I buy a ddr3 4gb ram 1600 mhz and my laptop is only using 2gb ddr3 1333mhz. My laptop model is ASUS A43SJ 2011 model, processor is i5-2310M and is it suitable to add 4gb ram 1600 mhz in my laptop? Or i can take the 2gb ram out and replace to the 4gb ram?

Ivy bridge cpu's are not sensitive to ram speeds, 1333 is fine. Read this:

Most laptops have two ram slots. You could match your current ram with another stick in the second slot to give you 4gb.
Download and run cpu-Z to see exactly what ram specs you are using. Adding a second stick will give you dual channel operation which speeds up your cpu processing a bit. Likely, you could add a 4gb stick to get a total of 6gb.
The odd 2gb would run in single channel mode.
A 32 bit os can only access a max of 4gb. Only go higher if you have a 64 bit os.

Ram is sold in kits for a reason.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will not support ram that is not bought in one kit.
Although, I think the problem has lessened with the newer Intel chipsets. Still,
it is safer to get what you need in one kit.

You want documented ram compatibility. If you should ever have a problem, you want supported ram.
Otherwise, you risk a finger pointing battle between the ram and motherboard support sites, claiming "not my problem".
One place to check is your motherboards web site.
Go to a ram vendor's web site and access their ram selection configurator.
Enter your laptop make and model, and you will get a list of compatible ram kits.
While today's motherboards are more tolerant of different ram, it makes sense to buy ram that is known to work and is supported.

That is correct, 1600 ram has a default mode to let it run at 1333.
A laptop motherboard will not have the ram overclocking options to let you run at 1600 speeds.
But why bother?
1333 is plenty fast, so no need to spend more on 1600.

If you ask for ram upgrade suggestions on a ram maker web site, they will suggest all of the compatible kits for you laptop model.
