NEMIX RAM 128GB DDR5 5600 4Rx4 CL46 1.1V ECC RDIMM memory upgrade

SKU CH-6N3Q-A5J2Q

A 128GB DDR5 5600 ECC RDIMM module with CL46 latency, 1.1V operation and 4Rx4 registered architecture for compatible Hynix servers

  • Total capacity128 GB
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 128 GB capacity expands server memory headroom for large workloads
  • DDR5 5600 speed delivers high bandwidth for data-intensive tasks
  • ECC registered design detects and corrects errors to protect data integrity
  • 4Rx4 organisation maximises density in a single 288-pin module
  • 1 V operation reduces power draw compared to higher-voltage DDR5 modules

Server RDIMM for Hynix platforms

This 128 GB DDR5 registered DIMM targets IT teams upgrading Hynix-based servers and workstations. It delivers ECC protection and registered signalling for stable operation under sustained enterprise workloads.

4Rx4 organisation at CL46

The module uses a 4Rx4 rank layout with CL46 latency at DDR5-5600. That combination determines whether the memory controller can populate the slot without exceeding electrical load limits.

Single-module 128 GB capacity

One stick adds 128 GB of ECC RDIMM space, letting dense configurations scale within the platform's slot count. Population rules and maximum supported ranks on the target board will define the practical ceiling.

Questions about this item

What does the 5600 MT/s speed mean once the module is installed in a server?

The module runs at 5600 MT/s, delivering DDR5 bandwidth at 1.1 V; actual throughput depends on the platform's memory controller and channel population.

What does the PC5-44800 designation and registered interface mean for system limits?

PC5-44800 denotes the peak data rate; the registered interface adds a clock cycle of latency but allows higher per-channel capacity than unbuffered DDR5.

Will the 288-pin 4Rx4 RDIMM fit my Hynix-compatible server motherboard?

It uses the standard 288-pin DDR5 RDIMM form factor; verify your board supports 4Rx4 registered modules and 128 GB per slot before installing.
