MBP: RAM upgrade question

hello,

got new macbook pro , looking upgrade ram 4 8gb. current speed memory provided apple believe ddr3 1333 (pc3 10660). i'm wondering if, when upgrading, need stick same speed or if can upgrade speed such ddr3 1600 (pc3 12800) when purchase new 8gb modules. can't find online specifies max speed supported. can tell me max memory speed is?

many in advance!

you can use faster speed ram, not use ram @ speed, if mac os x registers them @ modules' correct speeds.
