Chapter 1. General description 17
Table 1-7 gives the maximum and minimum memory configurations for Power 750 and
Power 760 with different number of DCMs installed.
Table 1-7 Maximum and minimum memory configurations of the Power 750 and Power 760
Table 1-8 details the memory features available in the Power 750 and Power 760.
Table 1-8 Summary of memory features available on Power 750 and Power 760
A memory riser card can have two, four, six, or eight DIMMs ordered by one, two, three, or
four memory features. All the memory features can be the same in the riser card, or two
different size memory features can be used in the same riser card. If using two different sized
memory features, valid configurations are as follows:
򐂰 Four DIMMs total: one memory feature plus one different memory feature
򐂰 Six DIMMs total: two memory features plus one different memory feature
򐂰 Eight DIMMs total: two memory features plus two different memory features
Invalid configurations using more than one memory size feature are as follows:
򐂰 More than two sizes of memory features. For example: 8 GB plus 16 GB plus 32 GB on
one riser.
򐂰 Three of one memory features plus one of another memory feature. Use two sets of two
features instead if installing eight DIMMs.

Additional memory configuration rules:
򐂰 Different system memory feature codes may be mixed on each of the two memory riser
cards servicing each DCM.
򐂰 Each riser card must have at least one memory feature code (two identical DIMMs).
