Ram Upgrade 2gig 2009 Unibody Mac

I have a 2 gig 2009 Unibody Macbook Pro, and would like to upgrade it to 4 gigs. Just wondering if I need to order just 2 gigs or do I need to order just 1 4 gig memory. And I was wondering if the memory was soldered in.

To see what you have, go under the Apple in the upper left hand corner to "About This Mac" then hit the more info button then hit the memory listing. That will give you your current configuration.

This is your probable Mac:

Apple MacBook Pro "Core 2 Duo" 2.26 13" (SD/FW) Specs

Identifiers: Mid-2009 13" - MB990LL/A - MacBookPro5,5 - A1278 - 2326*

It comes stock with two 1 GB RAM chips and none on the logic board.

Maximum RAM is 8 GB. You can remove and upgrade just one if you choose.
