Apple notebook memory upgrade

This 1GB DDR2 667 SO-DIMM module is built specifically for compatible MacBook and MacBook Pro models released before October 2008. It uses a 200-pin form factor and operates at 1.8V with CAS latency 5 timing.

Lifetime guarantee and live support

The supplier backs this module with a lifetime guarantee and provides live technical support for installation or troubleshooting. These services replace the typical limited warranty period and give direct access to assistance if compatibility questions arise.

1GB capacity for legacy macOS

A single 1GB stick suits period-correct macOS versions and everyday applications from that era. It will not meet the memory requirements of later operating systems or modern multitasking workloads that demand several gigabytes.

Questions about this item

Will the 1.8V DDR2 SO-DIMM need replacement due to wear over time?

No — DDR2 memory has no moving parts and no write-cycle limit, so the module itself does not wear out; only physical damage or a motherboard failure would require replacement.

What limit appears first when the MacBook runs the 5-5-5-15 timings continuously?

The DDR2-667 bus bandwidth and CAS 5 latency are the fixed bottlenecks; sustained workloads cannot exceed the 5300 MB/s theoretical throughput of the PC2-5300 module.

How much heat and power does the 1GB stick produce without a heat spreader during all-day use?

At 1.8 V the module draws only a few watts and runs cool enough that passive airflow inside the MacBook case is sufficient — no extra cooling or noise is generated.
