  • 24 GB capacity gives servers more room for complex workloads
  • 5600 MHz DDR5 speed moves data across two independent sub-channels per cycle
  • Registered signal processing reduces electrical load on the memory bus for stable operation
  • On-die ECC with x80 layout corrects bit errors inside the DRAM array
  • CL46 latency with 46-45-45 timing delivers quick data access at 1.10 V

24 GB DDR5 RDIMM for servers

This 24 GB DDR5 registered DIMM targets servers and workstations that require ECC protection and registered signalling. The module runs at 5600 MHz with CL46 latency and operates at 1.10 V. It suits administrators building or expanding memory arrays where data integrity is mandatory.

Sustained-load behaviour with on-die ECC

On-die ECC and x80 ECC across two independent I/O sub-channels correct errors continuously during heavy workloads. Hard and soft post-package repair adds resilience when the system runs at 5600 MHz for extended periods. The 1Rx8 organisation keeps electrical loading low on the memory bus.

Registered signal processing decides fit

Registered buffering reduces the electrical load on the server memory bus, allowing larger configurations than unbuffered modules permit. Buyers who need unbuffered UDIMMs or non-ECC memory for consumer platforms cannot use this part.

Questions about this item

How much power does the 1.10V DDR5 5600 module draw under continuous load?

It runs at 1.10V typical VDD and VDDQ with a 1.8V VPP rail; registered buffering and on-die ECC add minimal overhead, so sustained draw stays low for a 24GB 1Rx8 DIMM.

Does my motherboard need a 288-pin DDR5 RDIMM slot with registered and ECC support to use this module?

Yes, it requires a 288-pin DDR5 RDIMM slot that supports registered signal processing and ECC; the 1Rx8 organisation and CL46 timing are negotiated at boot.

Will the 31.25mm height and 1Rx8 layout fit alongside existing DDR5 RDIMMs in a dense server chassis?

The 1.23in (31.25mm) PCB height matches standard DDR5 RDIMM form factor, and the single-rank x8 design presents one load per channel for broad compatibility.
