NEMIX RAM

NEMIX RAM 128GB DDR4 3200 PC4-25600 CL22 1.2V 288-Pin ECC RDIMM 4Rx4 server RAM

SKU CH-PGAN-H6FKP

A 128GB DDR4 3200 ECC registered DIMM with CL22 latency, 1.2V operation and 4Rx4 organisation for server workloads

  • Total capacity128 GB
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Rated voltage1.2 V
  • Buffer typeRegistered

Capacity 128GB

  • 128 GB single-module capacity maximises slot efficiency
  • Registered ECC design protects data integrity in servers
  • DDR4 3200 speed delivers high throughput bandwidth
  • 20 V operation reduces power draw per module
  • 4Rx4 organisation enables dense memory configurations

128 GB DDR4 ECC RDIMM for servers

This 128 GB DDR4 3200 module delivers 1.20 V registered ECC memory in a single 288-pin RDIMM. It targets administrators who need maximum capacity per slot for virtualisation hosts or database servers.

Suits single-slot capacity upgrades.

The 4Rx4 registered design requires a motherboard that supports load-reduced or registered DDR4 ECC. Builders using consumer desktop platforms or unbuffered workstation boards should look at something else.

Press into approved DIMM slots; verify BIOS revision

Installation follows standard RDIMM seating in compatible server chassis. Most issues arise when the system BIOS lacks the microcode for 128 GB 4Rx4 modules, so confirm vendor qualification before deployment.

Questions about this item

Does my server motherboard need a 288-pin DDR4 RDIMM slot that supports ECC and registered memory for this module to work?

Yes, the module is a 288-pin DDR4 RDIMM with ECC and registered buffering, so the motherboard must provide a matching slot and chipset support for registered ECC memory.

Can I add this 4Rx4 128GB stick alongside existing 1Rx4 or 2Rx4 DDR4 3200 modules in the same server?

Mixing ranks is possible if the motherboard and memory controller support mixed-rank populations, but the system will typically run all modules at the lowest common speed and may require specific slot placement per the board manual.

How can I confirm the module is running at DDR4 3200 with CL22 latency after installation?

Check the BIOS memory information screen or use a tool such as CPU-Z or dmidecode to verify the reported speed shows 3200 MT/s and the timings show CL22 at 1.20V.
