Its 6400MT/s data rate places it among the fastest commercially available DDR5 RDIMM modules, delivering exceptional throughput for memory-intensive applications.

DDR5 Architecture

DDR5 SDRAM introduces a wide range of architectural improvements over DDR4, significantly enhancing overall system performance. One of the most notable improvements is the doubling of bank groups and banks per memory die, enabling higher levels of parallelism and improved memory access efficiency. The Hynix HMCG88AHBRA285N takes full advantage of this architecture by delivering a sustained data rate of 6400MT/s, translating into a theoretical bandwidth of 51,200MB/s per module. This dramatic increase in bandwidth is critical for modern workloads that rely on rapid data movement between memory and processors. High-performance computing tasks, virtualization environments, and real-time analytics platforms benefit from reduced memory bottlenecks, resulting in faster query execution, improved responsiveness, and better overall system throughput. The DDR5 design also incorporates on-die ECC functionality at the chip level, complementing the module-level ECC to further enhance data integrity. DDR5 memory also introduces a more efficient command and addressing scheme, reducing command bus contention and improving memory scheduling efficiency. This allows servers equipped with DDR5 RDIMM modules like the Hynix HMCG88AHBRA285N to achieve better performance scalability as memory capacity and channel configurations increase. The result is a memory subsystem that is not only faster but also more adaptable to evolving server architectures.

High-Speed 6400MT/s

The 6400MT/s data rate of the Hynix HMCG88AHBRA285N represents a significant leap forward in server memory performance. This transfer rate enables faster data movement between the CPU and memory, reducing latency and increasing throughput for memory-intensive tasks. Compared to earlier DDR5 modules operating at 4800MT/s or 5600MT/s, this module delivers noticeably higher performance, particularly in applications that depend on sustained memory bandwidth. High-speed memory is especially critical for workloads such as large-scale virtualization, in-memory databases, scientific simulations, and AI training models, where rapid access to vast datasets is essential. The increased bandwidth provided by this module ensures that CPUs are not starved for data, allowing them to operate at maximum efficiency and deliver optimal performance across a wide range of applications.

Optimized Latency

Latency is a key factor in memory performance, particularly in workloads that involve frequent memory access or random data retrieval. The Hynix HMCG88AHBRA285N features a CAS latency of CL46, which is carefully optimized to balance high data rates with stable performance. This balance between frequency and latency ensures that the module delivers consistent and predictable performance across a wide range of server workloads. Applications that rely on low-latency memory access, such as transaction processing systems and real-time analytics platforms, benefit from reduced access times and improved response rates, contributing to overall system efficiency and user satisfaction.

Dual Rank x8

The Hynix HMCG88AHBRA285N features a dual rank x8 configuration, which plays a critical role in optimizing memory performance and capacity utilization in server environments. Dual rank memory modules contain two independent sets of memory chips, allowing the memory controller to interleave access between ranks. This interleaving improves memory access efficiency and increases overall throughput by enabling better utilization of available memory channels. The x8 organization refers to the data width of each memory chip, which is optimized for server-class ECC memory implementations. This configuration ensures compatibility with a wide range of server platforms and memory controllers, while also supporting advanced error correction mechanisms. The dual rank design enhances memory scalability, allowing servers to support higher total memory capacities without sacrificing performance or stability.

Optimized for Server Memory

Server memory controllers are designed to work optimally with registered, dual rank memory modules, providing improved signal integrity and higher supported memory capacities.

Its standardized RDIMM form factor and compliance with JEDEC DDR5 specifications ensure seamless integration into existing and future server infrastructures.

ECC

Error Correction Code (ECC) support is a fundamental requirement for server memory, particularly in environments where data integrity and system uptime are paramount. The Hynix HMCG88AHBRA285N incorporates advanced ECC functionality to detect and correct single-bit memory errors and detect multi-bit errors, preventing data corruption and system crashes that could result from uncorrected memory faults. ECC memory is essential for applications such as financial transactions, healthcare data processing, scientific research, and enterprise resource planning systems, where even minor data errors can have significant consequences. By implementing robust ECC mechanisms, this module ensures that data stored in memory remains accurate and reliable, contributing to overall system stability and operational confidence.

Registered DIMM

The Hynix HMCG88AHBRA285N is a Registered DIMM (RDIMM), meaning it incorporates a register between the memory controller and the DRAM chips. This register buffers control signals, reducing electrical load on the memory controller and improving signal integrity, particularly in systems with high memory capacities or multiple memory modules per channel. RDIMM design is essential for server platforms that require high memory densities and stable operation under heavy workloads. By buffering signals, RDIMM modules allow memory controllers to support more memory modules per channel, increasing overall system memory capacity without compromising performance or reliability. This makes RDIMM modules like the Hynix HMCG88AHBRA285N ideal for enterprise servers, workstations, and data center systems.

Enhanced Scalability

As server workloads continue to grow in complexity and scale, the demand for higher memory capacities has increased significantly. RDIMM modules enable servers to support larger memory configurations by reducing signal loading and maintaining stable communication between the memory controller and DRAM chips. The Hynix HMCG88AHBRA285N supports these high-capacity configurations, allowing system builders to maximize memory density and performance. This scalability is particularly important for applications such as virtualization, large-scale databases, and in-memory analytics platforms, which require substantial memory resources to operate efficiently. By enabling higher memory capacities without sacrificing stability, this module supports the evolving needs of modern enterprise computing environments.
