PHS-memory 32GB DDR5 ECC SO-DIMM 4800MHz PC5-38400E RAM pre Asustor Lockerstor 4 Gen3 (AS6804T) SP566019

Upgrading a NAS often means choosing between stability and speed—this PHS-memory module delivers both. Built specifically for the Asustor Lockerstor 4 Gen3 (AS6804T), it pairs 32GB of DDR5 ECC memory with a 4800MHz clock, ensuring that large file transfers, virtualization tasks, and multi-user access never choke on memory errors or bandwidth limits. Unlike generic SO-DIMMs, the ECC engine silently corrects single-bit faults before they can corrupt your data, making it a natural fit for always-on storage servers.

Highlights

• 32GB capacity on a single module, leaving three slots free for future expansion up to 128GB.
• DDR5 architecture with 4800MHz speed and PC5-38400E JEDEC standard for reliable, non-overclocked operation.
• ECC unbuffered design detects and corrects memory errors, critical for ZFS, Btrfs, and RAID parity calculations.
• SO-DIMM 262-pin form factor, engineered for compact NAS enclosures with low 1.1V power draw.
• Verified compatibility with Asustor Lockerstor 4 Gen3 (AS6804T), including mixed-capacity configurations.

In daily use

After installation, the NAS recognizes the full 32GB immediately, and the ECC feature works transparently—no driver or BIOS tweaks needed. During sustained writes to a RAID 5 array, the module stays cool thanks to its efficient voltage and onboard thermal management. For home labs running Docker containers or small business file sharing, this memory keeps latency low even when several users stream 4K media or run backups simultaneously. The unbuffered design avoids the extra latency of registered modules, so applications feel snappy while still gaining the safety net of error correction.
