Speed 5600MHz

  • 768 GB total capacity from six 128 GB modules
  • DDR5-5600 speed with CL46 latency for rated performance
  • Registered ECC design offloads the controller and corrects single-bit errors
  • 1 V operation matches the server memory controller specification
  • 288-pin RDIMM form factor verified for Supermicro H13SRH motherboard

Exact-match server kit

This 768GB kit contains six 128GB DDR5 RDIMMs rated at 5600MHz PC5-44800 with CL46 latency and 1.1V operation. The modules use 2Rx4 registered ECC architecture built with major OEM chips for the Supermicro H13SRH motherboard.

Installation and pitfalls

The 288-pin registered form factor fits only RDIMM slots; UDIMM or SODIMM sockets will not accept them. Full population requires following the board manual for approved DIMM order and capacity limits per channel.

Suited for and not suited for

Suits administrators upgrading a Supermicro H13SRH to maximum registered ECC capacity with verified timings. Does not suit builds needing unbuffered memory, non-ECC modules, or a different DDR generation.

Questions about this item

How do I confirm the kit is running at DDR5 5600 CL46 after installation?

Enter the BIOS or use a tool such as dmidecode to verify each 128 GB module shows 5600 MT/s, 1.10 V and CAS latency 46; the registered ECC design also logs corrected errors so you can watch the system health log for clean operation.

What exactly ships in the box and is anything else required?

The box contains the six 128 GB 288-pin DDR5 RDIMMs pre-tested as a matched 768 GB kit; no extra cables, brackets or software are needed — just a compatible Supermicro H13SRH motherboard with available DIMM slots.

Why choose this 768 GB (6 × 128 GB) 2Rx4 kit over other capacities?

This 6-module 2Rx4 configuration matches the H13SRH’s optimal population rules for maximum registered ECC capacity at the rated 5600 speed, whereas smaller kits leave slots empty and larger capacities are not supported by this board.
