Finding RAM for the White MacBook

DIMM Slots:	2	RAM Type:	So-Dimm DDR2
RAM Speed:	667MHz PC2-5300	Default Amount:	512mb

How does more RAM help me?

Applications like Adobe Photoshop or Garage Band all store temporary data in the RAM, so more RAM will help these applications run smoother and quicker. More RAM also improves system performance when you feel the sudden urge to simultaneously open 20 Safari instances.

What type of RAM will work?

The Black and White MacBooks use DDR2 667Mhz So-DIMM RAM.

The most you can have is 2Gb, and there are two slots so you may have no more than 2 sticks of RAM.

The two sticks don’t need to be identical, however, Apple recommends installing RAM in matched pairs for maximum efficiency.

How much RAM do I need?

This depends entirely on what kind of work you do. If you multitask often or you play games, go for 2Gb. Most users will find that 1Gb is enough RAM for basic use.

What’s the difference between RAM Manufacturers?

Simply put, only a handful of companies actually manufacture the RAM, the rest are resellers.

The largest manufacturers are Samsung, Micron, Hynix, Toshiba, and a few others.

For instance, Crucial and Mushkin are both recognized names in the RAM world but both are just resellers.

The main difference between them is what type of RAM is being bought and resold.

Companies like Corsair and Crucial buy and resell high quality RAM.

Companies like K-Byte and AllComponents might sell you RAM that will work, but you’re more likely to run into problems.

Samsung, Kingston, Corsair, Crucial, PQI, Mushkin, G.Skill, and Geil – in no particular order – these are the names I would recommend.

Where should I buy the RAM?

If you live in United States, Newegg is a very good hardware reseller.

If you prefer Amazon, this 1Gb stick of Kingston RAM will work just fine.

If 1Gb is too much, this 512mb module will work as well.

Buy.com also offers the Kingston 1Gb module, and for less money than Amazon.

Lastly, here’s a list of compatible RAM modules available from OWC.
