2.5 Memory Support and Installation
Note
: Check the Supermicro website for recommended memory modules.
Important:
Exercise extreme care when installing or removing DIMM modules to pre-
vent any possible damage.
Memory Support
The C9X299-PG300F motherboard supports up to 128GB of Non-ECC DDR4 memory with
speeds of up to 4000MHz (overclocked) in eight memory slots. Populating these DIMM slots
with memory modules of the same type and size will result in interleaved memory, which will
improve memory performance.

DIMM Installation
1. Insert the desired number of DIMMs into the
memory slots, starting with DIMMA1, DIMMB1,
DIMMC1, DIMMD1, then DIMMA2, DIMMB2,
DIMMC2, DIMMD2. For best performance,
please use the memory modules of the same
type and speed.
2. Push the release tabs outwards on both ends
of the DIMM slot to unlock it.
