Mobo only reading 1 channel of memory

[cb417]

Hey guys, I have just finished my first build and noticed that under system properties my computer is only showing 1.75 GB of Ram. The problem is I have 4 gigs installed. I have a biostar a785g3 motherboard and a-data 1333mhz ddr3 ram. Could this be a problem in the BIOS? If so, I have never worked with the bios before and would need some direction. Thanks for any help in advance.

Is your operating system is 64bit?

If you answered yes:
Search for an option for Memory Remapping in your bios.

If you answered no:
Get a 64bit OS.

If you answered I don't know:
Write dxdiag.exe in the search bar when you click on the start icon.
On the first page, in System information. Look for Operation system, it should tell you Windows Vista/7 32/64 bit.

I have windows XP 32 bit now but plan on getting 7 in the future. What other options do I have besides getting a new $100 OS?
