Windows Server only using 32 of 48 GB install memory
Server is running Server 2008 R2 Enterprise x64 and only using 32 of 48 gb of installed memory. What gives? Obviously if I was running Standard edition my problem would be pretty clear, but I'm not.
I actually figured this out myself. Turns out my Dell Poweredge was configured wrong in the BIOS. I went in and changed the Memory Operating Mode to Optimizer Mode and the Node Interleaving to Enabled. It was just an inkling I had. I now have full use of all 48 GB.
