Chapter 1
You may install varying memory sizes in Channel A and Channel B. The system maps the
total size of the lower-sized channel for the dual-channel conguration. Any excess memory
from the higher-sized channel is then mapped for single-channel operation.
 The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value.
 For system stability, use a more efcient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.
 Always install the DIMMS with the same CAS Latency. For an optimum compatibility,
we recommend that you install memory modules of the same version or data code
(D/C) from the same vendor. Check with the vendor to get the correct memory
modules.
Memory configurations
You may install 2 GB, 4 GB, 8 GB, and 16 GB unbuffered and non-ECC DDR4 DIMMs into
the DIMM sockets.
