memory remapping needed?

[tommo123]

it's on by default in my bios and i'm guessing it's whats causing a small chunk of ram to disappear? e.g i have 16GB but 15.7 usable according to windows.

If anything it's enabling more to be used. Memory remapping is what lets you use the memory covered by the addresses some hardware devices require. Without that, you lose the ability to address that memory.

My father in law has an older MB that can recognize up to 8gig of ram. Without memory remapping enabled in the BIOS it can only see 4gig. Have you tried disabling to see what happens? If it doesn't work you can always re-enable it once you reboot.

true. just don't want to mess around if i don;t have to

do you have the integrated GPU enabled as it will take a piece of the memory for itself.

^ That. 15.7 seems an awful lot like IGP using 256MB. Aero +Glass, and whatever they're calling the stuff in Win 8, these days), your browser, and Flash can use 150-200MB, and 256MB has been a mobo default for a few years, now.
