Server-Specific DDR5 Kit

This 512GB kit contains four 128GB DDR5-6400 RDIMMs built for the Supermicro X14SDW-64CM-SP9F motherboard. It targets administrators who need the exact rank, voltage and timing the board's memory controller expects for full-capacity operation.

DDR5 RDIMM Population Limits

The 288-pin Registered ECC modules use a 4Rx4 organisation that lets the memory controller drive every slot at the rated 6400 MT/s speed. Population rules and maximum supported capacity are defined by the motherboard manual, not by the modules themselves.

512GB Registered ECC Headroom

Four ranks per DIMM and on-die ECC protect large working sets from single-bit errors while the registered buffer keeps signal integrity at full load. Workloads that exceed the board's approved DIMM-per-channel limit or total capacity ceiling will require a different platform.

Perguntas sobre este artigo

Should I buy this 512 GB kit or look for smaller capacities?

This kit provides exactly 512 GB (4 × 128 GB) of DDR5-6400 ECC RDIMM memory. Choose it when your Supermicro X14SDW-64CM-SP9F motherboard requires the full 4Rx4 registered population at 1.1 V to reach maximum supported capacity.

What does the 6400 MT/s rating mean once the modules are installed?

The DDR5-6400 (PC5-51200) modules run at 6400 MT/s with CL52 latency at 1.1 V, delivering the peak bandwidth the X14SDW-64CM-SP9F memory controller expects when all four slots are populated with 4Rx4 registered DIMMs.

How does the 288-pin RDIMM interface limit what I can do with this kit?

The 288-pin registered ECC RDIMM form factor fits only DDR5 RDIMM slots that support 4Rx4 modules; it cannot be used in UDIMM, SODIMM or non-ECC slots, and the motherboard must approve this rank and voltage combination in its qualified vendor list.
