OWC 4GB DDR3-1066 SODIMM modulo di memoria RAM per Mac

Mac systems often ship with minimal memory, leading to sluggish performance when running multiple applications or modern macOS versions. This OWC 4GB DDR3-1066 SODIMM module directly addresses that bottleneck, giving your compatible MacBook, MacBook Pro, iMac, or Mac mini the headroom it needs for smoother multitasking, faster app launches, and a more responsive overall experience.

Who is it for

This memory upgrade is ideal for Mac users who push their machines daily—creative professionals working with large files, students juggling research and media, or anyone tired of the spinning beach ball. It is also a practical choice for IT administrators maintaining fleets of older Macs, as well as owners of small form factor PCs and laptops that accept 204-pin DDR3 SODIMMs.

Main features

• 4GB capacity doubles or quadruples the memory in many original configurations, enabling more applications to run simultaneously.
• DDR3-1066 (PC3-8500) speed matches the memory controller of supported Macs for stable, error-free operation.
• 204-pin SODIMM form factor fits the compact memory slots found in notebooks and small desktops.
• Non-ECC, unbuffered design meets the requirements of consumer and professional Mac systems.
• Low 1.5V operating voltage helps reduce power consumption and heat generation, extending battery life in portable Macs.
• Dual-rank architecture (2Rx8) ensures broad compatibility with a wide range of chipsets and memory controllers.
• RoHS compliant and lead-free construction supports environmentally responsible disposal and recycling.

Tips

Before purchasing, verify your Mac's exact model and year to confirm DDR3 1066MHz SODIMM support. Installation is straightforward: shut down, remove the bottom case or memory door, insert the module at a 30-degree angle, and press down until it clicks. For best performance, install in matched pairs if your system supports dual-channel memory.
