shouldnt this be 16gb?

thanks

no. Why do you think the address space should be that limited?

A 32-bit process typically has a virtual address space within the 2-gigabyte range 0x00000000 through 0x7FFFFFFF.
A 64-bit process on 64-bit Windows has a virtual address space within the 128-terabyte range 0x000'00000000 through 0x7FFF'FFFFFFFF.

I'm just trying to understand why PM says address space is 8gb when I have 16gb of ram....or is it measuring video card ram?

thanks

Read the article I posted. The term "address space" is not referring to your RAM capacity.

And it doesn't say 8 GB, it says 8 TB - 8 million MB, not 8 thousand. That's the minimum allowed DEC Alpha standard capacity.

It's essentially how many pointers can theoretically exist, regardless of your system's actual specs, if you're on a 64 bit computer.

Actually, no, it's rather the overall mappable location pointers can point to. They are literally analogous to home addresses. A street doesn't have to have contiguous addresses on the houses, but this "address space" limits how high of a number any house is allowed to have when choosing it.

PM says address space is 8gb

No it does not. As was pointed out earlier, you're not converting your units properly.
