Question regarding netbooks cpu and ram combinations

I have a question i was wondering if anyone could shed some light on.

I'm looking at a couple of Acer AOD250's, and one of them has an Atom N270 and the other an Atom N280. The difference is the N270 is 1.60 GHz w/ FSB 533 MHz. The N280 is 1.66 GHz w/ FSB 667 MHz.

The strange thing is that the ram that comes with the netbook with the N280 chip is rated at 533 MHz, but the ram that comes with the N270 netbook is rated at 667 MHz.

Shouldn't they be swapped to make them run optimally? I've looked around for an hour and don't see anyone bringing this up. Am I missing something here?

 

Are you looking at these in a store or on line? If so, then it is marketing designed to keep costs down and fool people into looking at the specs and saying "Look this one has better RAM" or "Look this one has a better processor". It makes little difference to the actual operation of the system, it is just marketing.

 

im looking at them online.

im just asking because if i buy the one with the N280, and want to upgrade the ram to 2gb, i should buy DDR2-667 to match the cpu's fsb, and not DDR2-533 to match the factory ram, correct?
