Kingston Technology Corp. KTA-MB1066K2/4G 4GB (2 x 2GB) DDR3 1066 SO-DIMM memory upgrade

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.
