QNAP RAM-32GDR4K0-RD-3200 32GB DDR4 RDIMM Memory Module
Overview
The RAM-32GDR4K0-RD-3200 is a 32GB DDR4-3200 registered DIMM (RDIMM) sourced directly from QNAP for use in compatible QNAP NAS and server platforms. Registered DIMMs are required in ECC-RDIMM slots — installing unbuffered (UDIMM) memory in an RDIMM-spec system will not POST, making module compatibility non-negotiable before you order. At 32GB per slot, this module lets you maximize memory density on multi-bay systems running memory-intensive workloads such as virtualization (VM Station), containerized applications (Container Station), or ZFS-based storage pools where ARC cache scales directly with installed RAM.
Compatibility
This module is designed for QNAP NAS and rackmount systems that specify DDR4-3200 RDIMM support. Compatible platforms include high-core-count QNAP NAS units in the TVS-h series (such as the TVS-h1288X, TVS-h1688X) and TS-h series (such as the TS-h1290FX, TS-h2490FU) that ship with Xeon or AMD EPYC processors requiring registered ECC memory. Always verify your specific model's memory QVL (Qualified Vendor List) on the QNAP product page before purchasing — slot count, maximum per-slot capacity, and RDIMM vs LRDIMM requirements vary by platform. Do not mix RDIMM and UDIMM modules in the same system; mixed configurations are unsupported and will prevent boot. For systems in a NAS storage deployment running 24/7, using QNAP-validated memory reduces the risk of compatibility-related instability compared to third-party alternatives not on the QVL.
Installation Notes
Power down and ground yourself before handling. Seat the module firmly until both retention clips engage — DDR4 RDIMMs require more insertion force than UDIMMs due to the register chip. Populate slots per the memory installation guide for your platform (typically in matched pairs for dual-channel throughput). After installation, verify the module is recognized at full capacity in the QNAP system health dashboard before returning the system to service.
