Are you basically saying that on a 32 bit O/S if you have 3 gig of RAM and a 1 gig vid card you are using the 32 bit limit?
indeed.
even then with that setup... windows would show about 2.75gb of useable Ram.. 0.25gb of it will "vanish" or be "unuseable" by the normal operating system programs due to being used for other things...
Heres some basic math.. for those with any amount of ram installed while using windows 32bit be it xp/vista/7/8
32 Limit - Vram - 0.25gb reserved = Total Ram useable.
4gb - 1gb video card - 0.25gb = 2.75gb of useable ram
4gb - 1gb video card - 1gb video card (sli/crossfire) - 0.25gb = 1.75gb Ram (Problematic, making the machine below minimum requirements for most modern games)
4gb - 3gb video card - 0.25gb = 0.75gb of ram <~ TOTAL FAILURE ALA Counter Productive Means
4gb - 2gb video card - 2gb video card (sli/crossfire) - 0.25gb = -0.25gb <~ Windows LOLs at you and BSODs before being able to start.
