Memory upgrade for VAIO PCG-K315Z

[gonkenobi]

Hi all, hope you'll help me as you have done before.

I am thinking of upgrading my VAIO's system memory. As i have read, the laptop has two memory slots each one with a 256 Mb module.

Therefore, no slot free and the only solution is to drop one of the current 256 module and put a new 512 Mb in its place, thus having 768 Mb total.

My question is : Is it possible to have
a) different RAM configuration (1 module 256 and the other 512)
b) Modules from different manufactures ( Sony's prices are far from low)

Thank you all and regards

The answers are yes to both questions. You can use different size cards and you can use memory other than Sony's.

On the subject of RAM in this topic, I have a PCG-GRV516G Vaio laptop that is now 3 years old. It has 2x256Mb ram sticks and I was thinking of taking those out and putting either 2X512Mb sticks or a single 1Gb stick in? Some say it will work but others say it won't cause of the age. At the time 256 was the only sticks you could get, but times have changed. Is it possible??

Unfortunately nothing has change in the three years that you have had this notebook as the amount of memory that it can accept is hardware related. You already have the maximum RAM that it can accept
