System-Specific DDR3 SO-DIMM

This 4 GB DDR3 1333 MHz SO-DIMM is built for Apple iMac 21.5-inch models with a 2.5 GHz Core i5 processor. It uses a 204-pin unbuffered non-ECC layout and runs at 1.5 V with CL7 timing. The module is validated for the MC309LL/A system identifier.

Steady-State Memory Behaviour

Major-brand chips and a 2Rx8 organisation keep data rates stable during extended workloads such as video rendering or large dataset processing. The CL7 7-7-7 timing profile maintains low latency without relying on aggressive voltage scaling, so throughput stays consistent when the system is under continuous pressure.

Mechanical Fit and Daily Use

A bare green PCB without a heat spreader slides cleanly into the iMac’s SO-DIMM slots, avoiding clearance issues with the factory cooling shroud. The single-stick packaging lets owners populate one of four sockets now and add matching modules later up to the 32 GB physical limit noted for compatible 21.5-inch and 27-inch models.

أسئلة حول هذا المنتج

How much power does the 1.5 V DDR3 SO-DIMM draw when the iMac runs all day?

Standard DDR3 SO-DIMMs at 1.5 V typically consume a few watts under load; the module itself has no heat spreader and adds minimal heat to the iMac's internal airflow.

Does the 204-pin DDR3 1333 MHz module need any other parts to work in my iMac 21.5-inch 2.5 GHz Core i5?

No extra parts are required; the SO-DIMM installs directly into one of the four memory slots inside the iMac.

Can I keep the original Apple memory and add this 4 GB stick to reach 16 GB or the 32 GB maximum?

Yes, the iMac has four slots and supports up to 32 GB; you can mix this 4 GB module with existing sticks as long as the total does not exceed 32 GB.
