PHS-memory 32GB DDR4 ECC SO-DIMM 2666MHz geheugen voor QNAP TS-435XeU-4G SP556143

Running a QNAP TS-435XeU-4G NAS with only 4GB of RAM quickly leads to sluggish performance when handling multiple users, virtual machines, or heavy data workloads. This PHS-memory 32GB DDR4 ECC SO-DIMM module eliminates that bottleneck, giving your NAS the headroom it needs for smooth operation and reliable data integrity.

Who is it for

This memory upgrade is ideal for IT administrators, small businesses, and advanced home users who rely on a QNAP TS-435XeU-4G NAS for file sharing, backups, virtualization, or surveillance. It's also a perfect fit for anyone who wants to maximize their NAS's lifespan and performance without replacing the entire unit.

Main features

• 32GB capacity – a massive upgrade from the stock 4GB, allowing more concurrent tasks and larger caches.
• DDR4 technology with 2666MHz speed – delivers faster data transfer rates and lower power consumption than DDR3.
• ECC (Error-Correcting Code) support – detects and corrects single-bit memory errors, preventing data corruption and system crashes in always-on NAS environments.
• SO-DIMM form factor – specifically designed for compact NAS enclosures like the TS-435XeU-4G.
• Unbuffered ECC UDIMM – ensures compatibility with the NAS's memory controller while providing error correction.
• 260-pin configuration and 1.2V operating voltage – meets JEDEC standards for DDR4 SO-DIMM modules.
• Plug-and-play installation – simply insert into the available memory slot and boot up; no BIOS tweaks required.

Tips

Before purchasing, verify that your QNAP TS-435XeU-4G has an available memory slot and that its firmware is up to date. For optimal performance, consider installing two identical modules to enable dual-channel mode if supported. Always handle memory modules by the edges to avoid static damage, and power down the NAS completely before installation.
