Speed 5600MHz

  • 768GB total capacity across eight 96GB modules for maximum server memory density
  • DDR5 5600 speed with CL46 latency delivers rated performance on Supermicro H13SRH
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1V operating voltage matches the motherboard's memory controller specification exactly
  • 288-pin RDIMM form factor ensures physical and electrical compatibility with the target board

768GB DDR5 ECC RDIMM Kit

This 768GB kit contains eight 96GB DDR5 5600 registered ECC RDIMMs built for the Supermicro H13SRH motherboard. Each module runs at 1.1V with CL46 timing and a 2Rx4 organisation. The registered design lets the memory controller address every slot when the board is fully populated.

DDR5 5600 Registered Limits

DDR5 5600 (PC5-44800) sets the maximum data rate this kit will reach on the H13SRH platform. Registered DIMMs add one clock cycle of buffering, so the controller sees a stable load across all eight slots. ECC corrects single-bit errors on the fly but cannot repair multi-bit failures. The 288-pin form factor fits only DDR5 RDIMM sockets; it will not seat in UDIMM or SODIMM slots.

Upgrade From Smaller RDIMM Sets

Replacing a partial or lower-capacity RDIMM set with this eight-module kit fills every supported slot on the H13SRH at the board's rated 5600 speed. The jump is worth it when workloads need the full 768GB address space and the registered architecture to keep all channels stable. Systems that cannot accept 96GB dual-rank modules or that require UDIMMs cannot use this kit.

Questions about this item

Should I buy the 8-module 768GB kit or a smaller capacity for the Supermicro H13SRH?

The 8×96GB kit fills all channels on the H13SRH at the rated 5600 speed, while smaller kits leave slots empty and may not reach full bandwidth.

What does the 5600 speed mean once the modules are installed in the server?

The memory controller will run the kit at DDR5-5600 with CL46 timings at 1.10V, delivering the full PC5-44800 bandwidth the board supports.

Is this a standard DDR5 RDIMM or a different interface, and what does that limit?

These are 288-pin DDR5 RDIMMs; the registered interface lets all eight slots run fully populated at 5600 without down-clocking.
