System 5130AD-T User's Manual

The C7Z270-PG supports up to 64 GB of Unbuffered (UDIMM) non-ECC DDR4 memory, up
to 3600MHz (OC) in four 288-pin memory slots. Populating these DIMM modules with a pair
of memory modules of the same type and same size will result in interleaved memory, which
will improve memory performance.
Notes:
Be sure to use memory modules of the same type, same speed, same frequency on the
same motherboard. Mixing of memory modules of different types and speeds is not allowed.
Due to memory allocation to system devices, the amount of memory that remains available
for operational use will be reduced when 4 GB of RAM is used. The reduction in memory
availability is disproportional. See the following table for details.
For Microsoft Windows users: Microsoft implemented a design change in the Windows XP with
Service Pack 2 (SP2) and Windows Vista. This change is specifi c to the behavior of Physical
Address Extension (PAE) mode which improves driver compatibility. For more information,

Memory Population Guidelines
When installing memory modules, the DIMM slots should be populated in the following order:
DIMMA1, DIMMB1, then DIMMA2, DIMMB2. Always use DDR4 DIMM modules of the same
size, type and speed. Mixed DIMM speeds can be installed. However, all DIMMs will run at
the speed of the slowest DIMM.
