Server memory kit for Supermicro H13DSH

This 256GB kit contains sixteen 16GB DDR5 Registered ECC RDIMMs built for the Supermicro H13DSH motherboard. Each module runs at 6400MHz with CL52 latency at 1.1V in a 1Rx8 layout. The registered design lets the memory controller drive all sixteen slots at full capacity.

Suited for administrators populating every slot

Buyers who need a smaller capacity or a different form factor such as UDIMM or SODIMM should look elsewhere. Systems that cannot accept registered ECC DDR5 RDIMMs will not work with this kit.

288-pin DDR5 RDIMM form factor

The modules use the 288-pin registered DDR5 layout required by the H13DSH. A motherboard that does not support this exact pinout and registered signalling will not recognise the memory.

Questions about this item

Will the 6400 MT/s speed actually run at 6400 MT/s on a Supermicro H13DSH?

The kit is spec-matched to the H13DSH so the memory controller recognises the 1Rx8 rank, 1.10 V voltage and CL52 timing, allowing all 16 modules to operate at the rated DDR5-6400 data rate.

What does the PC5-51200 label cap in real use?

PC5-51200 denotes the peak transfer bandwidth of the DDR5-6400 modules; actual throughput is limited by the H13DSH memory controller and the number of populated channels.

Do these 288-pin RDIMMs fit the H13DSH DIMM slots without adapters?

Yes, the 288-pin registered RDIMM form factor is exactly what the H13DSH requires; no UDIMM or SODIMM adapters are needed.
