5-5 Installing Memory
The motherboard supports up to 3 TB of Load Reduced (LRDIMM) or 1.5
TB or Registered (RDIMM). Memory modules should be DDR4 ECC 288-pin
2400/2133/1866/1600 MHz in 24 slots. Memory speed is dependent on the CPUs.
For best memory performance, install memory modules of the same type and same
speed. For the latest CPU/memory updates, refer to the Supermicro website.
Caution: Exercise care installing or removing DIMM modules to avoid damage.
Installing Memory Modules
Insert the desired number of DIMMs into the memory slots, starting with P1-DIMM 1A
1. Push the release tabs outwards on both ends of the DIMM slot to unlock it.
2. Align the key on the DIMM module with the receptive point on the slot.
3. Use two thumbs together to press on both ends of the module straight down
into the slot until the module snaps into place.
4. Press the release tabs to the lock positions to secure the DIMM module into
the slot. See Figure 5-2.
