128GB DDR4 3200 ECC RDIMM for ASRock Workstations

This 128GB registered DDR4 module targets ASRock SPC621D8 and SP2C621D16 series workstations and servers. It delivers error-correcting registered memory for applications that require data integrity and high capacity in a single DIMM slot. The 8Rx4 organisation suits platforms qualified for quad-rank registered DIMMs.

Upgrade from lower-capacity

The module replaces smaller registered ECC DIMMs or slower DDR4 speeds such as 2133, 2400, 2666 or 2933 MT/s. The jump is worth it when the platform supports 3200 MT/s PC4-25600 operation and the workload needs the full 128GB density per slot without mixing unbuffered or load-reduced memory types.

Sustained-load behaviour in registered ECC

Registered buffering and on-die ECC maintain signal integrity during continuous multi-threaded workloads typical of server and NAS deployments. The 1.2V operating voltage and JEDEC-standard timings keep power draw predictable while the module runs at rated CL22 latency under prolonged utilisation.

Highlights

  • 128 GB capacity in a single module
  • ECC registered design protects data integrity
  • DDR4 3200 speed with CL22 latency
  • 2 V operation reduces power draw
  • Compatible with ASRock SP series workstations

Questions about this item

Will this 288-pin DDR4 RDIMM fit the memory slots on my ASRock SPC621D8 workstation board?

Yes, the 288-pin DDR4 ECC registered DIMM is designed for the ASRock SPC621D8, SPC621D8-2L2T, SPC621D8-2T, SP2C621D16HM3 and SP2C621D16N-2L2T motherboards.

What is the correct way to install this 128GB 8Rx4 registered module, and what mistake should I avoid?

Align the notch on the module with the key in the DDR4 slot, press firmly until both retention clips click, and do not mix this registered ECC DIMM with unbuffered or load-reduced memory.

Does this 1.2V DDR4 3200 module need any firmware updates or battery changes over its service life?

No firmware updates or battery replacements are required; the module is JEDEC and RoHS compliant and backed by a limited lifetime warranty with free technical support.
