DDR200 vs DDR400 Is it that much faster?

I currently have:

P4 3.0GHz
ASUS P4P800SE MB
PC3200(200) - 1GB RAM

I want to bump up to a total of 2GB or RAM. I'm thinking I can either
get another GB of the same stuff or get a full 2GB of PC3200(400). My
question is, is it really going to make that much of a difference (200
to 400)?

Also, I have an FSB rated at 800. It looks as though as fast as I can
go with my setup is 400. No?

There's no such thing as PC3200(200) versus PC3200(400).
There is PC3200, and anything else that is not PC3200 (like
PC2700, PC2100, etc).

You don't mention how many memory slots your board has or
how many modules you have to make up the current 1GB.

Buy PC3200. Forget whatever you're trying to imply as there
is no applicable term of "200" or "400". that is the whole
reaon for the "PC3200" term. Ignore websites falsely trying
to describe memory as "DDR" terms the way a FSB is
described, because it is not, that is why PC(nnnn) terms
such as PC3200 exist at all.

Forget what you think you know and just buy PC3200 memory.
 
A bit of confusion here. PC3200 DDR RAM runs at a FSB speed of 200 MHz.
And since it is DOUBLE Data Rate (DDR) RAM it runs internally at double the
speed of the FSB, thus at 400 MHz internally. So, you already have the
right and ONLY RAM that you need: PC3200. There is only ONE type of PC3200
DDR RAM.

I got on Crucial website and they said I can use:

PC3200,DDR PC2700,DDR PC4000

I have 4 banks, 2 already banks with PC3200 for a total of 1GB RAM. I
need more RAM and I simply want to buy what I really need and what will
work.

# USB Support: 2.x Compliant
# Error Detection Support: Non-ECC only
# Chipset: Intel 848P
# Supported DRAM Types: DDR SDRAM only
# Module Types Supported: Unbuffered only
# Max Unbuffered DDR SDRAM: 2048MB
# Max Component Density: 512Mb
# 184-pin DIMM Banking: 2 (2 banks of 1)
# Graphics Support: AGP 8X

Are you sure you looked up the right board on the Crucial
web site ? What was your motherboard model number again,
exactly ? The info you copied above, mentions a chipset
of 848P, and yet you claim to have four DIMM slots ?
I'm not sure the copied blurb above, matches the board
you've got.

The P4P800 family uses DDR memory, and PC3200 is a
good choice. PC4000 is used by overclockers. PC2700
only makes sense, if the memory was really really cheap.
For most purposes, the PC3200 is fine, and that is
what I use in my Intel S478 board of the same
vintage.

Please confirm the motherboard model number.

The P4P800 SE is 865PE chipset.

There are four slots in the board. You have 2x512MB already,
and if they are in the correct slots, it should register as
dual channel in the BIOS.

You could purchase another 2x512MB, and it would be best
if they match one another. That would give you 2GB total,
which is a good round number.

You could also purchase 2x1GB PC3200, for a total of 3GB.
But the 2GB configuration would be a couple percent faster,
due to interleaving in the Northbridge.

I've used 4x512MB PC3200 in my 875P chipset board, and didn't
have any problems.

Thanks Paul, I'll another 2X512.
