  • 384 GB total capacity from four 96 GB modules for maximum server density
  • DDR5 4800 MHz speed with CL40 latency matching controller timing exactly
  • Registered ECC RDIMM architecture corrects single-bit errors and offloads the memory controller
  • 1 V operating voltage and 2Rx4 rank organisation meet Supermicro H13SSH specifications
  • 288-pin DDR5 RDIMM form factor ensures physical and electrical compatibility with the motherboard

Capacity and Compatibility

This 384GB kit contains four 96GB DDR5 RDIMM modules built for the Supermicro H13SSH motherboard. It delivers registered ECC memory in a 288-pin form factor that matches the board's population rules and required voltage.

Sustained Operation

Registered buffering reduces electrical load on the memory controller so all four slots run at the rated 4800MHz speed without throttling under continuous server workloads. On-die ECC corrects single-bit errors in real time to prevent silent data corruption during long-running tasks.

Critical Specification

The modules use a 2Rx4 rank structure with CL40 latency at 1.1V, the exact combination the H13SSH memory controller expects for full-capacity recognition. Systems requiring UDIMM, SODIMM or a different rank configuration will not accept this kit.

Questions about this item

How much heat does this 1.10 V DDR5 kit generate when the H13SSH runs fully populated 24/7?

Each 96 GB RDIMM operates at 1.10 V without a heat spreader; the registered design reduces electrical load on the memory controller, so total power draw stays within standard DDR5-4800 limits for a 384 GB configuration.

What must the H13SSH already provide for this 288-pin RDIMM kit to function?

The board needs four DDR5 RDIMM slots wired for registered ECC memory, a BIOS that supports 2Rx4 96 GB modules, and a memory controller rated for PC5-38400 at CL40.

Will the registered ECC design of this kit work with older unbuffered UDIMMs still installed in other slots?

No — registered RDIMMs and unbuffered UDIMMs cannot be mixed on the same platform; the H13SSH requires registered modules in every populated slot for correct operation.
