About the HPE 8GB (1x8GB) Single Rank x8 DDR4-2666 CAS-19-19-19 Unbuffered Smart Memory Kit

The HPE 8GB (1x8GB) Single Rank x8 DDR4-2666 CAS-19-19-19 Unbuffered Smart Memory Kit (879505-B21) is a factory-certified memory module engineered for HPE ProLiant Gen10 servers. Operating at DDR4-2666 MHz with a CAS latency of 19-19-19, this unbuffered DIMM (UDIMM) is designed to deliver reliable, validated performance in configurations requiring cost-effective, single-rank memory expansion. HPE Smart Memory technology enables the host server to recognize and authenticate the module, unlocking full platform capabilities and advanced memory fault reporting through the HPE Advanced Memory Protection features available in supported Gen10 systems.

As a single-rank x8 organization module, this kit provides an 8GB capacity on a single 288-pin DDR4 DIMM, making it well-suited for workloads where memory channel population efficiency and validated interoperability are priorities. The module operates at 1.2V, consistent with DDR4 power efficiency standards, and is tested and qualified against HPE's Reliable Memory Technology (RMT) framework to ensure system stability across sustained enterprise workloads. HPE Smart Memory identification allows ProLiant Gen10 management firmware to distinguish HPE memory from third-party modules, enabling proactive monitoring and predictive failure alerts through HPE iLO.

This memory kit is positioned for enterprise environments deploying HPE ProLiant ML, DL, and Microserver Gen10 platforms where UDIMM form factor is supported. It is appropriate for general-purpose server deployments including virtualization hosts, edge computing nodes, and branch-office infrastructure where unbuffered DDR4 memory is specified. Worldwide availability through Omnixon Global supports procurement for enterprise IT teams across the UAE, GCC, EMEA, and APAC regions.

Ideal for

  • Capacity expansion of HPE ProLiant Gen10 servers running virtualization platforms such as VMware vSphere or Microsoft Hyper-V in mid-market or branch-office deployments
  • Memory upgrades for HPE ProLiant ML30 Gen10 or DL20 Gen10 tower and rack servers in edge computing or distributed IT infrastructure
  • General-purpose enterprise application servers requiring validated, platform-authenticated DDR4 memory to maintain HPE support eligibility
  • Small-to-medium business server environments where UDIMM-based HPE Gen10 systems require incremental memory scaling without transitioning to registered DIMM configurations
  • Replacement or sparing inventory for HPE ProLiant Gen10 UDIMM-compatible platforms within enterprise datacenter lifecycle management programs
  • Development and test lab server nodes where cost-effective, HPE-certified DDR4 memory is required for validated compatibility with production workload profiles
