  • 512 GB total capacity from four 128 GB modules maximises server memory density
  • DDR5-6400 speed with CL52 latency delivers rated throughput for the platform
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 1 V operation at 4Rx4 rank matches the motherboard's electrical requirements exactly
  • Validated for the Supermicro X14SDW-72C-SP9F to ensure full-slot recognition at rated speed

Exact-match DDR5 server kit

This 512 GB kit contains four 128 GB DDR5 RDIMMs rated at 6400 MT/s (PC5-51200) with CL52 latency and 1.1 V operation. Each module is a 4Rx4 registered ECC DIMM built on major-brand DRAM and validated for the Supermicro X14SDW-72C-SP9F motherboard.

Suits Supermicro X14SDW-72C-SP9F builds

System integrators and IT teams populating every slot on this specific Supermicro board get full-capacity recognition and rated speed without manual tuning. Builders using consumer boards, UDIMM-only platforms, or systems that do not support registered ECC memory should select a different kit.

Install like standard RDIMMs

Insert the 288-pin modules into the slots specified by the motherboard manual, observing the recommended population order for four DIMMs. The most common issue is skipping the manual's slot sequence, which can prevent the system from booting or recognising the full 512 GB capacity.

Perguntas sobre este artigo

What motherboard must I already have for this 512GB DDR5 6400 kit to be recognised at full capacity?

The kit is validated for the Supermicro X14SDW-72C-SP9F motherboard running DDR5 6400 PC5-51200, so that board is required for the guaranteed fit.

Will these 4Rx4 registered ECC RDIMMs work if I keep older DDR5 modules in the remaining slots?

Mixing ranks or registered with unbuffered DIMMs is not supported; the board expects identical 4Rx4 registered ECC modules in every populated slot for stable operation.

How can I confirm the 1.1V CL52 modules are running at the rated 6400 speed after installation?

Check the BIOS memory information or a tool such as dmidecode — it should report DDR5 6400, CL52, 1.1 V and 512 GB total across the four slots.
