Compatible iMac memory upgrade

This 16 GB kit contains two 8 GB DDR3L SO-DIMM modules rated at 1600 MHz and 1.35 V. It is built specifically for the Apple iMac Core i7 3.5 27-Inch Late 2013 model MF125LL/A. The unbuffered non-ECC sticks use a 204-pin layout and carry CL11 11-11-11 timings. Computer Memory Solutions validates compatibility for this system.

Suits Late 2013 27-inch iMac owners

The kit matches the factory slot count and maximum capacity for the named iMac. Buyers with other iMac models or non-Apple laptops should verify their exact memory specifications before purchasing. Systems requiring ECC registered modules or a different pin count cannot use this memory. The absence of a heat spreader may limit overclocking headroom.

1600 MHz DDR3L speed rating

The decisive specification is the DDR3L 1600 (PC3L 12800) operating frequency at 1.35 V. The target iMac must support this speed and voltage combination for the modules to function at their rated performance. If the platform only accepts a lower DDR3 speed grade the kit will not run as intended.

Questions about this item

Should I buy the 16GB kit as two 8GB modules or look for a single 16GB stick?

This kit provides exactly 16GB as two 8GB SO-DIMMs, matching the iMac's two memory slots for full dual-channel operation.

What does the 1600MHz speed actually deliver inside my Late 2013 iMac?

The modules run at DDR3L 1600 (PC3L 12800) with CL11 timing at 1.35V, the exact specification Apple requires for that model.

Will the 204-pin DDR3L interface work without voltage issues in my iMac?

Yes, these are 1.35V DDR3L SO-DIMMs, the correct low-voltage standard for the Late 2013 27-inch iMac.
