QNAP RAM-64GDR4ECK0-RD-3200 64GB DDR4-3200 ECC R-DIMM
Overview
The RAM-64GDR4ECK0-RD-3200 is a 64GB DDR4-3200 ECC Registered DIMM (288-pin) designed as a factory-qualified memory expansion module for QNAP's high-density NAS and storage platforms. ECC (Error-Correcting Code) registration is non-negotiable in always-on NAS environments — it detects and corrects single-bit memory errors in real time, protecting data integrity under sustained multi-drive I/O workloads where a silent memory fault could corrupt a RAID set or ZFS volume. Running at 3200 MHz, it pairs with QNAP NAS units that specify DDR4 RDIMM support, delivering the bandwidth needed to sustain parallel read/write operations across large drive arrays without the memory bus becoming a bottleneck. If you are expanding capacity in a qualified QNAP system, this 64GB module covers high-channel-count configurations where smaller DIMMs would exhaust available slots before reaching target memory headroom.
Compatibility
Verified compatible with the QNAP NAS TS-h1290FX (AMD EPYC 7232P/7252 platform), which ships with 64GB RDIMM DDR4 and supports this module as a qualified expansion or replacement DIMM. The TS-h1290FX requires DDR4 R-DIMM specifically — standard unbuffered UDIMMs are not supported on that platform. Before installing in any other network-attached storage system, confirm the motherboard explicitly lists DDR4-3200 RDIMM 288-pin support; mixing RDIMM and UDIMM slots is not possible and will prevent POST. For QNAP platforms with ZFS-based QuTS hero OS, maximizing installed ECC memory directly expands the ARC (Adaptive Replacement Cache), improving random-read performance on spinning-disk arrays — a tangible benefit at this capacity tier. Consult QNAP's NAS memory compatibility list for your specific model before ordering.
Installation Notes
This is a 288-pin RDIMM — handle by edges only to avoid static discharge; standard ESD precautions apply. Power down the NAS fully before installation (hot-swap is not supported for system memory). Seat the module until both retention clips engage audibly. Populate DIMM slots per your platform's channel-pairing guide to maintain dual- or quad-channel bandwidth; refer to the TS-h1290FX hardware manual for recommended slot population order when mixing capacities.
