Owners Manual
• Populate all the sockets with white release tabs rst, followed by the black release tabs.
• When mixing memory modules with dierent capacities, populate the sockets with memory modules with the highest capacity rst. For
example, if you want to mix 8 GB and 16 GB memory modules, populate 16 GB memory modules in the sockets with white release tabs
and 8 GB memory modules in the sockets with black release tabs.
• The memory conguration for each processor should be identical. For example, if you populate socket A1 for processor 1, then populate
socket B1 for processor 2, and so on.
• Memory modules of dierent capacities can be mixed provided other memory population rules are followed (for example, 8 GB and 16
GB memory modules can be mixed).
• Mixing of more than two memory module capacities in a system is not supported.
• Populate six memory modules per processor (one DIMM per channel) at a time to maximize performance.
Mode-specic guidelines
Six memory channels are allocated to each processor. The congurations allowed depend on the memory mode selected.
Removing a memory module
Follow the below procedure for removing a DIMM module:
Prerequisites
1 Follow the safety guidelines listed in Safety instructions.
2 Follow the procedure listed in Before working inside your system.
3 If applicable, remove the air shroud.
WARNING
: Allow the memory modules to cool after you power o 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.
