Transcend 256GB DDR5 5600 RDIMM (1Rx4)

The Transcend 256GB DDR5 5600 RDIMM (1Rx4) is a high-capacity registered memory module engineered for next-generation enterprise servers and workstations built on platforms supporting DDR5 architecture. Operating at a rated speed of 5600 MT/s with a single-rank, x4 organization, this module delivers the combination of high bandwidth and deep memory capacity that modern data-intensive server platforms demand. Registered (buffered) DIMM technology offloads signal management to the on-module register buffer, enabling stable operation at high density and capacity points across multi-slot server configurations.

Built to DDR5 JEDEC standards, this module incorporates on-die ECC (ODECC) as a native DDR5 feature, alongside support for platform-level ECC to protect workload integrity in always-on enterprise environments. The 1Rx4 organization — single rank using x4-width DRAM components — provides the memory controller with precise access granularity that supports high-bandwidth memory subsystem performance, particularly relevant for AI inference, large-scale analytics, and in-memory database workloads where both throughput and data reliability are non-negotiable.

Transcend manufactures this RDIMM with enterprise-grade quality controls and full compatibility targeting server platforms from leading brands utilizing Intel Xeon Scalable (Sapphire Rapids and later) and compatible AMD EPYC generations with DDR5 RDIMM support. With 256GB per module, dense memory configurations can be achieved per server node, reducing the number of modules required to populate high-capacity memory tiers — a practical operational advantage in high-density datacenter rack deployments serving AI, HPC, virtualization, and cloud infrastructure workloads.

Ideal for

• Large-scale AI and machine learning inference and training nodes requiring high per-socket memory capacity to hold large model weights and datasets in-memory
• In-memory databases and real-time analytics platforms (SAP HANA, Redis, VoltDB) that benefit from maximum addressable memory per server node
• High-performance computing (HPC) clusters executing memory-bound simulation, computational fluid dynamics, and scientific modeling workloads
• Dense virtualization hosts running hundreds of concurrent VMs, where maximizing memory per node directly reduces physical server footprint and power draw
• Enterprise cloud infrastructure nodes requiring reliable, ECC-protected memory across multi-tenant workloads with strict uptime requirements
• Datacenter memory consolidation projects aiming to maximize DRAM capacity per 1U or 2U server slot to reduce rack unit consumption
