Questions & Answers for Apple Memory Module 4GB 667MHz DDR2 (PC2-5300) - 2x2GB SO-DIMMs

No. This is R.A.M (Random Access Memory) which is the volatile memory that is lost every time your computer shuts down. These circuits store information in statically charged pockets in the silicon of the chip. When you shut down your computer properly, anything in memory needed to be kept is copied out of ram to your disk or non-volatile memory. When you power down to remove the old memory module it will already be empty. Therefore it is not necessary to back anything up before removing it.

Ideally you should take out the memory you have an insert

2X Memory 2 GB 667 MHz DDR2 SDRAM taking it to 4G

But that is often harder to find and more expensive

You are *probably* safe with
2 X 2 GB 800MHz DDR2 SDRAM
I inserted one of these today and it worked fine
