Vista - VPC 2007 maximum RAM

Hello,

currently I use a PC with 2 GB RAM and Windows 2000 as the host OS.
Sometimes I get the problem that it lacks needed RAM to start another VM.

I'd like to buy a new and faster PC with 4 GB RAM and Windows XP 32-bit.
XP can handle 3 GB or a bit more. Can VPC handle more than 2 GB (total)?

Why I ask: I know that VPC runs all VMs in a single process. A process
under Windows XP normally cannot allocate more than 2 GB of RAM, even if
more real RAM is available. But VPC may be different since its used
memory does not appear in the task manager's process list.

Thanks in advance,
Markus

Hello Markus,

You might consider using a 64-bit OS as the host instead so that you can have and use more than 3.2 GB of RAM with. VPC will only run a 32-bit OS VM, so it will never use more than 3.2 GB per VM if it is available from the host.

Hope this helps,
Shawn

GB in Windows 7 Beta 32 bit in a VM.

I have Vista 64 as the host and 8 GB RAM.

Yep, which is (pretty much) the maximum amount of RAM that a 32-bit OS can
use...
Which is the same thing - 3712 / 1024 = 3.62
Me too...

"With SP1, Windows Vista will report the amount of system memory
installed rather than report the amount of system memory available to
the OS. Therefore 32-bit systems equipped with 4GB of RAM will report
all 4BG in many places throughout the OS, such as the System Control
Panel. However, this behavior is dependent on having a compatible
BIOS, so not all users may notice this change", Microsoft revealed.

Probably the same for Windows 7.

It is.

host OS to get around extra cost.

Original question:
Given a PC with 4 GB RAM + Windows XP 32-bit host OS + VPC 2007.
XP can handle 3 GB or a bit more.
Can VPC handle more than 2 GB (total sum of all VMs)?

Is there anyone who tried this out?

Yes, VPC can handle more than 2GB. Each VM can have 3.7GB assigned to
it if is available on the the host system. VPC can handle over 7GB
for VMs on an 8GB x64 system.
Yes, I have.
