Kingston KSM56R46BD8-32HA 32GB Memory Module

The Kingston KSM56R46BD8-32HA represents the vanguard of server memory technology, engineered for next-generation data centers, high-performance computing (HPC) clusters, and mission-critical enterprise servers. This 32GB DDR5 module isn't just an incremental upgrade; it's a foundational shift, built upon the new DDR5 architecture to deliver profound improvements in bandwidth, power efficiency, reliability, and signal integrity. As servers evolve to handle artificial intelligence, big data analytics, virtualization, and massive-scale cloud services, memory subsystems become the critical path to performance.

Core Key Specifications

At its heart, the KSM56R46BD8-32HA is defined by a precise set of technical parameters that dictate its performance profile and compatibility. Understanding these specifications is crucial for system architects and IT procurement specialists.

Memory Capacity and Density

This module offers a substantial 32 Gigabytes (GB) of memory capacity. This density is ideal for populating multi-socket server motherboards to achieve high total system memory configurations (e.g., 512GB, 1TB, or more) without exceeding the physical DIMM slot count. The 32GB capacity strikes a balance between cost-effectiveness per gigabyte and the thermal/power constraints of high-density server environments.

2Rx8 Organization

The "2Rx8" designation indicates a dual-rank module with an x8 data width. A rank is an independently addressable set of DRAM chips. A dual-rank (2R) module effectively allows the memory controller to interleave operations between the two ranks, improving overall efficiency and throughput compared to a single-rank module of the same capacity, though with a slight increase in loading on the memory channel. The x8 configuration refers to the data width per DRAM chip, which is a standard and optimized design for server RDIMMs.

Speed and Performance Metrics

Performance is a cornerstone of this DDR5 module, directly impacting system throughput and application responsiveness.

DDR5-5600MHz and PC5-44800

The module operates at a data rate of 5600 Megatransfers per second (MT/s), commonly referred to as DDR5-5600. This translates to a peak theoretical bandwidth per module. The "PC5-44800" nomenclature is the module's classification under JEDEC standards, where 44800 represents the bandwidth in megabytes per second (MB/s) for the module's 64-bit data path (5600 MT/s * 8 bytes = 44,800 MB/s). This represents a substantial increase over previous-generation DDR4-3200 (PC4-25600) modules, offering over 75% more bandwidth to feed hungry multi-core CPUs.

CAS Latency (CL46)

The Column Access Strobe Latency is rated at CL46. While higher in number compared to DDR4 latencies due to the inherent architectural changes and much higher speeds of DDR5, this latency must be considered within the context of the significantly faster clock cycles. The overall absolute latency in nanoseconds (ns) often remains similar or improved. The CL46 timing is optimized for the stability and performance needs of enterprise systems running at 5600MT/s.

Power Efficiency

A key advancement of DDR5 is its improved power efficiency. The KSM56R46BD8-32HA operates at a standard voltage of 1.1V, a reduction from DDR4's typical 1.2V. This lower voltage directly reduces power consumption and heat generation at the module level, which is critically important when aggregating the savings across hundreds or thousands of modules in a data center. The power management integrated circuit (PMIC) is now located on the DDR5 module itself, rather than on the motherboard. This allows for more granular and stable power delivery, reducing noise and improving signal integrity for reliable operation at high speeds.

Advanced Error Correction and Reliability Features

For enterprise environments, data integrity and system uptime are non-negotiable. The KSM56R46BD8-32HA incorporates multiple layers of protection.

ECC and Registered Design (ECC RDIMM)

This is an Error-Correcting Code (ECC) Registered DIMM (RDIMM). ECC capability detects and corrects single-bit memory errors on-the-fly and can detect multi-bit errors, preventing silent data corruption that could lead to application crashes, calculation errors, or system instability. The "Registered" component refers to the presence of a register (or buffer) on the module for the address and command lines. This register reduces the electrical load on the server's memory controller, enabling support for a higher number of DIMMs per channel and more stable operation in densely populated memory configurations, which is essential for scalable server platforms.

On-Die ECC (ODECC)

As part of the DDR5 standard, this module includes On-Die ECC. This is an additional, independent ECC mechanism that operates within each individual DRAM chip to correct internal errors before they are seen by the system-level ECC. This two-tiered approach (ODECC + traditional side-band ECC) significantly improves the module's reliability and longevity by constantly scrubbing errors at the earliest possible stage.

Compatibility and Integration

The module is designed for seamless integration into qualified server platforms.

288-Pin DIMM Form Factor

The physical interface is a 288-pin Dual In-Line Memory Module (DIMM). The DDR5 pin layout is different from DDR4, featuring a modified key notch position to prevent accidental insertion into an incompatible slot. The design ensures proper physical installation in supported DDR5 server motherboards.

Platform Compatibility

The Kingston KSM56R46BD8-32HA is engineered for compatibility with next-generation server platforms from major OEMs and motherboard manufacturers that support DDR5 ECC RDIMMs. This includes platforms based on Intel Xeon Scalable Processors (e.g., Sapphire Rapids, Emerald Rapids, and beyond) and AMD EPYC Processors (e.g., "Genoa" and subsequent generations). It is imperative to always consult the system or motherboard manufacturer's Qualified Vendor List (QVL) to ensure validated compatibility for specific configurations.

Application and Use Case Scenarios

The specific capabilities of the KSM56R46BD8-32HA make it ideally suited for a range of demanding computing environments.

High-Density Virtualization Servers

In virtualized environments running VMware vSphere, Microsoft Hyper-V, or similar hypervisors, large pools of fast, reliable memory are essential for hosting numerous virtual machines (VMs). The 32GB density and high bandwidth of these modules allow for greater VM density per host, improving consolidation ratios and overall data center efficiency while ensuring smooth performance for each workload.

In-Memory Databases and Real-Time Analytics

Platforms like SAP HANA, Oracle Database In-Memory, and other real-time analytics engines load entire datasets into RAM for instantaneous query processing. The speed of DDR5-5600 directly reduces data access latency, while the high capacity and ECC protection ensure large datasets can be held securely in memory without risk of corruption, accelerating business intelligence and decision-making processes.

Mission-Critical Enterprise Applications

For large-scale ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), and financial transaction processing systems, system stability and data integrity are paramount. The ECC RDIMM design of this Kingston module provides the necessary resilience to maintain continuous operation and protect the integrity of core business data against memory errors.
