Hello, I'm trying to upgrade the Ram in a Poweredge R710 server.
It currently has 6 x 4GB sticks (3 sticks for each CPU, located in slots A1,2,3 and B1, 2, 3.
I need to upgrade this to 32GB of RAM to match another servers configuration. My original plan was to remove the 4GB sticks in slots A1 and B1, and replace them with 8GB sticks.
I did this, and the system boots, but it gives a message about invalid memory configuration. if I press F1, it still boots in to ESXi off the USB stick, and seems to work just fine. But I'd like to get rid of the error message on startup.
Do I have the sticks in the wrong slots for this configuration? I read and re-read the hardware manual, but im a little confused. it states:
"Memory modules of different sizes can be mixed within a memory channel (for example, 2-GB, 8-GB, and 4-GB), but all populated channels must have identical configurations"
So based on that, it seems like this should work, but i'm unsure if I'm missing something. Any suggestions?
