Apple Notebook DDR3 Kit

This kit supplies 4 GB of DDR3 memory in two 2 GB SO-DIMM modules built for Apple notebooks. Each stick runs at 1066 MHz with a CAS latency of 7 and operates at the standard 1.5 V. The 204-pin form factor matches the slots used in compatible Mac models. It is a straightforward capacity upgrade for owners of those machines.

Dual-Channel 204-Pin Upgrade

Installing the pair activates dual-channel mode on supported logic boards, which increases memory bandwidth without requiring extra slots. The modules need no heat spreader and draw power only from the SO-DIMM socket. Builders simply insert both sticks into the available memory bays, freeing no other resources and demanding no additional cables or cooling.

Sustained 1.5 V Operation

Under continuous workloads the memory maintains its rated 1066 MHz speed at the specified 1.5 V. The absence of a heat spreader means the modules rely on the notebook's internal airflow, which is adequate for the low-power DDR3 design. Stability is preserved through Kingston's validation process, delivering 100 percent compatibility with the target Apple systems during extended use.

Questions about this item

Does the 1.5 V DDR3 1066 kit throttle under sustained load without a heat spreader?

The modules run at standard 1.5 V with CAS 7 latency and no heat spreader; thermal throttling is not typical for DDR3 1066 SO-DIMM workloads.

How much heat or noise does the 204-pin DDR3 1066 kit add when running all day?

Memory modules produce negligible heat and zero audible noise; system fan speed is unchanged by this 1.5 V kit.

Which Apple notebook models accept this 204-pin DDR3 1066 SO-DIMM kit?

Compatibility is limited to Apple notebooks that use 204-pin DDR3 1066 (PC3 8500) SO-DIMM slots; verify your model before purchase.
