I have a 2010 refurbished- MacBook Pro 15". Bought a 4 gig RAM card from OWC to replace one of the 2 2 gig RAM cards. Apple's instructions on replacing RAM states you should have identical cards in each slot. How important is this? Do I need to buy another 4 gig card or just see how things go? Thanks for your input.

It boots up and recognizes the old 2 gig and new 4 gig cards isting RAM as 6 gigs.

Matched pairs are best in terms of optimal speed and performance, but not required. And for many uses, the "optimal" speed of matched pairs will not be anything noticeable in daily use (you might see it reflected in things like program load times or read/writes, if you measure such things with a sub-microsecond stop watch).
Some uses may see a difference - things that are reading/writing to RAM a lot, like video rendering, or large scale statistical modeling or other memory intensive and long running processes.
Thank you. My son does some video editing. If things seem slow I'll buy its match. As long as I'm not harming the computer.

Are matched Pairs a must for RAM Sticks
