Memory Clock and Cycle Time

The module runs at a 2800MHz memory clock with a cycle time of 0.3571 ns, delivering precise timing and efficient data handling across demanding applications.

Registered DIMM (RDIMM) 

Registered DIMMs use a register (or buffer) between the memory controller and the DRAM chips. This design reduces electrical load on the memory controller, enabling servers to support larger memory capacities and more DIMMs per channel. The Kingston KTD-PE556D8-32G category is optimized for stability in dense memory configurations commonly found in enterprise servers.RDIMM architecture ensures reliable signal integrity, especially at higher DDR5 frequencies such as 5600MHz, making this category suitable for scalable server deployments and memory-intensive applications.

Dual Rank Memory Organization

Dual rank memory design enhances performance by allowing the memory controller to access multiple ranks in an interleaved manner. The Kingston KTD-PE556D8-32G category uses a dual rank configuration to improve throughput and responsiveness, particularly in multi-threaded workloads.Dual rank DDR5 RDIMM modules often provide better real-world performance compared to single rank modules, especially in server environments where sustained memory access patterns are common.

Voltage 1.1V Power Efficiency

DDR5 memory operates at a lower standard voltage of 1.1V, which contributes to improved power efficiency across the system. The Kingston KTD-PE556D8-32G category leverages this lower voltage to reduce overall energy consumption without compromising performance or reliability.Lower power draw is particularly beneficial in data centers, where energy efficiency directly impacts operational costs and thermal management strategies.

288-Pin Form Factor

The 288-pin RDIMM form factor is the industry standard for DDR5 server memory. The Kingston KTD-PE556D8-32G category is designed for compatibility with leading server platforms from major OEMs, ensuring seamless integration into enterprise systems.This standardized design simplifies deployment, upgrades, and maintenance, making it easier for IT teams to manage large server fleets.
