I gues I should have included the example:

This should not show up as C2, however.

Some of the PC3200 Corsair memory is 8-3-3-3 at 200Mhz. For example:

Here's your memory (
http://www.corsairmicro.com/corsair/...512-3200c2.pdf ),
says
nothing about PC2700, so I don't know where that's coming from. Suppose
to
run 200MHz clock, 2.5-3-3-6 on AMD, a little faster on Intel (2-3-3-6).
I
assume this is the SPD results during config.
So there's no reason you shouldn't be able to run the Athlon (@ 166MHz
clock) in sync (1:1) w/ your memory (underclocked @ 166MHz). Now, as
you
increase the CPU FSB, are you saying you are getting memory errors?? I
assume the CPU FSB will OC even a little, so it would surprise me to see
errors w/ even 167MHz (1:1).
What I'm wondering is whether maybe you're actually trying to run async
(e.g., 5:6, 166 / 5 * 6 = 200, not even sure this is possible w/ NForce2
chipset, just speculating), so therefore everytime you OC the CPU FSB,
you're also overclocking the memory! If the memory is already tapped
out
at
PC3200 (200MHz clock), especially if perhaps you're trying to run
2-3-3-6
(not the certified 2.5.-3-3-6), then perhaps it just dies at even a hint
above 200MHz clock.
I'm just speculating, but it's my guess this is what you're trying to
do.
Remember, every time you OC the CPU FSB, the memory is OC'd too! That's
why
the proper thing to do w/ this CPU and memory is run 1:1! You're trying
to
OC the FSB, but you don't want the memory holding you back. If you
insist
on running the memory "at spec", 400MHz DDR, 5:6, you're asking for
trouble!
If the memory has a little headroom left over, you'll make a little
progress
w/ the FSB overclock. If not, the FSB overclock will die a quick death.
It
sounds to me like this latter scenario is the problem

I have a quick question about my memory and setup in terms of
overclocking..
I purchased Corsair PC3200 memory with the expectation that it can run
at
400mhz, but it seems to fail in this ambition (i get a memory error in
the
bios, have to reboot the machine). When I when I try to overclock
the
FSB
to 400Mhz in the bios (anything over 167) I get memory errors...
motherboard: A7N8X 2.0 (which should run at 400mhz ..)
cpu: AthlonXP 2600+ 333
SiSoftware Sandra reports my memory as the following (I have 2x512mb):
Memory Module 1 : Corsair CMX512-3200C2 512MB 16x(32Mx8) DDR-SDRAM
PC2700U-233-700 (CL2.5 up to 167MHz) (CL2 up to 167MHz)
Memory Module 2 : Corsair CMX512-3200C2 512MB 16x(32Mx8) DDR-SDRAM
PC2700U-233-700 (CL2.5 up to 167MHz) (CL2 up to 167MHz)
I don't understand why it says "PC2700" in there at the end, but
'3200'
in
the beginning. When I bought this memory it was listed as PC3200.
And
it
says it is limited to 167MHz, which also seems to be the barrier to
the
BIOS
when I try to overclock.. (i can't get it higher than 333mhz fsb)
any ideas as to what my problem is?
Thanks very much
