Why should it be mapped outside ? It is just somewhere you need hands and feet twice to calc the power of two...LOL
I was referring to reduced RAM availability on some 4Gb machines running an x64 OS because of the need to map video card memory into memory space. I'd understood that theoretically under x64 the video card memory can be mapped into some other range, meaning that all your RAM can remain available. Certainly that's how it looks on my machine.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
