Transcend 64GB DDR4 2666 RDIMM ECC Registered (2Rx4)

The Transcend 64GB DDR4 2666 RDIMM ECC Registered (2Rx4), part number TS512MLH72V2H, is a high-density registered server memory module engineered for enterprise platforms requiring large memory footprints and sustained reliability. Built on a dual-rank, x4 organization with a 288-pin RDIMM form factor, it operates at DDR4-2666 (PC4-21300) speeds and incorporates a registered clock driver that buffers the command and address signals between the host memory controller and the DRAM components. This architecture allows the module to support greater DRAM density per channel while maintaining signal integrity across heavily loaded memory buses — a critical characteristic in multi-DIMM per channel server configurations.

Error-correcting code (ECC) functionality provides continuous single-bit error correction and multi-bit error detection during operation, significantly reducing the risk of silent data corruption in mission-critical environments. The x4 DRAM configuration further enhances ECC effectiveness by enabling SDDC (Single Device Data Correction), which allows the memory subsystem to fully correct any failure confined to a single DRAM device. Operating at 1.2V, the module delivers a balance of performance and power efficiency suitable for always-on datacenter infrastructure. The module adheres to JEDEC standards for DDR4 registered DIMMs, ensuring broad compatibility with server platforms from major brands that support DDR4-2666 RDIMM configurations.

Designed to meet the demands of enterprise IT, datacenter, AI inference, and high-performance computing deployments, the TS512MLH72V2H is manufactured under Transcend's industrial-grade quality control processes. At 64GB capacity, it enables configurations with very large aggregate memory pools per server node when deployed across available DIMM slots, supporting memory-intensive workloads such as in-memory databases, virtualization hosts, and large language model inference. Omnixon Global supplies this module to enterprise and institutional buyers across the UAE, GCC, EMEA, and APAC regions.

Ideal for

• High-density virtualization hosts requiring large per-VM memory allocations across multi-socket server platforms
• In-memory database deployments (e.g., SAP HANA, Redis, VoltDB) where aggregate DRAM capacity directly determines dataset fit and query latency
• AI inference servers and HPC nodes running large language models or data analytics frameworks that benefit from maximized system memory capacity
• Enterprise storage controllers and software-defined storage nodes where memory capacity accelerates caching and metadata operations
• Mission-critical ERP and financial transaction processing systems demanding ECC-protected, continuously available memory subsystems
• Cloud and colocation infrastructure buildouts requiring high-capacity, standards-compliant DDR4 RDIMMs for multi-tenant workload isolation
