84.0 GB (32.0 GB usable) Windows Server 2008 R2 64 bit Enterprise W/Enterprise license.

From all I've read, an Enterprise Version of 2k8 server should allow up to 2 TB of ram.

The standard server is limited to 32GB.

Why is my 2k8R2 64 Enterprise only allowing 32GB?

The Motherboard allows 196GB of RAM. The OS shows 84 so it know it has been installed.

I verified the Key is Enterprise. I re-added the key. Nothing seems to allows me to use the RAM I have installed. 

Anyone have a Registry switch or other adjustment that will make this use all the installed RAM?

Thanks,

Robert
