SKU CH-3P52-J2YM6

A 64 GB dual-channel DDR5 5600 kit with ECC registered DIMMs, CL46 latency and 1.1 V operation for servers and workstations

  • Capacity64GB (2 x 32GB)
  • SpeedDDR5 5600 (PC5 44800)
  • CAS LatencyCL46
  • Voltage1.10V
  • ECCYes
  • Buffered/RegisteredRegistered

Capacity 64GB (2 x 32GB)

  • 64 GB capacity handles large server workloads using two 32 GB modules
  • DDR5 5600 speed with CL46 latency accelerates data-intensive applications
  • ECC registered design detects and corrects memory errors for reliability
  • Single-rank 1Rx4 layout optimises signal integrity on multi-channel platforms
  • Standard 1.10 V DDR5 voltage reduces power draw in dense configurations

64 GB DDR5 Registered ECC Kit

This 64 GB kit contains two 32 GB DDR5 5600 modules built for servers and workstations that require registered ECC memory. Each module uses a single-rank x4 organisation with on-die ECC and runs at the standard 1.1 V. The dual-channel kit targets administrators who need reliable capacity expansion for virtualisation, database or compute workloads.

288-Pin RDIMM Form Factor

The modules follow the 288-pin DDR5 RDIMM standard, so they seat only in platforms designed for registered DDR5 memory. Registered buffering reduces electrical load on the memory controller, while on-die EC8 ECC corrects single-bit errors inside the DRAM. Compatibility is limited to qualified server and workstation boards; desktop or laptop systems will not accept these modules.

Upgrade from Lower-Capacity DDR5 Kits

Replacing smaller registered DDR5 kits with this 64 GB set increases the addressable memory for multi-tenant or data-intensive applications. The jump is worthwhile when the platform supports the full 5600 MT/s data rate and the workload benefits from additional rank density. Systems limited to lower speeds or unbuffered memory cannot use this kit.

Questions about this item

What bandwidth does the PC5-44800 DDR5 5600 interface provide for this kit?

The PC5-44800 rating means the DDR5 5600 interface delivers up to 44800 MB/s of peak bandwidth per module.

What physical slot and pin count does this 288-pin RDIMM require?

Each 32 GB module uses a standard 288-pin DDR5 RDIMM form factor and fits only server or workstation boards with registered DDR5 DIMM slots.

How do I install this dual-channel kit correctly in a server?

Populate both modules in the same memory channel pair — usually slots of the same colour — following the motherboard manual's population order for 1Rx4 registered DIMMs.
