OWC 128GB DDR4 3200 CL22 4Rx4 ECC LRDIMM memory upgrade HP Apollo 4200 Gen10 Plus

Single-module server upgrade

This 128GB DDR4 3200 CL22 4Rx4 ECC LRDIMM module is built for the HP Apollo 4200 Gen10 Plus. It targets administrators who need maximum capacity per slot in a supported server or workstation platform. The load-reduced design reduces electrical load on the memory bus for stable operation at high density. It will not work in standard desktop systems or alongside unbuffered or registered ECC DIMMs.

Thermals and power profile

The module runs at 1.2V without a heat spreader, relying on chassis airflow for cooling. Load-reduced architecture lowers per-pin current draw compared to standard registered DIMMs at this capacity. JEDEC-compliant operation at PC4-25600 keeps power consumption predictable under sustained server workloads. Backward compatibility with 2133, 2400, 2666 and 2933MHz speeds allows flexible deployment across mixed-speed configurations.

Build integration

The 288-pin DDR4 form factor fits the Apollo 4200 Gen10 Plus memory slots directly. Single-module design leaves remaining slots free for future expansion or matched-population requirements. Replaces HP part numbers P06037-B21, P06037-H21, P06037-K21, P43171-B21, P07652-B21, P07652-H21 and P25206-B21. Buyers needing unbuffered or standard registered ECC memory should choose a different module type.
