16 GB DDR5 ECC RDIMM for Supermicro servers

This 16 GB DDR5 4800 MHz registered DIMM adds ECC-protected capacity to compatible Supermicro GPU SuperServer systems. It is built for IT professionals who need reliable memory upgrades in mission-critical server and workstation environments.

Tool-free DIMM slot installation

The module seats in a standard 288-pin DDR5 RDIMM slot and typically takes only minutes to install. Always consult the system owner's manual for the correct population order and any BIOS settings required for registered ECC memory.

DDR5 4800 bandwidth ceiling and registered latency

The PC5-38400 interface caps peak throughput at the DDR5 4800 data rate, while CL40 latency and the registered buffer add command overhead. Workloads that demand higher frequencies or lower latency will hit this module's electrical limits.

Questions about this item

How do I confirm the 16GB DDR5 4800 module is running at CL40 1.1V after installing it in my SuperMicro server?

Enter the system BIOS or UEFI and open the memory information screen; it should show the module operating at 4800 MT/s with a CAS latency of 40 and a voltage of 1.10 V.

What comes in the box and do I need any extra brackets or cables for the 288-pin RDIMM?

The package contains one 16 GB 288-pin DDR5 ECC RDIMM; no additional brackets, cables or heat spreaders are required for installation.

Should I choose the 1Rx8 16GB version or look for a different rank or capacity for the SYS-821GE-TNHR?

The 1Rx8 16 GB registered ECC module is the specified configuration for the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT platforms.
