OWC 2R9D48R4128G 128GB DDR4 2933 ECC Registered RDIMM memory upgrade

SKU CH-JP1F-F6XP7

128 GB DDR4 2933 ECC registered RDIMM for Lenovo ThinkAgile Xeon SP Gen 2 servers

  • Capacity128GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS Latency21
  • Voltage1.2V
  • ECCYes
  • 128GB single module expands server capacity
  • DDR4 2933 speed matches Xeon SP Gen 2 platforms
  • ECC registered design protects data integrity
  • 2V operation reduces power draw
  • Backward compatible with 2133, 2400, 2666MHz systems

Targeted server upgrade

This 128GB DDR4 2933 ECC Registered RDIMM is built for Lenovo ThinkAgile HX3321, HX3520-G, HX3521-G, HX5520 and HX5521 systems. It serves administrators who need maximum single-module capacity in those Xeon SP Gen 2 platforms without mixing memory types.

Registered ECC construction

The 288-pin module operates at 1.2V with CL21 latency and an 8Rx4 rank structure. Because it is registered ECC, it cannot be used in standard desktops or mixed with unbuffered or load-reduced DIMMs, ensuring signal integrity in multi-DIMM server configurations.

Replaces lower-capacity RDIMMs

Installing this module upgrades from smaller registered DIMMs when the workload demands more memory per slot. The jump is worthwhile when the ThinkAgile node hits capacity limits and the platform’s qualified-vendor list confirms this part number.
