Memory Speed?

Probably a simple answer to this, but I'm confused.

Optiplex 330 here with E4500/2.2 GHz cpu and 800 MHz "Memory
Bandwidth." Uses NON-ECC DDR2 memory. What speed memory do I need to
get the full benefit the system offers. Some say 667 MHz, some say
800 MHz.

Currently 1 GB of 667 MHz, but I want to bump it up to the full 4 GB
and with only two mem slots that means the current 1 GB is orphaned.

Windows XP Home SP3. Yes, I know I may only be able to use 3.5 or so
of the 4 GB.

Thank you.

800 MHz is correct but doubt you would see a difference.
