The BIOS you say?  Then you have an issue with how the BIOS
is setting up the memory controller registers.  Sometimes
the OS can overcome those, but many times they represent
a greater issue with how the BIOS-chipset limits access.

Even though the memory controller is on the AMD processor,
the mainboard can still have trace/setup issues.  A lot of
early AMD64 platforms from various, "cheap" OEMs totally
screwed up various 40-bit/1TiB AMD addressing support.

That setting may vary.
