QNAP RAM-32GDR4K0-SO-3200 32GB DDR4 SODIMM Expansion Module
Overview
The RAM-32GDR4K0-SO-3200 is a 32GB DDR4 SODIMM running at 3200 MHz, designed to expand memory in compatible QNAP NAS systems. Installing this module in a two-slot NAS brings total capacity to 64GB — the practical ceiling for dual-DIMM QNAP platforms — which directly reduces swap activity during concurrent VM workloads, heavy transcoding, or multi-app container deployments. If your NAS ships with 8GB stock and you're running resource-intensive applications, a single RAM-32GDR4K0-SO-3200 eliminates the most common performance bottleneck before you ever look at drive configuration.
Compatibility
Verified compatible with QNAP NAS platforms that support SODIMM DDR4 memory expansion, including the TS-855eU-RP series, which accepts up to 2 x 32GB SODIMM DDR4 (64GB maximum). Consult the memory slot specification on your target unit before ordering — QNAP platforms vary between ECC and non-ECC support, and some models accept ECC SODIMMs in the same physical slot. The RAM-32GDR4K0-SO-3200 is the K0 version; confirm your platform's qualified memory list to ensure module compatibility before installation. Mixing module speeds or capacities in a dual-slot configuration can reduce stability; pairing two identical RAM-32GDR4K0-SO-3200 modules is the recommended path to reach the 64GB ceiling.
Installation Notes
SODIMM installation requires powering down the unit completely — hot-swap memory is not supported on QNAP NAS platforms. Ground yourself before handling; static discharge can damage the module or the motherboard slot. Seat the module at a 45-degree angle, press firmly until the retention clips engage on both sides, then confirm detection in the QNAP System Information panel after boot. No tools beyond a Phillips screwdriver (for chassis access) are typically required on rack-form-factor units like the TS-855eU-RP.
