64 GB DDR5 ECC RDIMM Kit

This 64 GB kit contains four 16 GB DDR5 modules rated at 4800 MT/s with CL40 latency. Each stick is a 1.1 V registered DIMM with on-die ECC and a 1Rx8 organisation. The memory is validated for SuperMicro IoT SuperServer SYS-211SE-31DS, SYS-211SE-31AS and X31SEED-SF motherboards. It targets administrators who need guaranteed compatibility in those specific platforms.

Suits SuperMicro 211SE and X31SEED builds

The kit fits servers and workstations that require registered ECC DDR5 on the listed SuperMicro boards. It is not intended for consumer desktops, laptops or motherboards that accept only unbuffered non-ECC memory. Buyers who need higher capacities per module or different speeds should look at other qualified configurations.

Registered ECC DDR5 at 4800 MT/s

The registered ECC design with 1Rx8 architecture is the single specification that determines whether this kit will operate in the target SuperMicro systems. Only platforms qualified for PC5-38400 RDIMMs at 1.1 V can use this memory.

Questions about this item

Does the 64GB kit contain four 16GB modules or do I need to buy additional sticks?

The kit includes four 16GB DDR5 RDIMM modules for a total of 64GB; no extra sticks are required.

Should I choose the 1Rx8 CL40 1.10V version or a different rank and latency for my SuperMicro 211SE-31DS?

The 1Rx8 CL40 1.10V specification matches the memory qualified for the SuperMicro 211SE-31DS and 31AS platforms.

What does the 4800MHz rating mean once the memory is installed in the server?

The modules run at DDR5 4800 speed with CAS latency 40 at 1.10V, delivering the rated PC5-38400 bandwidth in compatible SuperMicro systems.
