We were told (by sales) that installing the HPC pack will increase the memory the OS can see.  I'm still seeing "(32.0GB usable)" in the control panel.  Can anyone that has worked with HPC verify this.  I've looked around MSDN and our licensing and it appears the OS itself is different.

I've been reading about it. I don't see anything specific that mentiones it increases the memory available to the O/S. That is a feature of the specific O/S you hae installed on your server.

I did find this regarding how much menory it can address:

Q.  How much memory does Windows HPC Server 2008 R2 Suite support?

A.  Windows HPC Server 2008 R2 Suite supports 128 GB of memory.

It came from this link:

The Windows Server 2008 R2 HPC Edition operating system supports up to 128 gigs of ram. This is not a configurable option.

The HPC Pack 2008 R2 software supports the additional memory available when run on an Enterprise of Datacenter edition operating system.

Yes, it supports additinal memory on Ent or Datacenter, that does not mean it creates it... Virtial memory.

I don't see anything definative here.
