Hi guys im a big fan of tom's hardware, and its my first post. Newbie. 
I recently bought this rig here are the specs,
I5-4690k
Asus b85-pro gamer
G. Skill ddr3 1600mhz 8gb
Geforce GT 9500 1GB(Old school)
Seasonic M12II bronze evo 850w
Questions:
When i bootup my bios, i see my Ram specs however i only see 1333mhz. My concern is i bought a 1600mhz and its showing up 1333mhz, will it affect my performance? Do i need to make adjustment on my bios?
Note: i just assembled this so all settings are just like plug and play i am still afraid of bios, lol.
