A-Tech 4GB DDR4 2133MHz SODIMM

This 4GB DDR4 module runs at 2133MHz with a 1.20V operating voltage. It uses a 260-pin SO-DIMM form factor and unbuffered, non-ECC architecture. The single-rank 1Rx8 design employs major brand chips for reliable operation in compatible Apple systems.

Suits 21.5-inch iMac Mid 2017 model A1418 EMC 3068

This upgrade fits the iMac18,1 system ID and Apple order number MMQA2LL/A. Buyers with different iMac screen sizes, different release years, or Apple Silicon systems cannot use this module because the physical and electrical interfaces differ. Those needing higher capacity than 4GB should look elsewhere.

DDR4 2133MHz PC4-17000 260-pin SO-DIMM specification

The memory speed rating of DDR4 2133 (PC4-17000) combined with the 260-pin SO-DIMM form factor determines whether this part will install and function. Verify your system requires exactly this speed and pin count before ordering, as other DDR generations or pin layouts are physically incompatible.

أسئلة حول هذا المنتج

Does this DDR4 2133 MHz SODIMM need a free 260-pin slot in my iMac 21.5 Mid 2017?

Yes, the module uses the standard 260-pin SO-DIMM form factor and installs in an available memory slot on the iMac18,1 logic board.

Will this 4 GB PC4-17000 stick run at the correct speed alongside any existing 2133 MHz DDR4 modules?

The system will operate all installed DDR4 memory at 2133 MHz, so this 1Rx8 unbuffered module matches the native speed of the Mid 2017 iMac.

How can I confirm the new 4 GB module is recognised after installation?

Open About This Mac or System Report; the memory section should show the additional 4 GB DDR4 2133 MHz SO-DIMM and the updated total capacity.
