Memory Support
The X11DPH-T has 2TB of Registered DIMM (RDIMM), Load Reduced DIMM (LRDIMM), 3D
LRDIMM, Non-Volatile DIMM (NV-DIMM) ECC DDR4-2933/2666/2400/2133 memory modules
in 16 slots. The black DIMM slots are reserved for future NVDIMM support.
Note: 2933 MHz memory is supported by the 82xx/62xx/52xx platform only. Only Platinum-
level and Gold-level processors support Intel Optane
(DCPMM).
Installing Memory
Begin by removing power from the system as described in Section 3.1 and removing the
cover as described in Section 3.2.
1. Starting with DIMMA1, push the release tabs outwards on both ends of the DIMM slot to
unlock it.
2. Align the key of the DIMM with the receptive point on the memory slot and with your
thumbs on both ends of the module, press it straight down into the slot until the module
snaps into place.
3. Press the release tabs to the locked position to secure the DIMM module into the slot.
Repeat for other DIMM slots as needed in the following order:
4. Insert DIMMs into the slots in the following order: DIMMA1, DIMMB1, DIMMC1,
DIMMD1, DIMME1, DIMMF1, DIMMA2, and DIMMD2. Use memory modules of the
same type and speed.
5. To remove a DIMM, unlock the release tabs then pull the DIMM from the memory slot.
Caution: Exercise extreme caution when installing or removing memory modules to prevent
any possible damage to the DIMMs or slots.
