How much RAM can I use with this motherboard?

Question

I am building a new Intel-based computer. It will be using an Asus P5E LGA 775 X38 Motherboard.

The Motherboard's RAM standard is up to 8GB of DDR2 1200.

In the past, I have heard that 32 bit operating systems and processors cant use RAM sticks larger than 1GB. Is this still true? In my new computer, I plan on using Windows Vista Ultimate 32 bit. My processor is an Intel Quad Core Q6600.

So my question is if I can use 8GB of RAM with a 32-bit Operating System, or am I limited to 4GB? Thanks for anyone who contributes.

Answer 1

32 bit supports up to 4GB ( XP = 3GB max I think)

64 Bit supports up to 128GB

Answer 2

32 Bit O/S can ONLY use about 3.5GB ram and no more

64 Bit O/S can use 8GB ram and more  

Answer 3

32Bit is limited to 4GB but sometimes the OS only detects 3GB. With 64Bit you can go over 8GB even 32GB.

Answer 4

32bit Windows can only address 3.5GB of RAM even though 32bit computers can, theoretically, address 4GB.
