• JEDEC and ROHS Compliance: Built to JEDEC specifications and ROHS compliant so the module meets standard interoperability and environmental safety expectations.
• Voltage and Stability: Operates at 1.2 volts as a non-registered, non-ECC module suitable for consumer desktops and laptops without server features.

Who It's For

This OWC 8GB memory module is ideal for owners of mid 2017 iMacs who want an affordable, warranty-supported way to improve multitasking, photo and video workflow responsiveness, and general system snappiness. It also suits laptop and all-in-one PC owners who need a single 8GB SO-DIMM module that matches PC19200 DDR4 2400MHz specifications.

Users who require error-correcting memory or registered ECC modules for server or workstation environments should look elsewhere, as this module is non-registered and non-ECC. Those seeking very high long-term reliability should weigh reports of occasional early failures against the lifetime replacement coverage before purchasing.
