Memory Usage On 64 bit machines
Posted on 2015-02-08
Suppose I have 12 Gigs of memory in a 64 bit PC.
When I run a 64 bit program, does it use the first 4 gig that is available to 32 bit programs, or the extra 8 gigs?
In other words, is having 12 gigs available of indirect benefit to 32 bit programs?
Is it first come, first served for the first 4 gigs?
Does windows dynamically switch memory usage of 64 bit programs, as 32 bit programs start?
