8 GB DDR3L SODIMM for Synology DS625slim

This 8 GB DDR3L module is built as a direct memory upgrade for the Synology DiskStation DS625slim. It delivers 1866 MHz speed with CL13 latency at 1.35 V in a 204-pin SODIMM form factor. The single stick adds capacity without requiring paired modules.

Check your NAS slot count and current population

The DS625slim uses SODIMM slots, so verify how many are free before ordering. This module is unbuffered, non-ECC and dual-rank 2Rx8, matching the platform's standard specification. JEDEC compliance ensures it meets the vendor's qualified parts list.

Green PCB with gold-edge contacts fits tight bays

No heat spreader keeps the profile low for the slim chassis, while the 204-pin edge connector seats firmly in the angled SODIMM socket. RoHS-compliant assembly avoids restricted substances. The stick installs tool-free by tilting into the slot until the side clips latch.
