Hello,
This settings has no assumption on the amount of RAM in your system. You do
not need 3 gig or ram in your system to change this settings
This simply changes the allocation of address space from 2 gig system and 2
gig user to 1 gig system and 3 gig user.
This also will have the effect of reducing the amount system resources(
desktop heap, paged pool, System PTEs, etc) since allocation of address
space is now down to one gig.
Thanks,
Darrell Gorter[MSFT]
