I have a Tyan K8WE (S2895) with 4 gigs of ram and a dual core opterons.

When the computer first starts the boot screens show all 4 GB of ram are
recongized, however once I'm into x64 the RAM shown on the System Properties
screen (and Task Manager performance) is only 2.75. How can I access the
rest of this RAM?

Thats strange, I know this happens on 32 Bit XP. Have you updated your BIOS?

Hmm, now I'm nervous how my installation of WinXP Pro X64 will
handle 4 GB, because I have ordered 2 GB more last week.

<http://www.gamepc.com/labs/view_content.asp?id=xpx64&page=3>
shows that x64 should be able to detect it.

Bios->NorthBridge: Memory Hole remapping by sofware -> ENABLED.

et voila: 4 GB.

Can't speak for the Tyan board (I avoid 'em) but on my Asus K8N-DL, 4 GB RAM
is present, and 4 GB is reported by x64 Edition.

Yeah - that's it -- the memory hole. Don't worry fellas... it supports 4 GB.
I changed the memory hole setting in BIOS to Hardware (although Software
probably works too). I think that the BIOS was reserving 1.25 gb for my
nearly empty PCI slots.

Easy fix.

Okay. Mine is a NCCH-DL board (also from Asus).

Windows XP x64 Edition supports up to 128GB ; on top of the 4GB space, there
is some Hypertransport configuation space, which yields in some cases 3.9 GB
on boards populated with 4GB.
Note that the software hole remapping might be an issue if you do DMA IOMMU
calls above 4GB ; you'll feel like an Intel user...

I sure hope that my motherboard supports 4 GB "out of the box"
because I can't find a memory hole setting in BIOS.
