Check Your System First

Verify that the target machine uses DDR2 SO-DIMM slots and supports PC2-5300 speed at 1.8 V. The motherboard must accept 200-pin modules and operate without ECC or registered memory. Consult the device manual or vendor documentation to confirm the maximum capacity per slot and total system limit before ordering.

The module meets JEDEC standard specifications and is ROHS compliant, making it a warranty-safe upgrade for OEM systems. OWC tests every stick in-house and backs it with a limited lifetime warranty and free technical support. No extra software, heat spreaders or cables are included in the package.
