Dimension 4600 - using 4GB maximum - how

I'm about to install 4GB into a Dell Dimension 4600 running a Northwood 3.4GHZ CPU.

The memory consists of two Dell 1GB PC3200U-30330 DDR 400MHZ CL3 Non-EEC memory chips and two Micron 1GB PC3200U-30330 DDR 400MHZ CL3 Non-EEC 64x8.memory chips

My understanding is old machines like the Dimension 4600 will not necessarily recognize all 4GB unless I install the right operating system. I believe it's something to do with 32-bit and 64-bit systems which I'm completely unfamiliar with.

Can anyone tell me what operating system I need to install/what I need to do to have the machine use and recognize all 4GB.

I have copies of Windows XP Home, Windows XP Professional and Windows 7 Ultimate that I can install on the 4600.

I thank you all for your help in advance.

I very much appreciate anything you can tell me.

Northwood don't have x86-64 so won't run 64bit window, so you cannot get all 4GB usable.

Do you know what the maximum amount is that the Northwood 3.4CHZ CPU will recognize in the Dimension 4600 and how I can maximize this amount?

I got exact dell as HTPC but with 2GB RAM. I am not getting it more RAM because I know it won't run 64 bit window. If you want me to guess how much RAM is used, I will say about 3GB.

Thanks for your help. I very much appreciate it. I decided just to install XP Professional and accept I'll just be using 3GB of memory.

Thanks again for taking the time to respond. I very much appreciate your help.
