Does increasing RAM in the Laptop cause any problem

[Ankit Saxena]

I have planned to purchase a laptop of Sony Vaio. It's a low budget laptop with simple configuration. Core i3 processor, ! Gb graphic card, 2 gb RAM.
The dealer has assured me that he will add a 4gb RAM. (As it has one unused slot). My question is that will there be any problem if i'm increasing RAm of my Laptop coz i have heard some people saying their laptop has caused some problems (like pc hangs) after RAM upgradation. Is it so?? Will it cause any problem in my case?

there could be problems if the new RAM is different from the original one... mixing different RAMs is bad even in desktops

It can do, Check if he is adding 4gb, or adding two to bring it up to 4gb.... If the dealer is any good, he should be adding an identical stick (adding 2gb to make 4gb) of RAM to operate dual channel mode. Which would be better than bunging an extra 4gb of RAM in single channel... It's simpler too. I would frown at a vendor offering me mismatching RAM, and would probably take my custom elsewhere.

What does mixing two different RAM actually mean? Does it mean RAM with different sizes or any other technical differences?

Different size, latency, or speed, they have to be identical to operate in dual channel, which is almost twice as fast as they operate toggether. Think of it as a RAID system in ram

first of make sure it is supported by your laptop speed and capacity, but your best shot is to get too identical parameters RAM modules for dulal chanell
