Apple notebook DDR3 upgrade

This 4 GB kit uses two 2 GB SO-DIMM modules built to the 204-pin DDR3 1066 standard. It is designed for Apple notebooks that accept PC3 8500 memory running at 1.5 V with CL7 timing. The dual-channel configuration helps the memory controller move data more efficiently.

Replaces slower or smaller DDR3 SO-DIMMs

If the notebook currently runs a single module or lower-speed DDR3, this kit restores dual-channel bandwidth and raises the clock to 1066 MHz. The jump is worth it when the system board supports PC3 8500 and the original memory operates at a lower frequency or higher latency.

Suits owners of compatible Apple notebooks needing

Buyers who want more storage or a newer DDR generation should look elsewhere because this product is fixed at DDR3 1066 and 4 GB total capacity. Systems that require 204-pin DDR3 at 1.5 V with 7-7-7-20 timing will install and run without changes.

Spørgsmål om denne vare

Does the 204-pin DDR3 SO-DIMM form factor fit the memory slots in my Apple notebook?

Yes, each module uses the standard 204-pin DDR3 SO-DIMM layout that matches the slots used in compatible Apple notebooks.

What is the correct way to seat both sticks so the dual-channel kit runs at DDR3 1066 with 7-7-7-20 timings?

Insert each stick at the same angle, press down firmly until the side clips click on both modules, then verify the speed and timings in the system profiler.

When should I expect to replace these 1.5 V DDR3 modules in a typical laptop?

DDR3 SO-DIMMs have no moving parts and generally last the usable life of the notebook; replacement is only needed if a module fails or you upgrade capacity.
