Supermicro C7Z270-PG Motherboard User’s Manual
The C7Z270-PG supports up to 64GB 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 re-
duced 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 Win-
dows Vista. This change is specific to the behavior of Physical
Address Extension (PAE) mode which improves driver compat-
ibility. For more information, please read the following article at
