QNAP RAM-8GDR4I0-UD-3200 8GB DDR4 Unbuffered Memory Module

Overview

The RAM-8GDR4I0-UD-3200 is an 8GB DDR4-3200 unbuffered DIMM sourced and validated by QNAP for use in compatible QNAP NAS enclosures. If you are expanding memory on a QNAP NAS to support more concurrent VMs, heavier containerized workloads, or larger network-attached storage caching layers, this module is the low-risk path — QNAP validates it against their firmware and hardware before listing it as a supported option, which reduces the risk of compatibility issues that can arise from third-party DIMMs at DDR4-3200 speeds.

Compatibility

This module is designed for QNAP NAS systems that accept standard unbuffered DDR4 SO-DIMMs or UDIMMs at 3200MHz. Verify your specific enclosure's qualified memory list before ordering — not all QNAP units accept unbuffered DDR4-3200; some require ECC or SO-DIMM form factor instead. Compatible enclosures typically include select TVS-h and TS-h series units with desktop or tower chassis that use standard UDIMM slots. Confirm slot count, maximum per-slot capacity, and whether your unit supports mixed-capacity configurations before pairing with existing installed memory upgrades.

Installation Notes

Power down the NAS completely and disconnect the power cable before handling memory modules — DDR4 is sensitive to electrostatic discharge. Seat the module firmly until both retention clips engage. After installation, QNAP's system UI will report updated memory capacity on the next boot; no manual configuration is required. If the system fails to POST or reports a memory error, reseat the module and verify the slot is on the QNAP qualified memory list for your enclosure model. Mixing speeds is not recommended — if your enclosure already has DDR4-2666 installed, the system may downclock all slots to the lower speed.
