Server can't identify all the memory installed
Hello,
We have a Dell PowerEdge R420 which had 32 GB of Ram installed.
We have increase the ammount of Ram to 64GB but when cheking in the system information it states that only 32GB is usable.
How do we increase the capacity the server can use?

There's a switch that can be set up in Boot.INI to enable the extra memory. /PAE though I don't remember off the top.
did you add 16GB of ram in each processors' memory slots or did you stick the ram in one cpu's slots?
Honestly, I would be surprised if this was it, so are these OEM memory? Did you upgrade the memory? Are there any memory related error messages when you boot up?
