In the current system there is a 2GB DDR3 RAM in one slot another RAM slot is free. I found the following info using PC Wizard -
Manufacturer : Samsung
Part Number : M471B5673FH0-CH9
Type : DDR3-SDRAM PC3-10700 (667MHz) - [DDR3-1333]
Format : SO-DIMM (67.6 x 15)
Size : 2048MB (2 ranks, 8 banks)
If instsall a 2GB DDR3 1333MHz will it be okay? or I've to check and match other parameters? Is it required to match the manufacturer?

Hi:
As long as they have the same specs as I posted above, any brand should be fine.

Hi, Sam:
Yes, you can install a PC3 -1333 chip but it has to be PC-10600.
These are the specs you need for a 4 GB module.
- Module Size: 4GB
- Package: 204-pin SODIMM
- Feature: DDR3 PC3-10600
- Specs: DDR3 PC3-10600 • CL=9 • Unbuffered • NON-ECC • DDR3-1333 • 1.5V • 512Meg x 64 •
If you have a 64 bit operating system installed you may as well max out the memory to 8 GB while it is cheap.

My Laptop is running with a 64bit Win7. :smileyindifferent:
Current RAM is PC3-10700. Why do I need PC3-10600?
Actually I wanted to know the specs to install a 2GB RAM to make it 2+2=4GB. Buying a 4GB RAM will cost more.
Anyway, If I buy a 4GB, toatal RAM will be 6GB. Will it be okay?

Hi:
I don't know that you can buy PC-10700 memory.
The program you have probably rounded up the speed from 667MHz to 700.
If you do not purchase PC-10600 rated DDR3-PC1333 memory, it probably won't work. I know that they sell PC3-10666 and it won't work.
6 GB of memory will be fine. That's what I did. Bought a 4 GB chip. Had 6 GB. Saved some money and bought another 4 GB chip.
If you get another 2 GB module, one day you will say..."I wish I had upgraded to 8 GB of memory."
Then you wasted your money on a 2 GB chip.
But if you want to go with 2 x 2 GB...these are the specs for a 2 GB chip:
- Module Size: 2GB
- Package: 204-pin SODIMM
- Feature: DDR3 PC3-10600
- Specs: DDR3 PC3-10600 • CL=9 • Unbuffered • NON-ECC • DDR3-1333 • 1.35V • 256Meg x 64 •
