PowerEdge T440 memory upgrade
Have a single CPU T440 with 96gb, 6x16gb. Looking to add more memory without adding another processor (so I don't violate server core licensing).
I see there are 10 DIMM slots allocated to Socket 1 which would provide a theoretical maximum of 160gb if all 10 slots are populated. However the service manual states to populate six slots for best performance. If I add two or four more DIMMs to get to 128gb or 160gb will there be a performance penalty for running in those memory configurations, or should I just stay at 96gb?

Hello thanks for choosing Dell and welcome to our community.

We have to have infomration on your current memory specification such as the size (GB), and how many you have plugged in.

It is in the first sentence of my post I have Six (6) 16gb Modules for a total of 96gb currently.

With the 6 dimms installed it is all going across a single memory channel, when you add more it then goes to the second channel, which will drop performance. Now if the server isn't under too heavy of a load then this may be acceptable to you.

Do you know how much of a performance drop it would be?

Not specifically, as there are too many variables. What I would suggest is testing it under both configurations and see what works best for your configuration.
