FAQ
What type of memory module is the AddOn P05590-H21-AM?
The AddOn P05590-H21-AM is a 32GB DDR4 Registered ECC RDIMM (Registered Dual In-Line Memory Module) designed for server use. It features 288 pins, operates at 2666MHz with CL17 latency, and includes Error Correcting Code functionality for automatic error detection and correction in server environments.
What does Registered ECC memory mean for server applications?
Registered ECC memory combines two server-grade features: Registered signal processing reduces electrical load on the memory controller to support higher memory capacities, while ECC (Error Correcting Code) automatically detects and corrects single-bit memory errors. This combination enhances system stability and prevents data corruption in mission-critical server deployments.
What is the operating speed and latency of this memory module?
This DDR4 memory module operates at 2666MHz with CAS Latency 17 (CL17). The 2666MHz frequency provides the memory bandwidth needed for server workloads, while the CL17 timing represents the number of clock cycles between a memory request and data availability, balancing performance with reliability in enterprise environments.
Is this memory module compatible with my HP server system?
This module is designed as a compatible factory original replacement for HP P05590-H21 memory. It maintains the same specifications including 32GB capacity, DDR4-2666MHz speed, Registered ECC functionality, and 288-pin RDIMM form factor. Always verify compatibility with your specific server model and existing memory configuration before installation.
What is the form factor and pin configuration of this memory?
This module uses the 288-pin RDIMM (Registered Dual In-Line Memory Module) form factor standard for server memory. The 288-pin configuration ensures proper physical and electrical compatibility with server motherboards designed for Registered memory modules, providing the contacts needed for both data transfer and Registered signal processing functionality.
