Exact DDR5-6400 RDIMM Kit
This 256GB kit contains 16 registered ECC modules rated at 6400 MT/s with CL52 timing and 1.10V operation. It is built for the Supermicro H14DSG-OD motherboard and matches the 288-pin RDIMM form factor that platform requires. System integrators and IT teams needing a validated, full-population upgrade use this exact configuration.
Population Rules Limit Capacity
The motherboard dictates how many DIMM slots can be filled and in which order, so the full 256GB is only available when the board supports 16 modules. Registered buffering allows every slot to run at rated speed, but the manual defines the maximum supported capacity per channel. Buyers who need a different total capacity or fewer modules must select a kit that matches their board's approved population table.
1Rx8 Rank Determines Compatibility
Each module uses a single-rank 1Rx8 organisation, which the memory controller expects for correct timing and signal integrity. A dual-rank or different rank layout would change electrical loading and can prevent the system from posting or running at DDR5-6400. Verify that your server's memory-qualified vendor list approves 1Rx8 registered DIMMs before ordering.

Questions about this item
Should I pick the 16-module 256 GB kit or a smaller capacity for my Supermicro H14DSG-OD?
The 16 x 16 GB kit fills every DDR5 RDIMM slot on the H14DSG-OD, delivering the full 256 GB at the rated 6400 MT/s with CL52 and 1.1 V. Smaller kits leave slots empty and reduce total capacity.
What does the 6400 MT/s rating actually deliver once the modules are installed in the server?
The board's memory controller will run the registered ECC DDR5 DIMMs at 6400 MT/s (PC5-51200) with CL52 latency at 1.1 V, giving the full rated bandwidth across all 16 slots.
How does the 288-pin RDIMM interface and registered ECC design affect real-world limits?
The 288-pin registered DDR5 form factor buffers each command, allowing all 16 ranks to operate at 6400 MT/s without signal degradation, while on-die ECC corrects single-bit errors before they reach the OS.
