Target Mac Models

This 8 GB kit contains two 4 GB DDR3L 1600 SODIMM modules built for specific Apple computers. It fits MacBook Pro 13 inch and 15 inch Mid 2012, iMac 21.5 inch and 27 inch Late 2012 through Mid 2015, and Mac mini Late 2012.

Sustained Workload Behaviour

The modules run at 1.35 V without ECC or buffering, using major-brand chips in a 2Rx8 layout. Under continuous load they maintain the rated PC3-12800 bandwidth because the low-voltage DDR3L design keeps power draw and heat within the original thermal envelope of the supported Macs.

Installation Notes

Each stick is a standard 204-pin SODIMM with no heat spreader, so it slides directly into the factory memory slots. The only common issue is mixing these sticks with existing modules of different speed or voltage, which can prevent the system from booting or force it to run at the lower common specification.

Questions about this item

Does the 1.35V DDR3L 1600 kit run cooler than standard DDR3 in a 2012 MacBook Pro?

The 1.35V DDR3L modules draw less power than 1.5V DDR3, producing less heat and no audible noise during all-day use.

Will these 204-pin SODIMMs install directly into the stock slots of a Late 2012 Mac mini without extra tools?

Yes, the 204-pin SODIMM form factor matches the factory memory slots on the Late 2012 Mac mini for tool-free installation.

Can I mix this 2Rx8 PC3-12800 kit with the original 4GB modules in a Mid 2012 MacBook Pro?

The 2Rx8 1600MHz modules are compatible with the Mid 2012 MacBook Pro and will run at the system's supported speed alongside existing memory.
