Compatible upgrade kit for DDR2 laptops
This OWC kit supplies two 2 GB DDR2 533 SO-DIMM modules for a total of 4 GB. It targets owners of older laptops, all-in-one PCs or compatible NAS units that accept 200-pin PC2-4200 memory. The dual-channel pair is designed to match factory specifications for a straightforward capacity increase.
Verify slot count and maximum supported memory
Before ordering, confirm that your system uses 200-pin DDR2 SO-DIMM slots and can address 4 GB in total. Check the manufacturer documentation for the maximum capacity per slot and whether the BIOS requires matched pairs. The modules run at 1.8 V with CL4 latency and are unbuffered, non-ECC parts.
JEDEC-compliant modules with lifetime support
Each stick is tested to meet JEDEC and RoHS standards, ensuring a warranty-safe upgrade without voltage or timing surprises. OWC backs the kit with a limited lifetime warranty and free technical support, while the dual-channel configuration helps the memory controller operate at its rated bandwidth. No heat spreaders or extra software are included.
