Just to add a comment about RAM memory from Crucial, I and several other local Mac users have run into trouble when using memory from Crucial and they are just NOT particular or detailed enough when supplying proper RAM. And returns are a real hassle due to customs and duty etc. from Canada.
We are lucky enough to have a local dealer who is right up to date and always supplies the correct RAM. In this case the OP might notice that only the 4GB modules are listed as compatible with that Mac MC508LL/A model to get its maximum memory -
that actually works!!! :

PS: I did break down and bought a Crucial 240GB SSD BX200 on sale as I needed a cheap replacement for my non-critical 2007 MBPro that I almost had to return as it would not mount when used in my Voyager 4x Dock and connected via Firewire or Thunderbolt adapter. USB connection did.
So, just mentioning that with most experience with Crucial and their supplied RAM modules has not been good for a lot of local Mac users here. Just saying…
PPS: Never any such problems with OWC Mac compatible memory if we have to use them but CanadaRam.com is just a short drive away and always works.
