I have the following problem/situation:
I own an Intel D945GNT L main board, using a Intel Pentium D945 processor, and running Windows 7 Pro 64 bits.
The mainboard has the latest BIOS version.
I use an external PCIExpress video card (NVIDIA GeForce6200 TurboCache), so no memory sharing for video.
I was using 2 GB RAM (2x1) and both BIOS & Win7 showed RAM=2Gb.
Yesterday I added 2 Gb. BIOS shows all 4Gb. Win7 shows: Installed 4Gb, 3.25 usable.
I have checked and discovered BIOS doesn't have the remapping option.
Verified that the Maximum memory box is unchecked in Boot Advanced Option's in MSCONFIG.
So, the situation is a CHIPSET problem?
INTEL says the motherboard supports up to 4Gb ram.
(I also tested installing 5Gb ram...both BIOS and win 7 show 5Gb installed, but only 3.25 usable).
I read something confusing in INTEL's site regarding my mainboard:

Integrator's Note
It is possible to install four 2048 MB (2 GB) modules for a total of 8 GB of system memory, however, only 4 GB of address space is available.
What does that mean??? it is a waste of resources??? it will only use 4gb?? or 8?
Will it be possible of arranging anything to get the full 4Gb operational???
Despite the mainboard is a discontinued model…can we expect a bios update with the remapping feature???
Is PAE (physical address extension) related to this??? I can’t clearly see what that means.
Please, I need your help and advice to get the full amount of RAM usable!
Thanks in advance.
