Size 192GB 2X96GB

  • 192 GB capacity with two 96 GB modules for high-density server workloads
  • DDR5 6400 speed (PC5-51200) delivers rated throughput for the Supermicro X14SDW-42C-SP9F
  • Registered ECC architecture with CL52 latency corrects single-bit errors and offloads the memory controller
  • 1 V operation at 2Rx4 rank matches the board's exact voltage and timing requirements
  • 288-pin RDIMM form factor ensures correct physical and electrical fit in every supported slot

Server DDR5 ECC RDIMM Kit

This 192GB kit contains two 96GB DDR5 6400 registered ECC RDIMMs built for the Supermicro X14SDW-42C-SP9F motherboard. The modules run at 1.1V with CL52 latency and a 2Rx4 rank configuration. They are designed for servers that require registered memory with error correction.

Registered 2Rx4 Architecture

The single specification that decides fit is the registered 2Rx4 DDR5 RDIMM form factor at 1.1V. This motherboard only accepts 288-pin registered ECC modules with this exact rank and voltage; unbuffered UDIMMs or SODIMMs will not be recognised.

Full-Population Stability

Registered buffering offloads the memory controller so every slot runs fully populated at the rated 6400 speed. ECC corrects single-bit errors on the fly to prevent silent data corruption. Verify the board manual for approved DIMM population order before installation.

Questions about this item

Will the 6400 MT/s speed run at that rate on my Supermicro X14SDW-42C-SP9F?

The kit is spec-matched to the board's DDR5 6400 memory controller, so the modules will be recognised at their rated 6400 MT/s when installed in the correct slots.

Does the 288-pin RDIMM form factor fit the Supermicro X14SDW-42C-SP9F DIMM slots?

Yes, the 288-pin Registered DIMM is the exact form factor the motherboard requires; it is not a UDIMM or SODIMM and will seat in the standard DDR5 server slots.

What clearance does the 96 GB module need since it has no heat spreader?

Without a heat spreader the modules are low-profile, so they fit in tight server chassis and allow normal airflow from the system fans.
