I'm looking to upgrade the RAM in my late 2008 Macbook, see the spec below.

A few people have mentioned getting Crucial RAM but I'm unsure of what specific RAM to get and what the limit is. Or if there's better/cheaper options than Crucial.

I'm looking to get the max amount possible I can fit in.

  • have you entered the model in Crucial's memory finder? – mmmmmm Jun 24 '14 at 13:05

From EveryMac :

RAM-Type = PC3-8500-DDR3 SDRAM @ 1066 Mhz

Supports officially max. 4GB and unofficially max. 6GB,
but indeed a total of 8GB on ROM Version MB51.007D.B03
and if running Mac OS X 10.6 or higher.

Apple released an update (including 8GB support) here.
Also check for information about it here.

And if you are unsure, which to buy: here are some on amazon.co.uk

  • Ok thanks. So if I bought 4GBx2, it could use a minimum of 4GB and a maximum 8GB of it? My ROM version is different so guessing it wouldn't use the maximum of it... but there's a chance it could? – Rob Jun 24 '14 at 13:23
  • @Rob I added a firmware update link in the answer so you can use the full 8GB. – rwenz3l Jun 24 '14 at 14:24
