IBM Power 8 31FC ... 256 GB DDR4 CDIMM
31FC is the IBM identifier for a 256 GB DDR4 CDIMM, FRU part number 00VK243. It applies to 8247-42L, 8286-42A.
31FC identifies a 256 GB DDR4 CDIMM on IBM Power 8 systems, carried in IBM parts documentation under FRU part number 00VK243. IBM lists it against 8247-42L, 8286-42A.
Power 8 memory is not generic server memory. The CDIMM parts in particular are custom IBM modules with the buffer on the DIMM itself, which is why a DDR4 CDIMM cannot be substituted with an off-the-shelf DDR4 module of the same capacity.
Before you order against this number, read the VPD on the machine itself. Power 8 systems were built over several years and a machine that left the factory with one part may well have been serviced since.
