D3031 (RX200 S6)
Main memory
Features
– Single and dual and quad rank memory modules may be mixed.
– Install the memory module with the highest number of ranks into the slot with
the lowest number (e.g. modul typ 4GB 2Rx4 into slot DIMM1A and modul
typ 4GB 1Rx4 in slot DIMM2A).
– In the case of same number of ranks install the memory module with the
highest capacity into the slot with lowest number (e.g. 8GB 2Rx4 modules
(DIMM-1A) before 4GB 2Rx4 modules (DIMM-2A)).
– Mix of modules with different capacity is possible bank-wise (2x2) with Mirror
or Spare Mode.
– The assignment of the DIMM slots to the banks and channels is printed on
the system board.
3.2.2 Modes of operation
Possible population in the different modes:

Independent Channel Mode
– Allows population of all channels in any order. Related to the channels (A-F)
DIMM1 must be populated first.
– Works with DIMMs of different clock rates and applies the lowest clock rate.
– Works with UDIMMs as well as RDIMMs.
