Speed 4800MHz

  • 768 GB total capacity from six 128 GB modules for maximum server density
  • DDR5-4800 speed with CL40 latency runs at the board's rated frequency
  • Registered ECC design offloads the controller and corrects single-bit errors automatically
  • 1 V operation matches the Supermicro H13SRH memory controller specification exactly
  • 288-pin RDIMM form factor fits the required server slots without adapters

Exact-match DDR5 upgrade kit

This 768GB kit contains six 128GB DDR5-4800 RDIMMs built to the Supermicro H13SRH motherboard's exact rank, voltage, and timing requirements. Each module is a 2Rx4 registered ECC DIMM operating at 1.1V with CL40 latency. The 288-pin form factor matches the board's memory slots precisely.

Registered ECC population limits

Registered (buffered) architecture offloads the memory controller so every slot can run fully populated at the rated 4800MHz speed. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. Server memory support varies by model, so consult your system manual for approved DIMM population order and maximum supported capacities before installation.

Replaces mixed or partial memory sets

This kit replaces incomplete or mismatched DIMM configurations that force the memory controller to run at reduced speeds or capacities. The jump is worth it when your workload demands the full 768GB at native DDR5-4800 throughput with hardware error correction. It is not for systems that require UDIMM or SODIMM form factors, or for boards that do not support 2Rx4 registered modules at this density.

Questions about this item

Should I choose the 768GB kit with six 128GB modules or a smaller capacity for my Supermicro H13SRH?

The kit provides 768GB total across six 128GB RDIMMs. Populate all six slots only if your motherboard manual confirms support for that capacity and population order; otherwise install fewer modules following the approved sequence.

What does the DDR5-4800 CL40 rating mean for real-world server throughput?

The modules run at 4800 MT/s with a CAS latency of 40 cycles. Registered buffering and ECC maintain stability at that speed across all populated slots, delivering the bandwidth the memory controller expects without downclocking.

How does the 288-pin RDIMM interface and PC5-38400 standard limit performance?

The 288-pin RDIMM form factor matches the H13SRH slots exactly. The PC5-38400 designation caps the data rate at 4800 MT/s, so the kit cannot exceed that transfer rate even if the platform supports faster DDR5 speeds.
