I just built a new quad proc r900 Dell with 128 GB RAM for our vm environment. Upon bootup it shows that it's using 66GB RAM. This host does not even have any virtual machines running on it?? Any clues on what would cause this issue? Any help or ideas would be much appreciated!
Thanks,
What does 'esxtop' -> hit 'm' key for memory tell you?

I'm having the exact same issue. Today performed a fresh install of ESX 3.5 Update 1 on a Dell r900, 4 quad, 128 Gig of ram. On first boot the system is using 50% of memory.
Nothing interesting under mem stats other than "Memory Usage" and "Memory Consumed are at 50%". Everything else looks normal.
Was there any update to this issue?

Yes. By default you have to enable support on a host that has more than 64GB RAM. To change the following setting on the host under the Configuration Tab. Advanced Settings > VMKernel > Boot > DESELECT "VMkernel.Boot.force.36BitMTRRMask" and reboot your host and you will be good to go.
Hope this helps.
That did the trick. Thanks for the quick reply!
