HPE 850883-001 128GB 2666MHz DDR4 LRDIMM server RAM

SKU CH-5MBP-E3PHJ MPN 850883-001

Adds 128 GB of DDR4 server memory at 2666 MHz with ECC registered reliability

  • 128 GB capacity in a single module for high-density server configurations
  • 2666 MHz DDR4 speed delivers fast data throughput for demanding workloads
  • ECC registered design with CL19 latency protects data integrity in critical applications
  • 2 V operation and 8Rx4 organisation reduce power draw while maximising bandwidth

High-capacity DDR4 LRDIMM for Gen10 servers

This 128 GB module uses load-reduced DDR4 technology to deliver large memory density in a single 288-pin slot. ECC registered operation with an 8Rx4 organisation protects data integrity in mission-critical workloads. The kit is qualified for HPE ProLiant Gen10 platforms and runs at 1.2 V.

Sustained throughput at 2666 MHz with CL19 latency

Rated at PC4-21300, the module maintains its rated bandwidth during extended compute jobs rather than only in short bursts. The registered buffer and load-reduced design reduce electrical load on the memory controller, helping stability when all channels are populated. Thermal characteristics remain consistent under continuous utilisation.

Questions about this item

How much power does the 1.2V DDR4 LRDIMM draw when running continuously in a ProLiant Gen10 server?

The module operates at 1.2V; total power depends on how many 128GB sticks are installed and the server workload.

What server hardware is required for this 288-pin LRDIMM to function?

It requires an HPE ProLiant Gen10 server with DDR4 memory slots that support 2666MHz ECC registered 8Rx4 LRDIMMs.
