Speed 4800MHz

  • 384 GB total capacity from eight 48 GB modules enables large-scale virtualization and in-memory databases
  • DDR5-4800 CL40 at 1.1 V delivers rated bandwidth with standard server voltage
  • Registered ECC RDIMM architecture offloads the memory controller and corrects single-bit errors for enterprise stability
  • 2Rx8 dual-rank organisation maximises density across all populated slots on the Supermicro H13SRH
  • 288-pin DDR5 form factor matches the motherboard's required slot type and population rules

System-specific DDR5 RDIMM kit

This 384 GB kit contains eight 48 GB DDR5-4800 registered ECC modules built for the Supermicro H13SRH motherboard. Each 288-pin RDIMM runs at 1.1 V with CL40 latency and a 2Rx8 organisation. The registered design lets every slot run fully populated at the rated 4800 MT/s speed.

Suited for max-capacity server builds

Ideal for administrators expanding a Supermicro H13SRH to its full 384 GB limit with matched, registered ECC memory. Not suitable for workstations or consumer boards that accept only unbuffered UDIMMs, nor for systems limited to lower-density modules or slower DDR5 speeds.

Deciding spec: registered ECC RDIMM

The modules are 288-pin DDR5 RDIMMs with on-die ECC and a registered buffer, the exact form factor the H13SRH memory controller requires. If your platform calls for UDIMM, SODIMM or non-ECC memory this kit will not fit or function.

Questions about this item

Should I pick the 384GB 8x48GB kit or a different capacity for my Supermicro H13SRH?

The 384GB kit uses eight 48GB modules to fill all eight slots on the H13SRH. Choose this kit when you need the maximum supported capacity; select a smaller kit only if your workload does not require the full 384GB.

What does the DDR5-4800 CL40 rating deliver once installed in the server?

The modules run at 4800 MT/s with a CAS latency of 40 cycles at 1.10V. The registered buffer lets all eight slots operate at that rated speed without downclocking, while ECC corrects single-bit errors in real time.

How does the 288-pin RDIMM interface limit performance on the H13SRH?

The 288-pin RDIMM form factor is the only type the H13SRH accepts. It caps the kit to the DDR5-4800 (PC5-38400) data rate and CL40 timing the board's memory controller specifies.
