Windows 7: Memtest and missing (PCI) memory addresses

Memtest and missing (PCI) memory addresses

If I place a single 4GB stick in my machine and run memtest, I see it's testing only 3.7GB. I assume this is the PCI memory map taking 0.3GB. Does this mean I'm not actually testing all the memory or am I missing something?

I really don't know the answer, but an assumption would be that it takes some memory to run the computer and the test.
