Speed 4800MHz

  • 768 GB total capacity from eight 96 GB modules for maximum memory density
  • DDR5 4800 speed with CL40 latency delivers rated bandwidth for server workloads
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation at 2Rx4 rank matches the Supermicro H13SRH memory controller exactly
  • 288-pin RDIMM form factor ensures physical and electrical compatibility with the target motherboard

768GB DDR5 RDIMM kit for Supermicro H13SRH

This kit provides 768GB of DDR5 4800 memory in eight 96GB registered ECC modules. It is built for the Supermicro H13SRH motherboard and matches the board's required 288-pin RDIMM form factor. The CL40 timing and 1.1V operation meet the memory controller's exact specifications.

Registered ECC design with 2Rx4 organisation

Each module uses a 2Rx4 rank layout and registered architecture to offload the memory controller, allowing all slots to run fully populated at rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption. The modules have no heat spreader and operate at the standard 1.10V DDR5 voltage.

Replaces smaller or slower DDR5 RDIMM sets

This kit upgrades systems currently running lower-capacity DDR5 4800 registered ECC modules or partial population. The jump is worthwhile when workloads need the full 768GB capacity and the motherboard's population rules support eight 96GB 2Rx4 DIMMs. Buyers needing UDIMM, SODIMM or non-ECC memory cannot use this kit.

Questions about this item

Does the DDR5-4800 (PC5-38400) standard cap the kit at 4800 MT/s on the Supermicro H13SRH?

Yes, the 8x96GB modules are rated DDR5-4800 (PC5-38400) and will run at that speed when the board's memory controller is populated per its population rules.

What physical slot and form factor must the Supermicro H13SRH provide for these 288-pin RDIMMs?

The motherboard needs eight 288-pin DDR5 RDIMM slots; the kit will not fit UDIMM, SODIMM or any other slot type.

In what order should the eight 2Rx4 RDIMMs be seated to avoid a no-post condition?

Follow the H13SRH manual's exact DIMM population sequence for eight registered modules; skipping the prescribed slot order is the most common install error.
