Targeted 64 GB DDR4 kit for SuperMicro MBD-C9Z490-PG

This 64 GB kit contains four 16 GB DDR4 2933 MHz UDIMMs built for the SuperMicro MBD-C9Z490-PG motherboard. It delivers non-ECC unbuffered memory at CL21 latency and 1.2 V. The modules use major OEM chips and carry the MD23400-618K4 part number for verified compatibility.

Verify board slots and CPU support before ordering

Confirm the motherboard has four free 288-pin DDR4 slots and that the installed processor supports 2933 MHz non-ECC unbuffered memory at 1.2 V. The kit is single-rank 1Rx8; check the manual for any population rules or maximum per-slot limits. No heat spreaders are fitted, so ensure adequate airflow around the DIMMs.

Fits standard DDR4 UDIMM slots

The four modules populate all slots on the MBD-C9Z490-PG, delivering 64 GB total without mixing capacities. Standard 288-pin DDR4 UDIMM form factor requires no special mounting hardware. Buyers needing ECC, registered modules or speeds beyond 2933 MHz should look elsewhere.

Questions about this item

What does the 64GB kit contain and is anything else required?

The kit includes four 16GB DDR4 2933MHz CL21 1.2V 288-pin UDIMM modules. No extra parts are needed for installation in a compatible SuperMicro MBD-C9Z490-PG system.

How do I choose between the available versions or capacities of this memory?

This part number MD23400-618K4 is a single 64GB kit of four 16GB modules. Select it when the board requires 64GB of non-ECC unbuffered DDR4 at 2933MHz.

What does the 2933MHz rating mean once the modules are installed?

The system will run the memory at DDR4 2933 (PC4-23400) with CL21 latency at 1.20V, provided the SuperMicro MBD-C9Z490-PG motherboard supports that speed.
