IBM Power 750 Technical Overview And Introduction page 69

Number of DCMs
Three DCMs
Four DCMs
Each riser card in the system must be populated with at least one pair of DIMMs.
No memory CoD: The Power 750 and Power 760 systems do not support capacity on
demand (CoD) for memory.
Figure 2-9 shows the physical memory DIMM topology for Power 750 and Power 760
connected to one DCM.
