Frequently Asked Questions
What is an LRDIMM and why does it matter?
Load-reduced LRDIMM modules feature a register that buffers address and command signals, reducing electrical load on the server's memory controller. This enables higher memory density per socket, improved stability, and better performance in multi-socket enterprise systems compared to standard RDIMM modules.
Is this memory compatible with my HP server?
This AddOn module is HP P11040-B21 compatible and works with HP ProLiant and Apollo servers that support DDR4-2933MHz load-reduced memory. Verify your server's memory specifications before purchase to ensure compatibility with quad rank x4 LRDIMM configurations.
What does ECC memory do?
ECC (Error-Correcting Code) memory automatically detects and corrects single-bit memory errors in real-time. This is critical for enterprise and data center environments where data integrity and system uptime are paramount, preventing silent data corruption and unexpected system failures.
How much memory capacity do I need?
128GB capacity is ideal for virtualization, large database workloads, in-memory analytics, and high-performance computing applications. For most enterprise servers, 128GB provides excellent performance headroom for demanding multi-tenant and mission-critical environments.
