While RAM cannot be upgraded after purchase, storage is also non-upgradeable. This guide covers complete MacBook Air M3 13-inch (2024) compatibility for upgrades.
RAM Compatibility for MacBook Air M3 13-inch (2024)
The MacBook Air M3 13-inch (2024) uses soldered LPDDR5 memory that cannot be upgraded after purchase. You must choose your RAM configuration at the time of ordering.
Memory Type: LPDDR5 (soldered to motherboard)
Stock Configuration: 8GB or 16GB unified memory

| Configuration | Memory | Total | Best For |
|---|---|---|---|
| Base config | 8GB LPDDR5 | 8GB | Basic tasks, web browsing |
| Upgraded config | 16GB LPDDR5 | 16GB | Productivity, moderate multitasking |
| Maximum config (BTO) | 24GB LPDDR5 | 24GB | Maximum performance, future-proofing |
Since RAM is soldered, choosing the right amount at purchase is critical. For general productivity and web browsing, 8GB is adequate.
