Is this RAM 1066 or 1333 MHz?!

[iwih]

Hi everyone,

My laptop is HP ProBook 4520s - XX833EA#ABV, I want to upgrade its ram from 4 GB to 8 GB, but, I need to know the bus of the RAM included in the device. When I opened the laptop I pictured the RAM, these are the pictures of both sides:

I really confused about it, the serial number on it shows that it is 1333 MHz, when the CPU (Intel Core i5 480m) supports only 800 or 1066 MHz... So, what's the frequency of the current one??!! Please, I want an absolute answer

Is the current one compatible with this one:

Thank you in advance

It's ddr3-1333 clearly.

You need another 1333 stick of the same voltage and timings to match the one you have.

If there is no voltage indicated then you just need another stick of 1333 cas9 latency.

I would get the 1.5v.
