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

  • Best Answer:

    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!
