View Full Version : First MB Pro - why only 2 gB RAM?

18th January 2008, 12:59 AM
I have the first generation MacBook Pro - 2.0 gHz.

I've seen the "adress RAM issue" topic here.
Is that the answer to this question as well:

Why is 2 gB RAM the limit on my MBPro?
- The Intel Chipset inside supports 4gB

What will happen if I upgrade to 3 gB RAM?

Hope you know the answer to this :)

4GB is for Santa Rosa chipsets.

If you upgrade your Core Duo to 3GB, or 4GB, you address 2GB only.

I'm almost certain the first generation MBP will unofficially address 3Gb, they said 2Gb at the time because 2Gb DIMMs didn't exist when it was launched.

Am I wrong?

Its like the Rev B Macbooks support only 2Gb, but apparently can use 4Gb, or so one of the guys at work who has tried it tells me.
