Product Features
Product Overview
The Axiom 815102-B21-AX is a 128GB DDR4-2666 ECC LRDIMM engineered for HP server platforms requiring high-capacity, error-correcting memory. This module delivers 128 GB of DDR4 SDRAM operating at 2666 MHz with a CAS latency of CL19 and a low 1.20V power profile. Built as a 288-pin LRDIMM, it is designed for compatibility with HP servers that use the 815102-B21 part number, providing a reliable memory upgrade or replacement solution for data-intensive enterprise environments.
With ECC (Error-Correcting Code) support, this memory module detects and corrects common types of internal data corruption, enhancing system stability and data integrity in mission-critical applications. The LRDIMM (Load-Reduced Dual In-Line Memory Module) form factor allows for higher memory capacities per channel compared to standard RDIMMs, making it ideal for servers that need to maximize total memory without increasing the physical slot count. This module is backed by a lifetime limited warranty and is manufactured with environmentally friendly processes.
Technical Overview
This Axiom memory module adheres to the DDR4-2666 (PC4-21300) standard, providing an effective data rate of 2666 million transfers per second. The 128 GB capacity is achieved through advanced memory chip packaging and LRDIMM architecture, which reduces electrical load on the memory controller to support higher densities. Operating at 1.20V, it aligns with DDR4's lower voltage requirements for improved energy efficiency and reduced heat generation compared to previous DDR3 modules.
The CL19 latency indicates a column address strobe delay of 19 clock cycles, balancing speed with stability for server workloads. The 288-pin interface is specific to LRDIMMs used in server platforms, ensuring proper physical and electrical compatibility with supported HP server motherboards. ECC functionality is implemented through additional memory chips that store parity data, enabling single-bit error correction and multi-bit error detection without requiring operating system or application changes.
Key Product Advantages
This Axiom LRDIMM offers several advantages for server memory upgrades, starting with its high 128 GB capacity that enables larger in-memory datasets and reduces the need for frequent disk access in virtualization, database, and analytics workloads.

FAQ
What is the capacity of this Axiom memory module?
This Axiom memory module has a capacity of 128 GB (gigabytes). This high capacity makes it suitable for server applications that require substantial memory for virtualization, databases, or in-memory processing, allowing systems to handle larger datasets without frequent disk access.
What does DDR4-2666 mean for this memory?
DDR4-2666 indicates this is a DDR4 SDRAM module operating at 2666 MHz (megahertz), which is the data transfer rate. The 'PC4-21300' designation refers to the peak transfer rate of 21,300 MB/s. This speed provides fast memory access for server applications while maintaining compatibility with servers designed for DDR4-2666 memory.
How does ECC benefit this memory module?
ECC (Error-Correcting Code) enables this memory module to detect and correct single-bit errors automatically, preventing data corruption and system crashes. For server environments where data integrity is critical, ECC memory reduces the risk of silent data corruption and improves overall system reliability during continuous operation.
What is an LRDIMM and why is it used here?
