NEMIX RAM 4GB DDR3 1866 SODIMM

This 4GB DDR3 SODIMM module runs at 1866MHz with CL13 latency and 1.35V operation. It uses a 204-pin form factor and 1Rx8 rank configuration. The non-ECC unbuffered design targets Synology NAS systems requiring PC3-14900 memory.

Synology NAS owners adding memory

The module fits Synology devices that accept DDR3 1866 SODIMM RAM. Buyers needing ECC error correction or registered modules should look elsewhere. Systems requiring higher capacity per slot or different voltage specifications will not be compatible.

PC3-14900 speed rating decides fit

The 1866MHz DDR3 speed grade determines whether this module matches the system memory bus. Verify the NAS motherboard supports PC3-14900 before purchase. Incorrect speed selection prevents boot or forces downclocking.

Questions about this item

Will this 204-pin DDR3 SODIMM fit my Synology NAS that currently uses a single memory slot?

Yes, the module is a 204-pin DDR3 SODIMM designed for Synology systems that accept this form factor and voltage.

Can I install this 1.35 V DDR3 1866 module alongside an existing 1.5 V DDR3 stick in the same NAS?

The stick operates at 1.35 V; mixing voltages is not recommended because the system will default to the higher voltage.

How can I confirm the NAS recognises the full 4 GB at DDR3 1866 CL13 after installation?

Check the DSM Resource Monitor or memory information page; it should show 4 GB running at 1866 MHz with CL13 timings.
