16GB DDR5 6400 ECC RDIMM

This 16GB DDR5 6400MHz module is a Registered ECC RDIMM built for the Supermicro H14DSG-O-CPU motherboard. It delivers 1Rx8 organisation at 1.1V with CL52 timing, matching the exact rank, voltage and latency the platform expects. System administrators upgrading that specific server board will find it recognised at full capacity and rated speed.

Registered ECC DDR5 limits

The 288-pin Registered form factor is required by this board; UDIMM or SODIMM modules will not fit or function. Registered architecture offloads the memory controller so every slot can run fully populated at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption. Buyers needing unbuffered memory or non-ECC operation cannot use this module.

CL52 1Rx8 1.1V specification

The decisive specification is the CL52 1Rx8 1.1V profile; the memory controller will only initialise at full speed when rank, voltage and timing align exactly. Verify your system manual for supported capacities and approved DIMM population order before purchase, as server memory rules vary by model.

Questions about this item

Should I pick the 16GB DDR5-6400 CL52 1Rx8 registered ECC module or a different capacity for my Supermicro H14DSG-O-CPU?

This exact-match upgrade is a single 16GB DDR5-6400 (PC5-51200) registered ECC RDIMM at 1.1V CL52 1Rx8. Check your motherboard manual for supported capacities and the required DIMM population order before deciding whether to add one module or fill multiple slots.

Will the DDR5-6400 rating actually run at 6400 MT/s once installed in the H14DSG-O-CPU?

The module is spec-matched to the board's memory controller with the precise rank, voltage and timing it expects, so it is recognised at full capacity and runs at its rated DDR5-6400 speed when populated according to the motherboard's rules.

What does the 288-pin registered ECC RDIMM interface cap in practice?

The 288-pin RDIMM form factor with registered (buffered) architecture lets every slot run fully populated at full capacity while ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.
