OWC 4 GB DDR3 1600 SO-DIMM for laptop and NAS

This module adds 4 GB of DDR3 memory to compatible laptops, all-in-one PCs and NAS units. It runs at 1600 MHz with CL11 latency and 1.5 V operation. The 204-pin unbuffered design matches the QNAP RAM-4GDR3-SO-1600 specification exactly.

Suits owners of DDR3 platforms needing a single 4

Buyers whose systems require a different memory generation cannot use this module because the physical notch and voltage differ. Systems that demand ECC or registered modules should look elsewhere, as this stick is non-ECC and unbuffered.

204-pin DDR3 SO-DIMM form factor decides fit

The 204-pin edge connector and DDR3 signalling determine whether the module seats correctly in the slot. Verify that the target device accepts 204-pin DDR3 SO-DIMMs before purchase.

Questions about this item

Does the 1.5 V DDR3 1600 module run hot or draw extra power during all-day use?

The stick is a standard 1.5 V unbuffered DDR3 1600 SODIMM with no heat spreader, so it operates at normal JEDEC voltage and thermal limits for continuous laptop or NAS workloads.

What must my system already provide for this 204-pin SODIMM to function?

Your laptop, mini PC or NAS needs a free DDR3 SO-DIMM slot that accepts 204-pin modules at 1.5 V and supports PC3-12800 CL11 timing.

Can I keep an existing DDR3 module of a different capacity in the second slot?

Yes — OWC recommends matching speed and voltage, so another 1.5 V DDR3 1600 stick of any capacity will work alongside this 4 GB module.
