Doubt about upgrading RAM

[Siddharth Maurya]

My current PC specs are..
Processor: intel core i3 540 @3.4 GHz
Mobo: intel DH55TC
GPU: Nvidia Geforce GTX 750Ti
RAM: 2x2 GB (TOTAL 4 GB) @1333MHz
PSU: intex @450 Watt

Ok, Now I am thinking of upgrading my RAM to 8 GB, I read a lot on web that, simply adding more 4 GB RAM to get total of 8 GB is not a good idea, So now I will have to buy new 8 GB RAM, but how? according specs of my mobo it supports Maximum of 16 GB RAM @1333MHz...so will my new RAM still work if it is @1600MHz...If yes then I'm thinking of this one--->

(G.Skill Sniper DDR3 8 GB (2 x 4 GB) PC DRAM (F3-12800CL9D-8GBSR))
So suggest me, will my current spec support this RAM & is it good idea or I need to think something else?

Your system supports this RAM, and it should work fine. It is a good idea to get rid of your old sticks and get 2x4 GB new ones, so you can be more sure they are a good pair for dual channel operation.

If your board supports only 1333MHz, this is no big deal - and if you get 1600 MHz, it will work as 1333 on your mobo. No harm done.

I just found this.....

he says that my Mobo won't support 8GB stick, so I have no other options than 2x4...am I rt? .... wt is that high/low density thing....should I consider this in matter?
PS:
and another doubt....
as I have four slots...can I just keep my current 2x2GB dual channel as it is and add another 2x4GB dual channel in other two..to get 12 GB?

You have an older mobo that was designed to work with the low density memory chips that were the then 'common chips' used - Post 2010 DRAM manufactures have moved DDR3 to high density memory chips, like the Snipers, I'd look for the older low density sticks, GSkill NT series of value DRAM is still available

Thank You for your Answer!

I read somewhere that my Mobo supports PC3-10600 type RAM, so is it true?
according to that, I found these...

Is there any way to identify a RAM if it is high density or low density?
