Modes Of Operation - Fujitsu D3031 Technical Manual

Main memory
– Single and dual and quad rank memory modules may be mixed.
– Install the memory module with the hi g hest number of ranks into the s lot 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 di f ferent 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.

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.
