QNAP RAM-32GDR4K1-SO-3200 32GB DDR4 SODIMM Memory Module
Overview
The RAM-32GDR4K1-SO-3200 is a 32GB DDR4-3200 SODIMM memory module designed for QNAP NAS systems. Running at 3200 MHz over a 260-pin interface at 1.2V, it targets deployments where a single SODIMM slot needs to be pushed to its per-stick ceiling — whether you're running memory-hungry virtual machines, ZFS ARC caching, or high-concurrency storage workloads that stall under a lighter memory configuration. Installing two of these modules brings compatible dual-slot systems to their 64 GB maximum, the threshold where QTS and QuTS hero start to show meaningful throughput gains on parallel workloads.
Compatibility
Verified compatible with QNAP NAS systems that provide 260-pin SODIMM DDR4 slots and support the DDR4-3200 speed grade, including the QNAP NAS lineup featuring the TS-873AeU (max 64 GB, 2 × 32 GB) and the TS-855eU-RP (max 64 GB, 2 × 32 GB). Both models expose ECC-capable SODIMM slots — the RAM-32GDR4K1-SO-3200 is a non-ECC DDR4 module at this specification; confirm your chassis ECC requirement before ordering. For broader NAS storage upgrade decisions, verify slot count and maximum memory ceiling in your specific model's hardware spec sheet, as QNAP populates memory slots differently across the rackmount and tower product lines. A predecessor SKU, RAM-32GDR4K0-SO-3200 (now EOL), carried the same 32 GB / DDR4 / 260-pin / 3200 MHz / 1.2V specification — this module is the current production replacement for that configuration.
Installation Notes
SODIMM installation requires powering down the NAS completely and grounding yourself before handling the module — DDR4 SODIMMs are static-sensitive. Seat the module at approximately 30 degrees, press down until both retention clips engage audibly. For dual-DIMM configurations on systems like the TS-873AeU and TS-855eU-RP, QNAP requires both slots to be populated with matched modules to reach the 64 GB ceiling; mismatched capacities will run but may reduce effective storage system memory bandwidth. Consult your NAS model's hardware guide for slot assignment order when populating a single module.
