•
64 GB LRDIMMs that are DDP (Dual Die Package) LRDIMMs must not be mixed with 128 GB LRDIMMs that are TSV (Through Silicon
Via/3DS) LRDIMMs.
•
x4 and x8 DRAM based memory modules can be mixed.
•
Up to two RDIMMs can be populated per channel regardless of rank count.
•
Up to two LRDIMMs can be populated per channel regardless of rank count.
•
A maximum of two different ranked DIMMs can be populated in a channel regardless of rank count.
•
If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory modules.
•
Populate memory module sockets only if a processor is installed.
•
Populate all the sockets with white release tabs first, followed by the black release tabs.
•
When mixing memory modules with different capacities, populate the sockets with memory modules with the highest capacity first.
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.
•
Memory modules of different capacities can be mixed provided other memory population rules are followed.
For example, 8 GB and 16 GB memory modules can be mixed.
•
In a dual-processor configuration, the memory configuration for each processor must be identical.
For example, if you populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.
•
Mixing of more than two memory module capacities in a system is not supported.
•
Unbalanced memory configurations result in a performance loss so always populate memory channels identically with identical DIMMs
for best performance.
•
Populate six identical memory modules per processor (one DIMM per channel) at a time to maximize performance.
•
To ensure proper system cooling, memory module blanks must be installed in memory sockets that are not occupied.
Removing a memory module
Prerequisites
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.
1. Follow the safety guidelines listed in
.
2. Follow the procedure listed in
Before working inside your system
3.
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.
NOTE:
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.
