iMac 27-inch 2019–2020 memory kit

This 128 GB kit contains four 32 GB DDR4 2666 MHz SO-DIMM modules built for the 27-inch iMac models identified as 19,1, 20,1 and 20,2. The unbuffered non-ECC memory runs at 1.2 V with CL19 timing and uses 260-pin dual-rank chips. It is supplied new and ready to install in the four available slots.

Suits owners of the listed iMacs wanting maximum

The kit fills all four slots on the 27-inch Mid 2019 and Mid 2020 Retina 5K iMacs, delivering the full 128 GB those machines accept. Builders working on Mac mini Late 2018 or any other system with only two slots should look elsewhere because this package provides four modules. Users needing ECC or registered memory will not find those features here.

260-pin DDR4 SO-DIMM form factor

Each module measures 30 mm high by 69.6 mm long and conforms to the PC4-21300/PC4-21333 standard. The 260-pin edge connector and 1.2 V operation match the electrical and mechanical requirements of the compatible iMac models. Verify your model identifier before purchase to ensure the modules will seat correctly.

商品問答

Should I pick the 128GB kit or a smaller capacity for my 27-inch iMac?

The 128GB kit fills all four slots with 32GB modules. Choose it if your iMac 19,1, 20,1 or 20,2 supports the maximum. Smaller kits leave slots free for later expansion.

What does the 2666MHz rating deliver once installed in a compatible iMac?

The modules run at 2666MHz with CL19 latency at 1.2V, matching the PC4-21300/PC4-21333 specification the iMac memory controller expects.

Does the 260-pin SO-DIMM interface limit speed or capacity in these iMacs?

The 260-pin DDR4 SO-DIMM form factor is the native slot type for the listed 2019 and 2020 27-inch iMacs, so it imposes no extra limit beyond the 2666MHz rating.
