SKU CH-JMW9-256ZE

A 64GB (2x32GB) DDR5-5600 CL46 2Rx8 ECC Registered RDIMM kit validated for the Supermicro X14SDW-40C-SP9F motherboard

  • Capacity64GB (2 x 32GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 5600 (PC5 44800)
  • CAS LatencyCL46
  • Voltage1.10V
  • ECCYes

Size 64GB 2X32GB

  • 64 GB kit (2 × 32 GB) gives full-capacity upgrade
  • DDR5-5600 PC5-44800 speed matches the board's rated frequency
  • Registered ECC RDIMM with 2Rx8 rank offloads the memory controller for stable full-population operation
  • 10 V CL46 timing meets the exact voltage and latency the controller expects
  • 288-pin form factor verified for Supermicro X14SDW-40C-SP9F motherboard

Exact-match server upgrade

This 64GB kit contains two 32GB DDR5-5600 Registered ECC RDIMMs built for the Supermicro X14SDW-40C-SP9F motherboard. The modules run at 1.1V with CL46 timing and a 2Rx8 organisation, matching the board's memory controller requirements for full-capacity recognition and rated-speed operation.

Installation and common issues

The 288-pin RDIMM form factor fits only Registered DIMM slots; it will not work in UDIMM or SODIMM sockets. Populate the slots in the order specified by the Supermicro manual, because incorrect population order is the most frequent reason a server fails to boot or reports reduced capacity.

Who this suits and who it does not

This kit suits administrators upgrading a Supermicro X14SDW-40C-SP9F platform that requires Registered ECC memory at DDR5-5600. It does not suit builders who need unbuffered UDIMMs, non-ECC modules, a different DDR generation, or a capacity or rank configuration not validated for this specific motherboard.

Questions about this item

How can I confirm the 64GB kit is running at DDR5-5600 CL46 after installation?

Check the BIOS or a tool such as CPU-Z; the memory should report 5600 MT/s, CL46 timings, 1.10 V and 2Rx8 registered ECC operation.

What exactly ships in the box and is anything else required?

The package contains two 32 GB 288-pin DDR5 RDIMMs for a total of 64 GB; no cables, brackets or additional parts are included or needed.

Why choose this 64 GB (2×32 GB) DDR5-5600 CL46 kit over other capacities?

It matches the Supermicro X14SDW-40C-SP9F memory controller specifications — 5600 MT/s, 1.10 V, CL46, 2Rx8 registered ECC — ensuring full-speed recognition and stability.
