Re: Why It’s A Perfect Time to Upgrade Your RAM If You Have DDR2

If you're using a 32-bit operating system (which most people are), then there's a strong likelihood that 3GB is the most that you can upgrade to.

I recently upgraded to a whole new computer system and discovered that the fourth GB is completely invisible to the system. Doing a little more research revealed that this last gigabyte is where video cards and other BIOS gets mapped in. Even if you have the RAM, these other devices get the first shot at the memory locations in that fourth gig.

The best you can do is get 3.25 or 3.5 GB of usable RAM, but that involves going into your BIOS settings to see if there are any options to move things around.

The solution is to run a 64-bit OS, but that might lead to compatibility issues with some applications.
