PHS-memory 8GB DDR4 ECC UDIMM 2133MHz Memory for Synology RackStation RS3618xs SP266798

Built specifically for the Synology RackStation RS3618xs, this PHS-memory module delivers 8GB of DDR4 ECC UDIMM memory at 2133MHz. Unlike generic unbuffered DIMMs, it includes error-correcting code to detect and fix single-bit memory errors, which is essential for always-on NAS environments where data integrity is non-negotiable.

Highlights

• 8GB capacity, DDR4 technology, 2133MHz speed
• ECC UDIMM with 288-pin DIMM form factor
• 1.2V low-voltage operation for energy-efficient servers
• Validated for Synology RackStation RS3618xs

In daily use

Installing this module in your RS3618xs expands total memory headroom for virtualization, file services, and backup tasks. ECC support reduces the risk of silent data corruption during heavy I/O, and the 2133MHz clock keeps latency low without pushing power consumption beyond the 1.2V DDR4 standard.
