MacBook RAM In Pairs?

[bekabug]

Can you put in one SO-DIMM and run the MacBook or do they have to be installed in pairs?

Pairs aren't required. They do give a tiny speed boost, which is helpful to the MacBook since it uses shared main memory for graphics, and that's why Apple recommends pairs in the MacBooks.

If you want real world numbers:

...and you'll notice that single (or unmatched) sticks are just fine, and in fact the speed difference is tiny.
