HP DL585 G5 only shows 2 GB memory in system properties

Hi all,
I have a DL 585 G5 that only shows 2 GB of memory installed. This is 4 socket 4 core/per socket server with w2k std.
On the general tab of the system properties it is only showing 2 GB when it should be showing 4 GB.
In the memory slots I have 2 - 2gb sticks in slots 1 and 2 (outside first 2 slots) for each processor.

I have updated the bios to the latest version (7/09). I think I have the memeory sticks in the correct locations.

Not sure what else to try here.

Thanks Matt

Does it show the full 4GB while the server boots up? If that's the case, check http://www.microsoft.com/whdc/system/platform/server/PAE/PAEdrv.mspx for info about PAE and Windows.

The "bank order" seems to be important?

Memory Options
Minimum Memory Requirements

Two DIMMs must be installed in bank 1 on the processor memory board in slot two.

All DIMMs on a processor memory board must have the same part number.

NOTE: Processor memory boards in slots 1, 3, and 4 may be installed without memory.

Memory Population Guidelines

Supported configurations:

DIMMs on different processor memory boards can be of different sizes,
but DIMMs on the same processor memory board must be of the same size and have the same part number.
DIMMs must be installed on a processor memory board in pairs and in bank order.

Processor Memory Board Memory Banks
Slot Bank
1 - 2 Bank 1
3 - 4 Bank 2
5 - 6 Bank 3
7 - 8 Bank 4
