P4P800 RAM question

I currently have two sticks of 256 meg DDR400 RAM with this motherboard
running in dual channel mode. I was considering adding another two sticks
of 256 meg DDR400 RAM, for 1 gb total. My question is will using all four
memory slots decrease my memory bandwidth if I'm using two now? I'd like
the extra memory but I wouldn't like to drop in speed.

Thanks
 
"You should install as few RAM modules as possible. Reducing the number of
chips on the module will also enhance performance and stability. The
modules generally consist of eight or 16 chips.

The number of memory modules you use will have a direct impact on your
command rate. The command rate specifies the number of clock cycles the
memory controller needs to activate the modules and chips. If you've filled
all your memory banks, you'll generally have to increase the rate from one
to two clock cycles to keep your system stable. Unfortunately, that will
also impair performance by up to three percent."

This is WRONG! For the love of god people, PLEASE stop quoting Tom's
Hardware! The Command Rate is FIXED at 1 on all Intel chipsets, at
least since the i815.

I tried to find this piece of information in the web, but did not succeed.
Would you be so kind and give me some link(s) related.

TIA

PS. Is it so or does it just look so that you don't trust Tom's Hardeware
Guide much? Any reasons? For me, they're doing quite a good job...

You should be able to deduce this simply by knowing that Intel has
spec'd 4 banks max for several years now, but here you go:
