I believe you need a 64 bit OS to recognize all the RAM

Yes, you require a 64Bit operating system to fully address all 4GB of system memory.

You need a 64-bit OS for the cpu to be able to address more than 3.5gb of any memory. This includes memory on video cards and even sound cards. Little known fact is that's why Nvidia did 640 and 768 on their cards this generation. 2gb ram + 2x 768/640 vram = memory usable on 32-bit operating systems

It slammed Assassin's Creed's head onto the curb then stomped its head into that curb until it was nothing but a bloody pulp. This card is one bad mo-fo. It'll backhand your sister and degrade your mom, but they will still love it and want to date it because it is just that good. I love this card so much that I burned my tongue trying to french kiss it, and I still keep trying.

I thought the specific amount of memory on the G80 cards was to utilize the 384 bit memory bus. Source: techPowerUp Quote:

If you have 32-bit OS and you have a Dual core Processor than windows splits it up to for each core. Remember a high ram video card is also added so if you have 256MB video card than You will end up having 3.75GB's etc etc.
You can always try editing /PAE in boot.ini but it's not always supported by your hardware and it never worked for me. However I got 3Gb's of ram so ...

2GB for each core? where'd you get that? i don't care how many cores you got, if you have a 32-bit OS, 3.5GB is your MAX
