higher. Even so, since they default to 6X (a multiplier under
13X), they're stuck in that sub-13X range since the board likley doesn't
have full multiplier selections, so the maximum resulting speed without
any hacks or bus overclocking is 12.5 mult X 133 = 1.67GHz.

However, we still don't even know if the present motherboard will even
support any Barton... the suggestion I made in the prior post was right
after I'd written "I'd be thinking about upgrading the motherboard and
memory", with the presumption being that the upgrade would be a fairly
modern motherboard with Barton & DDR333 FSB support.
