how does the Windows 7 physical memory limit work?

post #1 of 4
Thread Starter 
Please help a newbie, this will be my first build...I have bought a number of items for it already, including 16gb ram, GTX 580 with 3gb, and Windows 7 home premium. Win 7 home premium is limited to 16gb physical memory according to http://msdn.microsoft.com/en-us/libr...78(VS.85).aspx

Does that 16gb limit include the VRAM?

If so,

(a) will the pc basically have 13gb of usable memory, but otherwise have no problems (my original thought was to have a ramdisk, I guess I still would but smaller),

OR

(b) will some sort of problems crop up because I'll have 19gb physical memory, counting the VRAM, vs the 16gb limit? If (b) is true, I may have to try to resell the Home Premium and get Pro instead.

Thanks in advance to anyone who might help.

VRAM should have no effect.


Really though, overkill on the RAM.

You will have 16gb's usable, not 19 not 13, 16

VRAM is for like texture filters, AA and all those settings for games
