PHS-memory 32GB DDR5 ECC UDIMM 5600MHz PC5-44800E RAM per QNAP TVS-AIh1688ATX-U7D-12H05 (SP598433)

This 32GB DDR5 ECC UDIMM module operates at 5600MHz and is specifically validated for the QNAP TVS-AIh1688ATX-U7D-12H05 NAS. Unlike standard desktop memory, it combines error-correcting code (ECC) with an unbuffered design to protect data integrity in always-on storage environments, while the high clock speed ensures smooth handling of large file transfers and concurrent workloads.

Highlights

• 32GB capacity for demanding NAS applications
• DDR5 technology with 5600MHz data rate
• ECC (Error-Correcting Code) for data reliability
• Unbuffered DIMM (UDIMM) form factor
• PC5-44800E standard, 288-pin, 1.1V
• Compatible with QNAP TVS-AIh1688ATX-U7D-12H05

In daily use

Installed in a QNAP TVS-AIh1688ATX-U7D-12H05, this module provides the memory headroom needed for virtualization, high-resolution media indexing, and multi-user access. ECC support reduces the risk of silent data corruption, while the 5600MHz speed keeps latency low even under sustained I/O. The unbuffered design is a direct match for the NAS's memory controller, ensuring stable operation without the need for registered memory.
