Memory population information
NOTE:
Odd number of
DIMMs will result in
unbalanced memory
configurations, which
in turn will result in
performance loss. It is
recommended to
populate all memory
channels identically
with identical DIMMs
for best performance.
•
Optimizer population order is not
traditional for 8 and 14 DIMM
installations of dual processor.
– For 8 DIMMs: A1, A2, A4, A5,
B1, B2, B4, B5
– For 14 DIMMs: A1, A2, A4, A5,
A7, A8, A9, A10, B1, B2, B3, B4,
B5, B6
Mirroring population order
A{1, 2, 3, 4, 5, 6}, B{1, 2, 3, 4, 5,
6}
Mirroring is supported with 6 DIMM
slots per processor.
Single rank sparing population order A{1}, B{1}, A{2}, B{2}, A{3},
B{3}...
Populate in this order, odd amount per
processor allowed. Requires two ranks
or more per channel.
Multi rank sparing population order
A{1}, B{1}, A{2}, B{2}, A{3},
B{3}...
Populate in this order, odd amount per
processor allowed. Requires three
ranks or more per channel.
Removing a memory module
Prerequisites
1
Follow the safety guidelines listed in
a
Follow the procedure listed in
Before working inside your system
.
2
.
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.
CAUTION:
Handle each memory module only by the card edges, ensuring not to touch the middle of the memory
module or metallic contacts.
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.
