    I am seeing this message in System Information:

    Installed Memory (RAM): 8.00 GB (7.89 GB usable)

    OS is 64-bit Windows 7 Ultimate.

    Does anyone know why I can't use all my RAM?

    Thanks in advance for your input!

    I would take a shot in the dark that ~100MB is reserved for the Intel IGP. But still, that's only 1/64th of your total installed RAM... relax :)

    Good idea :)

    Yeah, I'm not really concerned, but I tried searching online and didn't turn up anything particularly informative.

    Thanks!

    No worries... assuming that's what it is, be thankful you don't have a new MacBook Pro. The latter takes away 384MB for it, even when based on the exact same 2720QM CPU.

    It's reserved for the IGP when you're on integrated or Optimus.
