Any point in using PC4000 memory?

Hi all,
Is there any point in buying PC4000 or even PC4400 memory for my
P4C800E-DeLuxe, since it will only be run at 400 (2x200) MHz?
It's a lot more expensive than the PC3200 variety...
Thanks

Not unless you plan to overclock the he** out of it.

If you do not intend to overclock no. At present I am overclocking a
p4 2.8ht and PC3700 ram at 948 fsb (intead of 800 fsb) CPU:ram ratio
is 1:1.

If you use slower ram and overclock you will eventually have to use a
slower ram ratio to maintain stability.

If the price diff is not too great go for the faster ram, but don't
go to value ram (the name says it all).

Generally no need for the fast stuff. Intensive operations like video
encoding on P4 systems can benefit from memory that can handle fast
timing settings o/w save your bux.

If you don't overclock, most PC3200 will run faster than PC4000 at 200 MHz,
because they can run at better latencies (cas 2-3-3-6 or better), while
PC4000 have generally latencies of 3-4-4-8 or worse.
If later on you should decide to overclock, you could still set the mem
ratio at 5:4, which allows you to increase the fsb speed up to 250 MHz where
the DDR reaches it's nominal speed of 200 MHz.

Thanks guys,
Now I am beginning to understand where these ratios came from- memory!
I thought it had something to to with the Pentium P4 ratio- which is
fixed.
Cheers

Only if you want to overclock, or use it in your next system which will
likely have a higher FSB.

you can alter the memory timings though so with pc4000 you may get fast
timings between 200-250fsb.

Actually, that is not the case. Many PC4000 sticks flat will not run below
CAS 2.5.

Too true. I've got two sticks of OCZ PC4000 Gold running in a P4P800-D
and they run fine at 260mHz @ 1:1 but start crapping out if I try
tightening the timings (even at 200 fsb). I suspect I could go faster
but this motherboard only supports 2.85 VDIMM (and I'm not comfortable
trying to mod that).
