Plz suggest good Laptop RAM

I have some doubts for upgrading my RAM from 4GB to 8GB.

1. How to check my current ram speed(Mhz)
2. Should I buy another 4GB or 8GB. Will it support a total of 12GB.
3. Which is the best brand now, Corsair, Transcend,...

Plz note I don't play games in laptop, main usage is as a developer machine.

Thanks in advance.

im no expert on the subject but I know laptop ram is a very tricky business ,so please be careful

only buy ram which is tried and tested by others

Thanks for the links.

Install or Open CPU-Z and go to memory tab. Note the digits written before clocks and group them as x-x-x-x. (like 5-5-5-15)
Notice the dram frequency and multiply it with 2. This is the actual frequency of the ram.

When searching for the RAM, match those values you noted and buy whatever suits you.

Thanks for the info. I think the ram is DDR3 with 1600Mhz but have to confirm.

Always follow this rule of the THumb when buying Laptop RAMS :--->

whatever may be the specs,but voltage is the most important criterion for mtching RAM modules,at least in case of laptops.

Hierachy for choosing RAM modules both for laptops and desktops :--->

type = type

Volt* = Volt*

frequency = frequency(least priority)

* Matching is a must for laptops,may not be too essential for desktops.

Listen to @ kg11sgbg he already had a experience.

I would say 4GB memory is balance in term of cost and performance. Best laptop comes in Apple.

And what has this to do with OP's query? :banghead:

For the bold part, they make touch-less tablets with keyboards, not a laptop.
