Server memory kit for Supermicro H13DSH

This 128GB kit contains two 64GB DDR5 RDIMM modules built for the Supermicro H13DSH motherboard. It targets administrators who need registered ECC memory that the platform recognises at full capacity without manual tuning. The 2Rx4 organisation and 1.10V operation match the board's native memory-controller expectations.

DDR5-4800 speed and registered architecture

The modules run at 4800 MT/s (PC5-38400) with CL40 latency, the highest JEDEC-standard rate this platform supports natively. Registered buffering lets every slot stay populated at rated speed, while on-die ECC corrects single-bit errors before they reach the OS. Mixing ranks or voltages would break this stability.

2Rx4 registered ECC RDIMM form factor

The 288-pin RDIMM package with 2Rx4 rank layout is the single specification that determines compatibility. UDIMM, SODIMM or single-rank modules will not be accepted by the H13DSH memory controller. Verify the motherboard manual for approved population order before installation.

Questions about this item

Should I pick the 128 GB kit or a different capacity for my Supermicro H13DSH?

The kit supplies 128 GB as two 64 GB modules, matching the exact rank, voltage and timing the H13DSH memory controller expects for full-speed operation.

What does the DDR5-4800 rating mean once the modules are installed in the server?

The modules run at 4800 MT/s with CL40 latency at 1.10 V, delivering the PC5-38400 bandwidth the platform specifies when all slots are populated.

How does the 288-pin RDIMM interface limit what I can install?

The 288-pin Registered DIMM form factor is required by the H13DSH; UDIMM or SODIMM modules will not fit or function in this board.
