Two green DDR5 RDIMM modules without heat spreaders, 288-pin, 256GB kit

NEMIX RAM

NEMIX RAM 256GB (2x128GB) DDR5 6400 CL52 4Rx4 ECC RDIMM Supermicro X14SDW-40C-SP9F memory upgrade

SKU CH-VPMP-Z4D3Y

A 256 GB DDR5 registered ECC memory kit (2 × 128 GB) running at 6400 MT/s with CL52 latency and 1.1 V, validated for the Supermicro X14SDW-40C-SP9F motherboard

Size 256GB 2X128GB

  • 256 GB kit (2 × 128 GB) delivers full DDR5 6400 speed
  • CL52 latency at 1.10 V ensures rated throughput on every slot
  • 4Rx4 registered ECC architecture corrects single-bit errors to prevent silent data corruption
  • 288-pin RDIMM form factor matches Supermicro X14SDW-40C-SP9F population rules exactly
  • Lifetime replacement warranty with free US-based technical support included

Exact-match server upgrade

This 256GB kit comprises two 128GB DDR5 6400 RDIMMs built for the Supermicro X14SDW-40C-SP9F motherboard. Registered ECC architecture and 4Rx4 organisation match the board's memory-controller expectations so the full capacity is recognised at rated speed.

Capacity and headroom

Two 128GB modules deliver 256GB of registered ECC memory, allowing every supported slot to run fully populated while correcting single-bit errors on the fly. Systems that require more than 256GB or need unbuffered UDIMMs cannot use this kit.

DDR5 6400 CL52 1.1V spec

The modules operate at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V, the precise timing and voltage the X14SDW-40C-SP9F memory controller requires for stable operation at full population.

Points forts

Questions sur cet article

Will this DDR5 6400 kit run with my existing Supermicro X14SDW-40C-SP9F modules?

The kit is spec-matched to the X14SDW-40C-SP9F at DDR5 6400, CL52, 1.1V, 4Rx4 registered ECC. Populate remaining slots following the board's population rules so all channels run at the rated speed.

How can I confirm the kit is running at DDR5 6400 CL52 after install?

Check the BIOS memory info or OS tools such as dmidecode; they should show 6400 MT/s, CAS 52, 1.1 V and registered ECC status for both 128 GB modules.

What comes in the box and what else do I need?

The box contains the 256 GB (2×128 GB) DDR5 6400 CL52 4Rx4 ECC RDIMM kit only. No extra cables, brackets or software are required for installation.
