2.5.2 Memory Configurations
You may install 16GB, 32GB, 64GB RDIMMs or 128GB, 256GB 3DS RDIMM into the DIMM
sockets using the memory configurations in this section.
• Refer to ASUS Server AVL for the updated list of compatible DIMMs.
• Always install DIMMs with the same CAS latency. For optimum compatibility, it is
recommended that you obtain memory modules from the same vendor.
2.5.3 Installing a DIMM
Make sure to unplug the power supply before adding or removing DIMMs or other system
components. Failure to do so may cause severe damage to both the motherboard and the
components.
1. Unlock a DIMM socket by pressing
the retaining clips outward.
2. Align a DIMM on the socket such that
the notch on the DIMM matches the
DIMM slot key on the socket.
A DIMM is keyed with a notch so that it fits in only one direction. To avoid damaging the
DIMM, DO NOT force a DIMM into a socket in the wrong direction.
