DFI Lanparty NF4 Ultra D, 4GB and Vista Ultimate X32 = only 3GB ram!

Hi,

I've got a DFI Lanparty NF4 Ultra-D mainboard with 4x Kingston HyperX 1GB
modules. So it's 4GB.
This is the case:

With PCI MMIO disabled in the bios, the bios and Vista detect around 3.2GB
RAM
With PCI MMIO enabled in the bios, the bios detects 4GB and Vista detects
3GB (3070MB).

Vista X32 should support 4GB, the mainboard does support 4GB.

How do I get my 1GB? I didn't buy that extra 2GB dual channel kit for just
1GB of extra RAM

Of course your motherboard will read a complete 4Gb because it a direct
detection of hardware. Like XP, Vista x32 "supports" 4gb but it will only
show a certain amount because it holds a certain amount for other purposes
tied to the OS. The only time you will see a complete "4GB" is if you use x64.

"All editions of Windows Vista 64-bit provide increased memory support
beyond the standard 4 gigabytes (GB) available with 32-bit editions. Refer
to
the specific edition of Windows Vista 64-bit to determine maximum memory
capacity."

While your statement is nice and all...read his post again. He is using
32-bit, not 64-bit. 32 bit Vista still has a 4GB limitation and will not show
a complete 4GBs within the OS.

The only other thing that I see missing is if he has shared RAM for video?
If he has 1GB shared to video there's the missing RAM Sounds pretty wierd
to me unless he has the matched pair that isn't matched, in the wrong slots,
But it should be showing at least 4MB from the POST screen.
