It's sold as 400MHz CL2, timing in spec: 2-3-2-6-1, but it doesn't go that
speed (400MHz CL2)
What's more CPUID shows that on 200MHz (dual 400MHz) it can go 2.5-3-3-8 and
on 166MHz 2-3-3-7.
Sys: Intel Pentium 4 Northwood 2.80GHz on ASUS P4P800.
Where's the problem? Do they lie with 400MHz CL2?

Check your bios to see whether it's using Auto/SPD setting
for memory timings, not just bus speed, or is manually set.
Use "CPU-Z" (Google will find it) to see two different
1) Again what timings it's running at to compare to what
was reported by CPUID.
2) The timings programmed into the memory and read off of
it, it's a second set of numbers on a different tab in
If these are as you mentioned above, AND if your bios is set
to Auto, you can do one of two things:
1) Assume the motherboard bios read the right SPD value for
CAS2, and is programmed to use CAS2.5 anyway to retain
stability. This is common on motherboard bios, particularly
with more than one memory module installed it may decide for
you to use more conservative timings without ever doing what
you could try in #2. The safer and more conservative answer
is to assume the motherboard bios configurator knew how to
set it up best and that you should leave it set to Auto/SPD.
2) Ignore what the bios things you should run the memory at
and in the bios menu set it manually to CAS2, then do a
whole lot of testing to be sure the system is stable (which
it might not be).
It could easily be CL2 memory, your board just wants to run
it at CL2.5.
