When considering the memory configuration of your server, you should observe the following: 

■

Only 1 memory riser on any CPU is required to boot the system. 

■

Memory risers on non-installed CPUs will not work.

■

Memory risers do not need to be populated in pairs 

■

If not installing all risers, for optimal CPU air flow, even numbered risers should be installed 
first. 

■

Each memory riser has two memory buffers, each of which controls two DDR channels with 
up to 3 DIMMs per channel.

■

For optimal performance DIMMs should be spread evenly across all CPUs and DDR channels

■

DIMM1 of a channel should be installed first (blue socket), then DIMM2 (white socket), then 
DIMM3 (black socket)

When populating DIMMs on the memory riser cards, observe the population order shown in the following 
tables:

■

Population order for 4 CPUs and 8 risers: see 

■

Population order for 2 CPUs and 4 risers: see
