Technical Overview
This module implements DDR5-5600/PC5-44800 memory standard, providing a peak transfer rate of 5600 million transfers per second. The registered (RDIMM) architecture buffers command and address signals to reduce electrical load on the memory controller, enabling higher module counts and greater capacity per channel in multi-DIMM configurations.
ECC functionality continuously detects and corrects single-bit errors, while registered signal integrity minimizes timing skew and signal degradation across dense server memory arrays. The 1.10V operating voltage represents a power-efficiency improvement over previous DDR generations, reducing thermal output and energy consumption in 24/7 operational scenarios.

User Manual
FAQ
What does 'Registered ECC' mean for this memory module?
Registered ECC combines two server-grade technologies. 'Registered' refers to signal processing that buffers command and address signals, reducing electrical load on the memory controller to support more DIMMs per channel. 'ECC' (Error-Correcting Code) continuously detects and corrects single-bit memory errors during operation. Together, they provide enhanced stability, scalability, and data integrity for critical server applications where uptime and reliability are essential.
Is this DDR5 memory compatible with my existing DDR4 server?
No, DDR5 memory modules are not compatible with DDR4 systems. They use a different physical design with 288 pins compared to DDR4's 288 pins (though the pin layouts differ), different voltage requirements (1.10V vs. typically 1.2V for DDR4), and incompatible signaling technology. The KSM56R46BS8-16HA requires a server motherboard specifically designed for DDR5 memory with support for registered ECC modules. Always verify your system's memory specifications before purchase.
What is the difference between single-rank and dual-rank memory?
Rank refers to how memory chips are organized on the module. Single-rank modules have one set of memory chips that the memory controller accesses at a time, while dual-rank modules have two sets that the controller can address separately. Single-rank modules typically place less electrical load on the memory controller, which can allow for higher operating frequencies or more modules per channel in some configurations. This single-rank design is optimized for performance and compatibility in server platforms supporting this architecture.
Can I mix this Kingston module with other brands of server memory?
While technically possible in some systems, mixing memory modules from different manufacturers, even with identical specifications, is not recommended for server environments. Differences in component sourcing, firmware timings, and manufacturing tolerances can cause stability issues, especially with registered ECC memory where precise signaling is critical. For optimal reliability, install identical modules from the same manufacturer and production batch, and consult your server manufacturer's memory configuration guidelines.
What types of servers typically use registered ECC DDR5 memory?
Registered ECC DDR5 memory is standard in enterprise servers, data-center racks, high-performance workstations, and storage systems. Common applications include virtualization hosts, database servers, computational research clusters, cloud infrastructure, and network-attached storage. The compatibility list for this module includes ASRock server platforms and workstation motherboards, ASUS server models, and other systems designed for registered DDR5 memory where data integrity and continuous operation are priorities.
How does the 1.10V operating voltage benefit server deployments?
The 1.10V operating voltage represents improved power efficiency compared to previous DDR generations. Lower voltage reduces power consumption and heat generation, which is particularly valuable in dense server deployments with many memory modules. Reduced thermal output allows for better cooling efficiency and potentially higher memory density within thermal design limits. This efficiency contributes to lower operational costs and improved energy utilization in 24/7 data-center environments where power and cooling are significant expenses.
