Macbook pro Memory

topic posted Sat, October 20, 2007 - 9:38 PM by  Jaime Tormen...
Hello, I just installed 2gb of memory in my Macbook Pro Core duo. It is working perfectly, despite what the manual warned that I had to use 2 modules of 1gb each.
My question is if there is a way (maybe thru software) to increase the memory up to 3 or maybe 4gb. I ask because this model is supposed to only support up to 2gb max.

Thank you very much.

    The specs (as per Maxtracker) say you can install up to 4GB but only 3GB will be addressed

      OWC has a page with test results for various ram set-ups.

        Thank you for the link, but my problem is that I have a core duo and it seems not to be possible to expand the ram more than 2 gb. I dont understand this limitation taking in account that I have one spare space for more memory. I originally had 1gb and know I have 2gb in one chip, but it doesn´t seem to be possible to have both working at the same time.

          "The tests that follow show the performance of different paired and non-paired memory configurations. Apple Core Duo processor equipped models are limited to a max of 2.0GB Memory Addressable, while Apple Core 2 Duo equipped models allow up to of 3.0GB Memory addressable." OWC

          If it works well with the 2gb single stick, great. If you have the original 512mb chip, you could put it in slot 2 and see if it sees both. Someone else here might know how to test for addressability.
