We have a Dell T410 server using 4x2GB RDIMMs for a total of 8GB. I thought I would be able to replace 2 of those 2GB RDIMMs with 2x4GB RDIMMs to increase our total RAM from 8GB to 12GB.
However, I am very confused by how this works. According to the manual:
* Channel 0 is DIMM slots A4 and A1
* Channel 1 is DIMM slot A2
* Channel 2 is DIMM slot A3
* Memory modules of different sizes can be mixed within a memory channel (for example, 2-GB and 4-GB), but all populated channels must have identical configurations. This applies to only channel 0.
How can I mix my RDIMMs in this configuration? Is there a way to do this without having the system report a non-optimal configuration?
EDIT: Also, I'm only using the first memory bank since we're only using a single CPU right now.
