Yo, NAS boss! You’re staring down the Synology D4NESO-2666-4G – the one and only official 4 GB DDR4-2666 SO-DIMM stick that Synology themselves bless for your DiskStation or RackStation.

This is the exact module you want when you’re tired of memory warnings and ready to unlock the full potential of DSM 7/8.

No more “out of memory” warnings
