3.1.2 Memory
The aTCA-6200 supports DDR3-1600 RDIMM with eight DIMM sockets (A to D and E to H) up to
128GBytes. Socket A to D are controlled by integrated memory controller in CPU1 as well as socket
E/F/G/H are controlled by integrated memory controller in CPU2. There are 3 memory channels from
CPU1 for socket A/B/C/D while socket C/D share the same memory channel. The design logic also
applies to socket E/F/G/H and socket G/H share the same memory channel.
Memory configuration changes are only permitted to be performed at the factory. Failure to
comply with the above may result in damage to your board or improper operation.
