I still have 7-8 of the ole DLT3C 1700/1800+s. Correct me if I'm wrong, but don't these overclock better than the present Barton/Thornton or whatever chips?
What's the big deal with the later chips? Lower VCORE or something?
You have access to newest/latest technology in Japan before we do, don´t you? What are the prices like in Japan?
Anyway:
1700+ or 1800+ DLT3C B (not A) are known to overclock further than other T-Bred B´s and at lower voltages.
However, Bartons have twice the cache of T-Breds (512 instead of 256 KB) so that's worth 100 MHz or more.
The deal with later chips is that even if they are locked they overclock further and at lower voltages.
So, even if your multiplier is locked, if you have quality PC3000 or PC3200 RAM you can overclock further than with old chips (on average).
2500+ is multiplier locked at 11.
11 x [FSB] = MHz speed.
There are cases where you can have an old Barton that is multiplier unlocked but only does 2.3 GHz
which is less than a new multiplier locked Barton that easily hits 2.4 GHz with adequate cooling (on average).
All you need is RAM (and mobo) that can hit high FSBs.
So you can have a new locked Barton that can hit
11 x [220] = 2420 MHz
Old unlocked Bartons are on average useful if you do not have RAM that can hit FSB way into 200s.
So again,
on average,
brand new multiplier locked Bartons overclock further than old multiplier unlocked ones, BUT you need quality PC3200 or PC3000 for new locked Bartons.
1. MHz speed = Multiplier x [FSB]
2. Average overclocks with adeqaute cooling is 2.3, maybe 2.4 GHz for all T-Bred B´s and Bartons.
3. List of Multipliers is in the right column of this table:

so do the math for (locked) Multipliers x [FSB]
Good luck.
