See FIGURE 10-1. The memory sockets are colored black or white to indicate which slots are paired http://marc.info/?l=sun-managers&m=99563191704098&w=2 by matching colors. 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). See FIGURE 10-1. Only DDR2 800 Mhz, 667Mhz, and 533Mhz DIMMs are supported. Each pair of DIMMs must be identical (same https://docs.oracle.com/cd/E19469-01/819-4363-12/dimms_x4540.html manufacturer, size, and speed).

In addition, a DIMM should be replaced whenever more than 24 Correctable Errors (CEs) originate in 24 hours from a single DIMM and no other DIMM is showing further CEs. If more than one DIMM has experienced multiple CEs, other possible causes of CEs have to be ruled out by a qualified Sun Support specialist before replacing any DIMMs. Retain copies of the logs showing the memor
