Memory Problem

[Clayton]

I have a ASUS P5B-PLUS Motherboard and have installed 2 x 2GB DDR-2 800MHz
modules in it and the BIOS only showed as having 3GB installed so I updated
to the latest BIOS version and remapped the memory in the BIOS and now the
BIOS is showing all 4GB, but after installing Windows 7 32-Bit it shows in
system properties as 4GB installed but only 2GB usable.

The motherboard is a couple of years old now and was wonder if installing
2GB modules is the problem, I'll try to get a hold of 4 x 1GB modules and
see what shows up

 

[Curious]

Do you have a matched pair of 2GB modules?

 

[Clayton]

Yes I do

Do you have a matched pair of 2GB modules?

 

[Clayton]

Ok, I have just put in 4 x 1GB modules and still reporting 2GB usable

Update:
Have turned remap off in the BIOS and now Windows 7 reports 4 GB installed
and 2.94 GB usable
Now the BIOS reports available system memory 3008 MB

That'd be what's expected. In the 32-bit version of Vista, your actual
available memory space will be between 2.7-3.3GB, as the 32-bit version only
has 4GB of addresses available and some of these reserved for the hardware.
How much is reserved depends on the system and its configuration, the memory
gets whatever the difference is. Installation of SP1 will allow it to report
that there is 4GB installed, but the usable memory figure will always be
around 3GB.
