I have an iMac 2.8Ghz Core 2 Duo and it is running on 2GB (DDR2) of RAM. Since Snow Leopard is a 64-bit OS, will it support 8GB of RAM?

I know in Windows, a 64-bit OS can support upto 8GB of RAM but I wanted to make sure that was the same case in Mac. Below is my Hardware Overview:

Model Name: iMac
Model Identifier: iMac7,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.8 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 2 GB
Bus Speed: 800 MHz

    Snow Leopard supports much more than 8GB of RAM, however your model of iMac officially supports a maximum of 4GB of memory. It's a limit imposed by the hardware.

    Current iMacs support up to 8GB, and Mac Pros support up to 32GB of RAM.

    One more thing - a 64 bit computer could theoretically address about 17.6 billion GB of RAM!

  • The following is how I configured my Mac. The memory I added in myself.

    Current O.S. Yosemite
    Processer:2.8 GHz Intel Core 2 Duo
    Memory: 4 GB 667 MHz DDR2 SDRAM
    Graphics: ATI Radeon HD 2600 Pro 256 MB

    This works okay for elementary purposes such as web surfing (as long as there are no more than two or three windows open) and e-mail (the smart phones can just as easily do these), but it is taxed severely when trying to do HD video processing. When I bought my Mac, HD flash camcorders had not made an appearance yet, and MiniDV was the highest resolution for a recording format.

    The current lineup of iMacs and Mac Pros use use a motherboard with a front side bus of 1867 MHz, but the new motherboards use a bus almost twice that. I may consider getting another Mac, but if they don't upgrade them with the current generation of equipment this year, I'll keep what I have and see what alternatives are out there.
