About the HPE 16GB 1Rx8 PC4-2666V-E UDIMM Standard Memory
At 16 GB per DIMM, this HPE memory module establishes the per-slot capacity ceiling for HPE ProLiant Gen10 servers, enabling infrastructure teams to maximize installed memory within their chassis constraints. The HPE 16GB 1Rx8 PC4-2666V-E UDIMM (part number 838079-B21) is a DDR4 SDRAM module engineered for mission-critical enterprise deployments where data integrity and system stability are non-negotiable. With ECC error correction, 2666 MT/s performance, and full RoHS compliance, this standard unbuffered DIMM delivers the reliability that storage architects and IT procurement teams demand when consolidating workloads across virtualized infrastructure.
Built to HPE specifications, this 288-pin module features single-rank (1Rx8) architecture with x8 data width and operates at 1.2V, making it thermally efficient and power-conscious for data center environments. The 72-bit data transfer width (64-bit data plus 8-bit ECC) protects against single-bit errors that could compromise database transactions, application uptime, or compliance audits. CAS latency of 19 and operating temperature range of 0°C to 85°C ensure stable performance in both standard and edge-case thermal conditions. Contact Omnixon Global for availability and specifications on this HPE standard memory component.
Enterprise Deployment Scenarios
- Database servers running mixed OLTP and analytical workloads on HPE ProLiant Gen10 platforms requiring maximum installed RAM and ECC protection
- Virtualization hosts consolidating 50+ virtual machines, where memory fault tolerance prevents cascading guest VM failures
- High-availability cluster nodes serving financial, healthcare, or telecommunications sectors where undetected memory corruption is unacceptable
- Multi-tenant cloud environments where isolated tenants must have guaranteed memory performance and error isolation
- Legacy application migrations onto Gen10 infrastructure, pairing familiar DDR4 2666 MT/s speeds with modern ECC reliability standards
