Two green DDR4 RDIMM modules with gold contacts and black chips, no heat spreaders

OWC

OWC 3R2D42R4128P 128GB (2x64GB) DDR4 3200 CL22 ECC Registered RDIMM

SKU CH-TQ8Y-3Z1Y0

A 128 GB DDR4 ECC registered RDIMM kit (2 × 64 GB) at 3200 MHz CL22 for select Supermicro H12SSL and H12SSW motherboards

  • Total capacity128 GB (2 × 64 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • CAS latencyCL22
  • Rated voltage1.2 V
  • Buffer typeRegistered

Capacity 128GB (2 x 64GB)

  • ECC registered design protects data integrity in servers
  • 128GB kit (2 x 64GB) expands memory capacity for heavy workloads
  • DDR4 3200 speed with CL22 latency delivers responsive performance
  • 2V operation reduces power draw in dense configurations
  • Validated for Supermicro H12SSL and H12SSW motherboards

Targeted Server Upgrade

This 128GB kit provides two 64GB DDR4 3200 CL22 ECC Registered RDIMMs validated for Supermicro H12SSL and H12SSW motherboards. It is built for workstations and servers that require registered, error-correcting memory at 1.2V. Standard desktop PCs cannot use these modules.

Registered ECC Difference

Registered buffering and ECC protect data integrity in multi-socket or high-capacity configurations where unbuffered memory would fail. The 2Rx4 organisation and CL22 timing match the Supermicro part numbers listed, so the modules slot in without mixing rules violations.

288-Pin DDR4 Form Factor

Each stick uses the standard 288-pin DDR4 interface with no heat spreader, fitting the DIMM slots on the named boards directly. The kit replaces the listed Supermicro part numbers, letting administrators extend existing infrastructure or populate new builds with matched pairs.

Questions about this item

Will the 64GB modules require a heat spreader replacement later?

No heat spreader is fitted on these 64GB RDIMMs, so there is no spreader to replace.

What latency limit appears first when the 3200MHz kit runs continuously?

The CL22 timing is the fixed latency ceiling for every sustained workload.

How much power do the two 1.2V modules draw during all-day server use?

Each 64GB DIMM operates at 1.2V, so the pair draws power at that voltage continuously.
