I've noticed that with 4GB physical ram, I'm only see 3098000 MB on
the Dell 745, and 3107056MB on the IBM X60s.
I've tested with CONFIG_HIGHMEM4G=y, CONFIG_HIGHMEM64G=y,
CONFIG_X86_PAE=y, but nothing makes any difference.
Chipset limitation. It uses up most of the MMIO region above 3GB
preventing RAM from being mapped there, and doesn't support remapping
the covered RAM to above 4GB. Nothing the kernel can do about it.
