Memory population information
Dual CPU (Start with
CPU1. CPU1 and CPU 2
population should
match)
Optimized (Independent channel)
population order
C1{1},C2{1},C1{2},C2{2},C1{3},C
2{3}…
Odd amount of DIMMs per CPU
allowed.
Mirroring population order
C1{1,2,3,4,5,6},C2{1,2,3,4,5,6}
Mirroring is supported with 6 DIMMs
per CPU.
Single rank sparing population order C1{1},C2{1},C1{2},C2{2},C1{3},C
2{3}…
Populate in this order, odd amount per
CPU allowed. Requires two ranks or
more per channel.
Multi rank spare population order
C1{1},C2{1},C1{2},C2{2},C1{3},C
2{3}…
Populate in this order, odd amount per
CPU allowed. Requires three ranks or
more per channel.
Fault resilient population order
C1{1,2,3,4,5,6},C2{1,2,3,4,5,6}
Supported with 6 DIMMs per CPU.
Removing a memory module
Prerequisites
1
Follow the safety guidelines listed in
2
Follow the procedure listed in
Before working inside your system
.
3
Remove the air shroud.
4
Remove the drive backplane.
WARNING:
Allow the memory modules to cool after you power off the system. Handle the memory modules by the card edges
and avoid touching the components or metallic contacts on the memory module.
CAUTION:
To ensure proper system cooling, memory module blanks must be installed in any memory socket that is not occupied.
Remove memory module blanks only if you intend to install memory modules in those sockets.
Steps
1
Locate the appropriate memory module socket.
2
Push the ejectors outward on both ends of the memory module socket to release the memory module from the socket.
3
Lift and remove the memory module from the system.
Figure 26. Removing a memory module
Next steps
1
Install the memory module.
2
If you are removing the memory module permanently, install a memory module blank. The procedure to install a memory module blank
is similar to that of the memory module.
