Memory configurations
You may install 2 GB, 4 GB, 8GB and 16 GB unbuffered and non-ECC DDR4 DIMMs into the
DIMM sockets.
• For Intel ® Core™ X-series (4-core) Processors, you may install varying memory sizes
in Channel C and Channel D. The system maps the total size of the lower-sized
channel for the dual-channel configuration. Any excess memory from the higher-sized
channel is then mapped for single-channel operation.
• For Intel ® Core™ X-series (6-core above) Processors, you may install varying memory
sizes in Channel A, Channel B, Channel C, and Channel D. The system maps the
total size of the lower-sized channel for the quad-channel configuration. 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 efficient memory cooling system to support a full
memory load (8 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.
