Memory Reporting Issue?

I have four new ESX 3.5 hosts (Dell R900's). I created a new cluster, added the hosts. Each host has 128 GB of RAM. Now VC is reporting that 51% of that RAM is used on each host. BUT, I only have two VMs in the cluster. Anyone seen this?

Thanks,

Jeff

I solved this with a call to support. I needed to disable the following in advanced settings on each host:

VMkernel.Boot.force36BitMTRRMask

The modification requires a reboot of the host.

Once the change was made and the host rebooted, I was able to access all 128 GB of RAM
