Upgrading RAM

[lil_DK]

Hey !
I currently own a HP 2000 2209TU laptop which has 2 gb DDR3 RAM and whindows 8 64 bit OS.
Whenever I turn on the internet over WiFi, and open chrome, my Laptop starts to lag very very much and finally runs into KERNEL DATA INPAGE ERROR.
As a result if this I cannot use Internet on my laptop.
I personally think that upgrading my ram to 8gb will remove the problem.
I live in India and I want to upgrade the RAM on my own.
But,I am unable to choose the RAM with correct specs like ram speed,low voltage or something!
Can you guys please help me!
Thank you!!

Here's the Manual:

It will accept 2 x 4 gig modules of DDR3-1333 SO-DIMM. See p. 45 for "how to". 

This is the HP Part number

4-GB (PC3, 10600, 1333-MHz) 621569-001

Above is DDR3-1600 1.5 volt which will downclock to 1333 and run fine.

You would probably see a major improvement for a very small cost even if you just added a second 2 gig module to have 4 in total.
