QNAP RAM-32GDR5ECT0-UD-4800 32GB DDR5 ECC UDIMM Memory Module
Overview
The RAM-32GDR5ECT0-UD-4800 is a 32GB DDR5 ECC UDIMM running at 4800MHz, engineered for QNAP NAS appliances that demand both high throughput and error-correcting reliability. ECC (Error-Correcting Code) memory detects and corrects single-bit memory errors in real time — a meaningful safeguard in always-on storage environments where silent data corruption can propagate across a RAID array before anyone notices. At 4800MHz, this module delivers roughly 1.5× the clock speed of DDR4-3200 equivalents, directly reducing latency on metadata-heavy workloads like simultaneous NAS virtualization, snapshot management, and concurrent surveillance stream indexing.
Compatibility
This module is confirmed compatible with QNAP systems that specify QNAP NAS appliances supporting DDR5 UDIMM with optional ECC, including the TS-h1677AXU-RP. That platform provides 4 x UDIMM DDR5 slots with a maximum addressable capacity of 192GB (4 × 48GB). The RAM-32GDR5ECT0-UD-4800 is suited to network-attached storage systems built on AMD Ryzen 7 7000 Series platforms, where the memory controller natively supports DDR5 ECC UDIMM. For dual-channel configurations, QNAP requires pairs of identical DIMMs — mix-and-match modules will drop to single-channel or fail to POST entirely. Verify your specific NAS model's QVL (qualified vendor list) before ordering; DDR5 ECC UDIMM support varies by platform even within the same QNAP product line. Consult the NAS memory and storage planning guide if you are sizing capacity across multiple expansion slots.
Installation Notes
Power down the NAS and discharge static before handling. DDR5 UDIMMs are keyed differently from DDR4 — the notch position prevents accidental slot insertion, but confirm your chassis accepts UDIMM form factor (not SO-DIMM or RDIMM). Seat the module until both retention clips engage. For dual-DIMM configurations, populate matching slots as specified in the chassis silkscreen or service manual — asymmetric population on this platform forces single-channel operation and cuts effective memory bandwidth roughly in half. No tools required beyond standard ESD precautions.
