Exact-match DDR5 RDIMM kit

This 128GB kit contains four 32GB DDR5 6400 Registered ECC modules built to the Supermicro X14SDV-42C-SP3F memory controller specification. It delivers the precise rank, voltage and timing the board expects so the system recognises the full capacity at rated speed.

DDR5 RDIMM population limits

Registered architecture offloads the memory controller allowing every slot to run fully populated at full capacity while ECC corrects single-bit errors on the fly. The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function.

128GB capacity headroom

Four ranks per module provide dense capacity for virtualization and database workloads that benefit from large memory footprints. Workloads needing more than 128GB or a different DIMM type will require a platform change.

Questions about this item

Should I pick this 128 GB kit or a smaller capacity for the Supermicro X14SDV-42C-SP3F?

The kit delivers 128 GB across four 32 GB modules, matching the board's DDR5 6400 registered ECC requirements; verify the manual's maximum supported capacity and slot population rules before deciding.

What does DDR5 6400 (PC5-51200) actually give me once installed in this server?

The modules run at 6400 MT/s with CL52 latency at 1.10 V, providing the rated bandwidth and error correction the motherboard expects when all four slots are populated with registered DIMMs.

Does the 288-pin RDIMM interface limit speed or capacity on the X14SDV-42C-SP3F?

The 288-pin registered form factor is exactly what this motherboard requires; it enables full-capacity operation across all slots at the specified DDR5 6400 speed without downclocking.
