PHS-memory 32GB DDR5 ECC UDIMM 5600MHz PC5-44800E RAM per QNAP TVS-AIh1688ATX-U7-32G SP598431

Engineered specifically for the QNAP TVS-AIh1688ATX-U7-32G, this 32GB DDR5 ECC UDIMM module delivers the error-correcting reliability and bandwidth that high-throughput NAS, server, and workstation workloads demand. Unlike standard desktop memory, it combines unbuffered design with ECC to catch and correct single-bit errors, protecting data integrity during continuous operation.

Highlights

• 32GB capacity in a single module, ideal for memory-intensive virtualization, AI inference, and large file transfers
• DDR5 technology with 5600 MHz speed (PC5-44800E) for up to 44.8 GB/s data transfer rate
• ECC (Error-Correcting Code) support to detect and correct memory errors, reducing downtime and data corruption risks
• Unbuffered UDIMM form factor with 288-pin DIMM layout, compatible with systems requiring ECC UDIMM
• Dual Rank (2Rx8) configuration for improved performance in certain memory interleaving scenarios
• Low 1.1V operating voltage for energy efficiency, with CAS latency of CL46

In daily use

Installing this module in the QNAP TVS-AIh1688ATX-U7-32G expands system memory to handle more concurrent tasks, larger databases, and smoother 4K/8K media workflows. The ECC function continuously scans for bit flips, which is critical for long-running NAS operations where silent data corruption could otherwise go unnoticed. With dual rank architecture, memory access is optimized for balanced performance across multiple channels.
