Two green 288-pin DDR4 LRDIMM modules, no heat spreader

OWC

OWC 128GB (2x64GB) DDR4 3200MHz CL22 4Rx4 ECC LRDIMM 1.2V 288-pin Server RAM

SKU CH-00PS-J8G87

Dual-channel 128GB kit of DDR4 3200MHz ECC load-reduced LRDIMMs for servers and workstations

  • Capacity128GB (2 x 64GB)
  • Type288-Pin DDR4 ECC LRDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.2V
  • ECCYes

Capacity 128GB (2 x 64GB)

  • ECC load-reduced design protects data integrity in servers and workstations
  • Dual-channel 2 x 64 GB kit delivers 128 GB total capacity
  • DDR4 3200 MHz CL22 speed with backward compatibility to 2133, 2400, 2666 and 2933 MHz
  • 2 V low-voltage operation reduces power draw
  • 288-pin LRDIMM form factor fits compatible server, workstation and NAS systems

Server Capacity and Role

This 128GB kit delivers two 64GB DDR4 3200MHz ECC LRDIMMs for servers, workstations and NAS systems. The load-reduced design targets platforms that require registered memory with error correction and cannot accept standard unbuffered desktop modules.

Thermals and Power

Modules operate at 1.2V without heat spreaders, relying on system airflow for cooling. The JEDEC-standard voltage keeps power draw predictable in densely populated memory channels typical of multi-socket servers.

Upgrade Context and Limits

The kit replaces or adds to existing DDR4 2133MHz, 2400MHz, 2666MHz or 2933MHz LRDIMM populations and will downclock to match the slowest installed speed. It is not compatible with unbuffered memory or consumer desktop boards that lack LRDIMM support.

Perguntas sobre este artigo

How do I install the 288-pin LRDIMM modules and what step is commonly missed?

Align the notch on each 64 GB module with the key in the server DIMM slot, press firmly until both retention clips click, then verify in BIOS that all 128 GB are detected at 3200 MHz; the step often missed is confirming the memory mode is set for Load Reduced ECC rather than standard UDIMM.

What maintenance or replacement will the 4Rx4 ECC LRDIMM kit need over time?

The modules have no heat spreaders or moving parts, so no routine maintenance is required; replacement is only necessary if a module fails ECC error correction or if a future platform upgrade demands a different DDR generation.

What limit appears first when the dual-channel 3200 MHz kit runs under sustained load?

The CL22 latency at 1.2 V is the primary constraint; sustained throughput will plateau at the JEDEC PC4-25600 rating before thermal or voltage limits become a factor.
