NEMIX RAM DDR5 6400 256GB 16x16GB ECC RDIMM CL52 1.1V Supermicro H14DSG-OD

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.
