TIS Posted December 2, 2011 Report post Posted December 2, 2011 Hello, we have r610 server with 12 memory sticks per 4 GB each. Now we would like to upgrade memory, we wont to keep 6 sticks per 4 GB and 6 sticks per 8GB, or 6 sticks per 4 GB and 6 sticks per 16GB. We would like to verify will it work? Will speed drop down?
