Hi All,

I have a customer with two Vista 64 bits trying
to run software that explicitly states its does not
work with Vista, especially 64 bit Vista. Oh, what
a mess!

Question: her computers have 6 GB of memory.
If I change her over to XP 32 bit, being
that 32 bit OS's only can use 4 GB of memory,
what happens to the extra 2 GB of memory?
Does it just get ignored or do I get a BSOD?

Many thanks,
-T

It get ignored.

Why not make it a dual boot with Vista 64-bit and XP 32-bit.

Thank you!

Her two critical programs are a mess in Vista, especially 64 bit

XP will do everything she need correctly and twice as fast

Dual boot is a bit complicated for her

A 32 bit operating will ignore the extra 2 gig of RAM. You will likely see
something along the lines of 2.8 to 3.5 gig shown in Windows XP.

Change her to XP 5.2 64-bit

You could install VMWare virtual machine and install XP into the virtual
machine. That way, she gets her vista and all the rest of her apps using the
max memory and XP using whatever memory you give it. Both versions of
Windows running simultaneously (XP inside a vista window)

The 32 bit OS will ignore the extra 2GB. As Richard pointed out the 6GB will read
only between 2.5 and 3.2GB

It gets ignored, but it's not just 2GB that gets ignored; it's more
like 3GB.

Here's the scoop on it:

All 32-bit client versions of Windows (not just Vista/XP/7) have a 4GB
address space (64-bit versions can use much more). That's the
theoretical upper limit beyond which you can not go.

But you can't use the entire 4GB of address space. Even though you
have a 4GB address space, you can only use *around* 3.1GB of RAM.
That's because some of that space is used by hardware and is not
available to the operating system and applications. The amount you can
use varies, depending on what hardware you have installed, but can
range from as little as 2GB to as much as 3.5GB. It's usually around
3.1GB.

Note that the hardware is using the address *space*, not the actual
RAM itself. If you have a greater amount of RAM, the rest of the RAM
goes unused because there is no address space to map it to.

There is a performance hit with VM's. And she is luck if she
would crack 600 MB under XP. Plus VM's are more complicated.

Just so long as there is not BSOD. Thank you!
