How should I configure unequal RAM?

I was under the impression that slots 1&2 should be used for the higher capacity sets and 3&4 for the lower.

However, I found this verbiage on the apple support page:

"If your DIMMs are mixed in capacity, minimize the capacity difference between Channel A (slots 1 and 2) and Channel B (slots 3 and 4) when possible."

If I am reading that correctly, the slots should be ordered as 1-big, 2-small, 3-big, 4-small.  That would equalize the two channels.

When I look at "Memory" on the "About this Mac" function, should the larger capacity DIMMs both be at the top?

Not a big deal to rearrange if needed, but I thought I'd check here first.
