SuperMicro DDR5 4800 UDIMM

This NEMIX RAM module provides 16 GB of DDR5 memory rated at 4800 MT/s with a CL40 latency and 1.10 V operating voltage. It is built as a 288-pin unbuffered non-ECC UDIMM using major OEM DRAM chips and carries the part number MD38400-618K1 for SuperMicro compatibility. The single-rank 1Rx8 design fits standard DDR5 desktop and workstation slots.

Suits SuperMicro workstations needing a single 16

Buyers whose systems require registered or ECC memory cannot use this unbuffered non-ECC module. Builders looking for capacities above 16 GB per slot or speeds beyond 4800 MT/s will need different modules. Anyone without a DDR5-compatible SuperMicro platform should verify their motherboard specification before purchasing.

4800 MT/s DDR5 speed rating

The PC5-38400 designation confirms the module runs at 4800 MT/s, which is the key specification that determines whether it matches the memory controller requirements of the target SuperMicro system. If the platform demands a different data rate this stick will not operate at its rated performance.

Questions about this item

Does my motherboard need a 288-pin DDR5 slot for this UDIMM?

Yes, this module uses the 288-pin DDR5 UDIMM form factor and requires a matching slot on a compatible Supermicro system.

Can I add this 1Rx8 module alongside existing 1Rx8 DDR5 sticks?

Yes, adding this 1Rx8 module next to other 1Rx8 DDR5 modules is supported on compatible Supermicro platforms that accept mixed ranks.

How do I confirm the memory runs at 4800 MT/s with CL40 after install?

Check the BIOS or an OS tool such as CPU-Z; it should report 4800 MT/s and CL40 timings at 1.10 V.
