[jonahtron]

hi, im just about to purchase for my early 2008 white macbook the following...

2GB, 200-pin SODIMM, 256MX64, DDR2 PC2-5300 (crucial)

as far as i know this is absolutely fine, and mactracker tells me i need

200-pin, PC2-5300(667 MHz), DDR2 SODIMM

the only confusion im having is that the seller doesnt list the Hmz speed and i dont know what 256MX64 refers to...

i honestly have googled but found it more than a little confusing to be honest.

any help would be appreciated
thanks

256M x 64 describes the capacity of the SODIMM in megabits. If you convert it to bytes, you would multiply the 256Mb x 8, which comes out to 2GB ((64bits / 8bits per byte) * 256,000,000 bits).

DDR2 PC-5300 runs at 667MHz.

It should be the correct device, though usually sellers have a cross-reference to the make/model of your machine. Check Crucial's home site - they should have a reference there. Your User's Guide also has a description of the correct type for your Mac.

i'd be seriously lacking in form.
