The success rate of overclocking XP2500+ to XP3200+ (2200MHz) is very
high...In fact with the more recent cpu's I've never heard of a failure. I'm
currently running a locked XP2600+ at 2560MHz.

Thanks. I'll check it out.

Have you been successfull at overclocking a multiplier-locked Barton 2500
from 166 x11 to 200 x 11? Is that to ambititious of me?

I'm thinking that if I can't get this 1833mhz processor up to at least
2100mhz and beyond, then it's not worth the upgrade. Currently I am at
180fsb which gives me 1980 mhz.

I just bought the Barton cpu so I don't want to get rid of it just yet.

I am running a Barton 2500+ on a Ga-7vax mobo. I would love to be
able to overclock this cpu since the cpu is barely breaking a sweat
at default 1833mhz (load temp 29-32c) . The mobo allows me to switch
multipliers by switch but the cpu seems locked at 11. Odd enough,
even if I lower the mulplier the cpu is still at 11. Its as though
the cpu is ignoring the mobo and won't even allow unerclocking.

My next step was FSB. Since I am using 512 mbkingston ddr3200 ram
which easily clocks to 400mhz, I can up the FSB to 200- except that
the PCI divider screws me up. 180is my max.

Should I get an nforce mobo? is it worthwhile? What kind of
performance increase will I realize if I up the FSB to 200 x 11 vs
the current 180 x11 speed?

The sole reason I left VIA Socket A chipsets for the nForce2 is the PLL
PCI
divider issue. I had several Gigabyte boards which, while solid and easy
to
work with, did not overclock very well. Look at the Abit NF7/NF7-S or
the
Asus A7N8X series of boards.
