4GB DDR3L SODIMM for Laptop and NAS

This 4GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V operation. It uses a 204-pin SO-DIMM form factor suitable for laptops, all-in-one systems and NAS devices. The unbuffered, non-ECC design matches standard consumer memory requirements. OWC validates each module to meet JEDEC and RoHS compliance.

Check 204-pin DDR3L slot and voltage

Verify that your system accepts 204-pin DDR3L SO-DIMM modules before ordering. The board must support 1.35V low-voltage operation; 1.5V DDR3 slots may not be compatible. Confirm the memory controller handles PC3L-12800 speed and CL11 timing. This module is single-rank 1Rx8 organisation and contains no heat spreader.

Replaces specific NCR part numbers

The module directly replaces NCR part numbers 497-0505658, 497-0519222, 7702-K134, 7761-K130 and 7761-K132. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme. No additional software or cables are included in the package. Installation follows standard SO-DIMM insertion steps.
