Raise server memory headroom without changing the platform profile with this 128GB DDR4-2933 LRDIMM from AddOn Networks. Designed as an HP P19047-X21 compatible module, it delivers ECC protection, registered signaling, and load-reduced architecture for enterprise systems that need stable operation at high capacity. The 4Rx4 layout is suited to server boards that are engineered for dense memory population. Running at 2,933 MT/s and 1.2 V, this module balances throughput and power efficiency for workloads that spend more time waiting on memory than on raw compute. For infrastructure teams, the advantage is practical: more room for virtual machines, larger database caches, and fewer memory-related constraints during consolidation projects. As a compatible replacement for HP systems, it offers a straightforward path to expanding capacity while staying aligned with platform requirements and procurement standards.
