  • Capacity128GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS Latency32
  • Voltage1.10V
  • ECCYes
  • 128 GB capacity handles heavy server workloads
  • DDR5 6400 speed delivers high data throughput
  • ECC registered design corrects errors for reliability
  • 2Rx4 dual-rank organisation increases memory density
  • 10 V operation matches DDR5 standard voltage

Server-grade 128GB DDR5 RDIMM

This registered ECC module delivers 128GB of DDR5 memory at 6400MHz for servers and workstations that require error correction and signal integrity. The 2Rx4 organisation and 1.10V operation suit high-density platform configurations.

288-pin registered form factor without heat spreader

The standard DDR5 RDIMM edge connector fits compatible server mainboards directly, while the registered buffer reduces electrical load on the memory controller. Absence of a heat spreader allows tighter DIMM spacing in dense chassis.

128GB single-module capacity

One module provides 128GB, so total system memory scales with the number of populated slots. Buyers who need more than 128GB per channel or who require unbuffered UDIMM modules should look elsewhere.

Questions about this item

What does the DDR5 6400 PC5-51200 rating mean for actual data throughput?

The module runs at DDR5 6400 with a PC5-51200 designation, delivering registered ECC performance at CAS latency 32 for server workloads.

Will this 288-pin RDIMM fit in a standard server DIMM slot?

Yes, it uses the 288-pin DDR5 RDIMM form factor and 2Rx4 organisation, matching the physical slot and electrical layout of compatible server boards.

How is the module installed and what seating step is often missed?

Align the notch with the slot key, press firmly until both side latches click, then verify the system sees the full 128GB capacity per module in BIOS.
