My client has a single processor PowerEdge T610.
It has 4 x 2GB DDR3-1066 dual ranked RDIMM modules installed in channels A2 A5 A3 and A6.
We wish to add 2 x 4GB modules.
I bought 2 x 4GB DDr3-1066 RDIMM's.
When I add the new modules to channels A1 and A4 and start the server at the initial memory configuration step I get a warning message saying channels A1 and A4 are disabled in this mode.
Due to time constraints I was unable to reboot again to get the exact message.
I read the Dell paper "Installing and Upgrading DDR3 Memory" but still can't be sure what the problem is here.
I would appreciate any advice.
