Exact-match server upgrade

This 64 GB kit contains four 16 GB DDR5 RDIMM modules built for the Supermicro H13SSH-E motherboard. Registered ECC architecture offloads the memory controller and corrects single-bit errors so fully populated slots run at rated speed without silent data corruption. The kit arrives new and ready for installation.

DDR5 4800 CL40 1.1 V specification

Speed is DDR5 4800 (PC5-38400) with CAS latency CL40 at 1.1 V. Modules use a 1Rx8 rank layout on 288-pin registered DIMMs, matching the board's required voltage, timing and rank organisation exactly. Major-brand Samsung Micron or Hynix ICs are used throughout.

Thermals and power in normal use

Bare modules operate at the standard DDR5 1.1 V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable during sustained workloads. No active cooling or extra voltage is required.

Questions about this item

Will the DDR5-4800 speed run at its rated frequency on the Supermicro H13SSH-E?

The kit is an exact-match upgrade validated for the H13SSH-E, so the memory controller will recognise the 4800 MT/s rating and operate each module at that speed when all four slots are populated.

What does the 288-pin RDIMM form factor require from the motherboard?

The board must accept 288-pin registered DIMMs; UDIMM or SODIMM slots are physically incompatible and will not accept these modules.

How much clearance do the 16 GB modules need inside the chassis?

Each module is a standard-height 288-pin RDIMM without a heat spreader, so it fits in any server chassis that accommodates full-height DDR5 RDIMMs.
