The memory remap setting just moves the PCI reserved space out of the lower
4 GB so you can use 4 GB RAM. But it still has to appear SOMEWHERE in the
memory space. Most current 64 bit motherboards have an 8 GB address
space. It looks like the memory remap setting moves your PCI reserved
space to just beyond 4 GB. Some move it to the TOP of the 8 GB space,
so you wouldn't see this issue until you install 8 GB RAM.
There is nothing you can do about this. Any OS would see the exact same
memory map. This is not a Windows problem, and there is no solution. Put
in 2 more GB (8 GB) and you will have 7374 MB of useable RAM.
Until motherboards have an address space of 256 GB or more and remap the PCI
address space WAY UP HIGH, this will continue to be a problem.
