Missing 1 Gig of RAM!?!
on Aug 20, 2005 at 6:54:00 pm

I'm just getting my DIY running and I noticed that WinXP Pro only recognizes 3 GB of RAM under the "System Properties" window... The BIOS recognizes the 4 Gigs (reads: 4096 MB) I have installed on Asus P5WD2 Premium mobo.... Also the 2 pairs RAM installed in dual-channel mode.

What's going on here?

Abstract: BIOS DISPLAYS MEMORY SIZE WITH 4GB OR MORE


TEXT:

BIOS displays a smaller memory size with 4GB or more of memory
installed.

SYMPTOMS:

Whenever 4GB (or more) of memory is installed, the BIOS will
display the total size minus the amount of memory which is
being reserved for the PCI, I/O, and other resources.

PROBLEM ISOLATION AIDS:

- The system may be any of the following IBM e(logo)servers:

an xSeries 220, Type 8645, any Model.
an xSeries 330, Type 8654, any Model.

- The system is any of the following IBM Netfinity servers:

a Netfinity 8500R server, Type 8681, any Model.
a Netfinity 7000 M10 server, Type 8680, any Model.
a Netfinity 5600 server, Type 8664, any Model.
a Netfinity 5500 M20 server, Type 8662, any Model.

- The system may be any of the following IBM IntelliStations:

an IntelliStation M Pro, Type 6850, any Model.

- The system has the described symptom.

DETAILS:

Each PCI device is allowed to claim some amount of memory
resource. BIOS gathers the resource requirements of all the PCI
devices installed and reserves the memory for the PCI devices.

If the memory size is less than 4GB, BIOS will display the full
amount of memory installed in the system. For any memory amount
of 4GB or greater, POST may display less than 4GB of memory
depending on what resources have been reserved for PCI devices.
The amount of memory displayed will vary depending on the
system and configuration.

- The system may be any of the following IBM IntelliStations:

an IntelliStation M Pro, Type 6850, any Model.

- The system has the described symptom.

DETAILS:

When 4 GB or more of memory, physical or logical, is installed,
some memory is reserved for various system resources and is
unavailable to the operating system.

The amount of memory that is reserved for system resources
depends on the operating system, the configuration
of the server, and the configured PCI options.
