Apple Notebook DDR2 800 kit

This Mushkin Enhanced 976577A kit supplies 4 GB of DDR2 memory in two 2 GB modules. The 200-pin SO-DIMMs run at 800 MT/s with CAS latency 5 and 1.8 V. It is built as a dual-channel kit for Apple notebooks that accept DDR2 800 SO-DIMM memory.

Owners of compatible Apple notebooks

The kit suits users whose Apple notebook requires 200-pin DDR2 800 SO-DIMMs and has two slots available. Buyers whose machine uses a different DDR generation, a different pin count, or only a single slot should look elsewhere.

Dual-channel 2 x 2 GB configuration

The memory is sold as a matched pair of 2 GB modules, giving 4 GB total in dual-channel mode. This configuration is the deciding factor for systems that need paired modules to reach full bandwidth.
