Upgrade RAM Macbook late 2009

Hi! I need your help I have to upgrade my ram, but I cannot tell the difference between these two options:

http://www.amazon.it/dp/B0050X1OQ6/
and
http://www.amazon.it/dp/B00432UW2M/

Are they compatible with my white macbook late 2009? Are kingston RAMs better than transcend ones?

Thank you very much.

We usually recommend these two suppliers of ram. They make it easy to figure out what you need:

- Performance Upgrades; FireWire USB SATA Storage; Memory, more at OWC
- RAM Memory Upgrade: Dell, Mac, Apple, HP, Compaq. USB drives, SSD at Crucial.com

Thank you very much Nick! I'm sorry but I'm from Italy and it would be cheaper and faster for me if I bought them from amazon.it
Anyhow, I realized I made a mistake when I pasted the links. Please check out and tell me if those are compatible with my macbook.

Thank you again

Sorry...I didn't realize you were in Italy. I took a look at the links...but my Italian (language) is not so good! Sorry.

What you can do is:

- go to the links that I provided for OWC and Crucial
- from each site identify what the correct ram is for your computer (each site has an easy system for this)
- check out the specs for the ram
- then compare this info to the ram that you identified from Amazon.com

HTH,

No problem at all! Thank you very much Nick! I just have some final questions.

- Is there any difference among brands? I mean as long as they have the same characteristics (DDR3, pin, volt, timing etc) they are pretty much the same, are they not?
- Are 4gb rams already obsolete? I don't use softwares that require a lot of ram.

Thank you again

I don't think so...or at least it's very hard to know. When I buy ram...I usually like to purchase it from a place that includes a lifetime warranty in case something goes wrong.

How much total ram are you talking about upgrading to?

- 8gig of ram (2 x 4gig)?
- 4gig of ram (2 x 2gig)?
