DIMM Population Rules and Guidelines for the Sun
Blade X6275 M2 Server module
■
Only symmetric memory configurations resulting in 12 DIMMs per blade or 24 DIMMs per
blade are supported. Supported configurations:
■
Three DIMMs per CPU
■
Six DIMMs per CPU
Note –
Memory bandwidth (speed) drops to 1066 MHz when the DIMM slots are fully
populated (even when using 1333 MHz DIMMs).
■
Both CPUs on each node must be populated identically and must have exactly the same
memory configuration.
■
DIMM slot population order:
■
First set to populate: D5/D3/D1
■
Second set to populate: D4/D2/D0
■
Do not populate any DIMM socket next to an empty processor socket.
