  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank2Rx4
  • 128GB total capacity expands server memory headroom with two 64GB modules
  • DDR5 6400MHz speed delivers high data throughput for demanding workloads

  • 1V operating voltage reduces power draw per module
  • 2Rx4 dual-rank organisation increases memory density per DIMM

System-specific DDR5 ECC kit

This 128 GB kit contains two 64 GB registered DDR5 modules built for the Supermicro SYS-822GS-NB3RT. It targets server and workstation operators who need error-correcting memory validated for that platform.

Straightforward DIMM installation

The modules use the standard 288-pin RDIMM form factor and slot into the server’s memory channels without tools. The main risk is mixing ranks or speeds across channels, so follow the board manual’s population rules exactly.

128 GB registered capacity at 6400 MHz

Two dual-rank 64 GB sticks deliver 128 GB of ECC-protected memory running at CL52 and 1.1 V. This covers large virtualisation or database workloads; applications that exceed 128 GB will require additional kits and free DIMM slots.

Questions about this item

How can I verify the 128GB kit is running at 6400MHz with CL52 after installation?

Enter the server BIOS or UEFI and confirm the memory frequency shows 6400 MT/s and CAS latency reads 52; the modules operate at 1.1 V and are registered ECC RDIMMs.

What does the MR51200-924K2 kit contain and are extra parts required?

The box includes two 64 GB 288-pin DDR5 ECC RDIMMs; no additional components are needed for the Supermicro SYS-822GS-NB3RT.

Which capacity option should I choose for the SYS-822GS-NB3RT?

This 128 GB (2 x 64 GB) 2Rx4 kit matches the validated configuration for the Supermicro SYS-822GS-NB3RT.
