– For single-processor systems, sockets A1 to A4 are available.
– In
Optimizer Mode
, the DRAM controllers operate independently in the 64-bit mode and provide optimized memory performance.

•
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.
•
Mixing of more than two memory module capacities in a system is not supported.
•
Unbalanced memory configurations will result in a performance loss so always populate memory channels identically with identical
DIMMs for best performance.
•
To ensure proper system cooling, memory module blanks must be installed in memory sockets that are not occupied.
Removing a memory module
Prerequisites
1
Follow the safety guidelines listed in
2
Follow the procedure listed in
Before working inside your system
.
3
.
WARNING:
The memory modules are hot to touch for some time after the system has been powered down. Allow the memory
modules to cool before handling them. Handle the memory modules by the card edges and avoid touching the components or
metallic contacts on the memory module.
Steps
1
Locate the appropriate memory module socket.
2
To release the memory module from the socket, simultaneously press the ejectors on both ends of the 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.
3
Lift the memory module away from the system.
