Hello everyone!

I have been thinking of upgrading my macbook pro from its existing 2gb to 4gb so that my vmware for windows vista can work faster. I have been looking through the forums and some mentioned about a RAM cap at 3.2gb. Is that true?

Here's what my system profiler says:
Model Name: MacBook Pro
Model Identifier: MacBookPro3,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 2 GB
Bus Speed: 800 MHz
Boot ROM Version: MBP31.0070.B07

I will be obliged if someone can tell me whether I should still look into upgrading my RAM to 4gb.


Cheers,
Torrance

MacBook Pro 3,1, Mac OS X (10.5.5)

    Your computer can use the full 4GB.

    Those were the earlier macBookPro's have fun with your 4 gig. Remember to get an apple specific RAM for better performance. I just got myself a RAM upgrade a few days ago... feeeeels sooo good.

    Bought 2 kingston apple specific memory modules. Has been perfectly working

    Goodluck!

    I have a similar config:

    Model Name: MacBook Pro
    Model Identifier: MacBookPro3,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.4 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 2 GB
    Bus Speed: 800 MHz
    Boot ROM Version: MBP31.0070.B02

    I bought Corsair Mac Memory (2x2GB) and installed it. The laptop will not boot after the memory has been installed. I also tried some non-Mac memory (OCZ) and had the same issue. After pressing the power button, all I get is a black screen and a steady blinking light on the front.

    Any ideas what could be the issue?

    Thanks

    FYI - I also tried just a single stick of the new RAM (2GB) and it booted fine.

    I fixed the issue. It appears to have been related to the firmware version. I upgraded from MBP31.0070.B02 to MBP31.0070.B07 and the new memory was recognized.
