Lots of ram, windows xp 64 and 32bit emulation

Hi!
Do any off you know if windows xp64 loads in the upper parts of memory?
Considering buying 4GB more of memory if windows xp64 places itself above the 4GB mark. Hoping to get more memory freed for 32bit apps, as I guess these will have to stay in the first 0-4GB of memory

Anyone know?

Don't worry about any of that stuff. Applications live in an private virtual address space, and it can be located anywhere in physical memory.

Wont the use of MMU to correct the addressing above 4GB slow down the app badly?

No, that makes no difference.

You could have 8GBs installed and it wouldn't make a difference in 32-bit apps. They can use any memory they want... it doesn't have to be below the first 2GB... it can be the last 2GB if that's where Windows decides to put it. If it slowed the app down badly, then there wouldn't be any point in allowing 32-bit programs to run on a 64-bit OS.
