■
DIMMs are populated starting from the outside (away from the CPU) and
working
toward the inside.
■
CPUs with only a single pair of DIMMs must have those DIMMs installed in that
CPU’s outside white DIMM slots (6 and 7).
■
Only DDR2 800 Mhz, 667Mhz, and 533Mhz DIMMs are supported.
■
Each pair of DIMMs must be identical (same manufacturer, size, and speed).
Note –
DDR2 DIMM names in Integrated LOM messages are displayed with the full
name, such as /SYS/MB/P0/D7.
4.1.2.2
DDR2 DIMM Fillers
DDR2 DIMM fillers are installed in all unoccupied DIMM sockets. All sockets must
be occupied by either a filler or a DDR2 DIMM. When DDR2 DIMMs are added,
remove the fillers. When DDR2 DIMM are removed, add extra fillers. Always place
fillers in empty sockets.
