Mac notebook memory upgrade

This Crucial CT8G3S1339M module adds 8GB of DDR3 memory to compatible Apple notebooks. It runs at 1333 MT/s with a CAS latency of 9 and operates at 1.35V or 1.5V. The 204-pin SO-DIMM form factor fits the memory slots used in these specific Mac systems.

Fits Apple notebook slots

The module installs directly into a 204-pin SO-DIMM socket inside the notebook. No additional cables, brackets or power connections are required. Adding this memory frees the system from relying on slower storage for virtual memory during multitasking.

Suits owners of compatible Macs

This upgrade suits Mac users whose notebooks accept DDR3 1333 SO-DIMMs and have an available slot. Buyers who need a different memory generation, a higher speed grade, or a DIMM form factor for a desktop should look elsewhere.

商品問答

Does the 1.35V operating voltage limit heat output during all-day use?

The module runs at 1.35V or 1.5V, so power draw and heat stay low even under continuous load.

Will the CL9 latency at 1333 MT/s create a bottleneck in sustained workloads?

CL9 at 1333 MT/s is the rated timing; the limit you hit first is the bus speed itself, not the latency.

Does my Mac need a 204-pin DDR3 slot to accept this module?

Yes — it is a 204-pin DDR3 SO-DIMM built for Apple notebooks that use DDR3 memory.
