RAM frequency is lower than specified

[prathameshm1612]

I purchased an hp laptop and it shows the RAM as 4 GB SODIMM 1333 MHz.
The RAM specifications as given on the site are 4 GB 1600 MHz DDR3.
The laptop was given for repair at hp service center because the original RAM was defective according to what hp told me.

Is the new RAM same as the previous in terms of specifications ?
I am not as good at computer hardware so I'm sorry if you feel the question is very childish.

The RAM is likely 1333 able to be 1600 with O.C.

My one friend in Mexico had a similar issue with a Core i7 build that was only running at 1333. Maybe this article will help about the XMP configuration in BIOS to get it to 1600.
