Exact-Match Server Upgrade

This 128GB kit contains two 64GB DDR5 RDIMMs rated at 6400MHz PC5-51200 with CL52 latency and 1.1V operation. The 2Rx4 registered ECC modules are built to the precise rank, voltage, and timing the Supermicro H13DSH memory controller expects for full-capacity recognition at rated speed.

Build Integration Requirements

The 288-pin registered RDIMM form factor matches the slots this motherboard requires — not UDIMM or SODIMM — and the kit is spec-matched to the board's population rules. Registered architecture offloads the memory controller so every populated slot runs at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption.

Sustained Workload Behavior

Enterprise-grade registered buffering maintains stability when all channels remain fully populated under continuous load, and on-die ECC protects data integrity across extended operations. The 1.1V baseline keeps power draw consistent during long-running server tasks, while the CL52 timing delivers predictable latency without thermal throttling concerns.

Questions about this item

Will the 1.1 V modules stay cool enough when the server runs 24/7?

The kit operates at the standard DDR5 1.1 V with no heat spreader, so airflow through the chassis is the only cooling path. Ensure the Supermicro H13DSH fan profile keeps DIMM slots within spec during sustained loads.

What motherboard slot and population rules must I follow for this 2Rx4 RDIMM kit?

Install the two 64 GB RDIMMs in the slots specified by the Supermicro H13DSH manual for a 2 DIMM per channel configuration. The board requires 288‑pin registered ECC modules and will not accept UDIMM or SODIMM form factors.

Does the Supermicro H13DSH need a specific BIOS version or CPU to recognise 128 GB of DDR5‑6400 ECC memory?

The kit is validated for the Supermicro H13DSH motherboard. Consult the board manual for supported CPU families, maximum capacity per slot, and any BIOS revision required to run the 2Rx4 modules at 6400 MT/s.
