Ok thanks...I had a pretty good suspicion that had something to do
with it...I am currently running at 1100 which I will continue to run
at until my new ram gets here Thanks!

well to run an XP3200..you have the wrong ram..PC2100 is 133 .so you are
overclocking your memory by 67 mhz trying to run the CPU..not good. You need
PC3200 for that ..other than that the max you can run is 133 x 11= 1463
MHZ.So you need that mem upgrade soon.

Why not try setting the CPU clock to 200MHz, then set the
Memory Frequency to 66% ? That will run the PC2100 memory
at DDR266, while the FSB is at FSB400 (the rated speed of
your processor front side bus).

The Nforce2 can be picky about the RAM you use with it,
so it is still possible it won't run properly when set up
that way. If that is the case, I guess you'll find out
what is going on when your new RAM gets here. I couldn't
get above about 185MHz until I got some new RAM, and now
I can do 200MHz no problem. So, your new RAM might make
the difference.

Something to be aware of with 3200+ processors, is there
has been a bit of fraud with them. Some people on Ebay
sell processors that are remarked 2500+ processors. There
are even cases of internet retailers selling the same kind
of crap. It can take some careful examination of the bridges
on the top of the chip, or look for conductive paint applied
to the bottom of the chip (with some color matching paint put
over it, to hide the modification). One remarked processor
was "adjusted" to demand more than the normal amount of
Vcore, which kind of "gives away" the forgery. You don't have
to assume every 3200+ is a forgery, but if you find it still
won't run at 200MHz with your new RAM, I'd pull the chip out
of the socket, clean off the thermal compound, and have a
careful look at what you bought.

The only part of the processor that cannot be faked by modding
the bridges, is the family code inside the processor. CPUZ
will tell you it is a model 10 (a Barton), and that is the
only parameter you can trust, because it is a parameter which
is stored inside the silicon die. The rest of the processor
info is configurable, and a good remarker will start with a
2500+, because all that you need to change is the FSB code
to read 200MHz. Some remarkers don't even bother with that,
and they just replace the label on the top of the chip with
a fake 3200+ label (the font used sometimes looks screwy).
In a case like that, the processor comes up at 133MHz or 166MHz,
and the user simply assumes that the speed has to be set
manually. But if the processor isn't happy at 200MHz, or it
needs the Vcore bumped up a bit, that could mean things are
not what they seem.

If you look at the info here, you can see how easy it is to
use a 2500+ to fake a 3200+. Changing the clock speed from
166 to 200MHz is all that is needed, and if the processor
comes up asking for 166MHz by default, I'd be asking a few
questions...
