Memory congurations
You may install 4 GB, 8 GB 16 GB, and 32 GB unbuffered DDR4 DIMMs into the DIMM
sockets.
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.
