Hello,

I recently bought a seccondhand MB for 150euro's.

the specs are:
2.16ghz core 2 duo
120gig hd
13.3" Screen
1gig stock RAM memory

i went to an apple reseller and they told me that it will only support up to 2gig of ram.

But, looking around on internet, i found out that it will support up to 3.3 gig (out of the 4 you will put in).

what do i believe?


other question:

Will i be able to run World of warcraft and CS4/5 (Adobe Creative Suite) with 2gig?


Thanks in advance
 
Officially, 2GB (that's what Apple says). Unofficially, 4GB (~3GB will be utilized due to memory overlap).

The following was taken from Discusions.apple.com:

"If you own a core 2 duo which it sounds like you do it will hold 4 GB of RAM but only use 3 GB of RAM. The 4 GBs gives best video response by giving you a matched pair. Crucial has their site set up to sell exactly what RAM amount is specified by Apple.

You can see results of tests that were run with the different RAM configurations.

OWC: MacBook Memory Benchmark Test

The only MacBook that can't hold or use more than 2 GB was the Core Duo MacBooks."

Is this true?
If yes, then my problem is solved, and i can use more then 2gig.

i have also read that i should get 2x 4gig of the same module, instead of 1x1 and 1x2, because 2x2 would be faster due to some things i dont really understand. its just faster :p



(So actually what you are saying is that i basicly can use more then 2?)

Theoretically faster, yes. Faster in real world, no. Using matched pairs will enable dual-channeling what theoretically doubles the memory bandwidth but the issue is that only very few apps can really take advantage of that extra memory bandwidth. Things like Safari and Mail won't benefit from the extra bandwidth.

Both, 3GB and 4GB will be fine.

Awsome!! thank you so much!! this was the breaktrough for keeping my mac and not returning it! :D


Could you give me a list of the programmes which do use the extra memory bandwidth? or is this really small.

There is no list of apps that do, but generally, those apps are either games or professional video, photo, audio or 3D editors.

It's not something you should worry about.
