Computer Memory Solutions 32GB (4x8GB) DDR3L 1600 SODIMM for iMac 27 2013

SKU CH-TCK0-5P24W

Four 8 GB DDR3L 1600 SODIMM modules add 32 GB to the late 2013 27-inch iMac

  • Rated speedDDR3L 1600 (PC3L 12800)
  • ChipsetMajor Brand Chipset
  • CAS latencyCL11
  • Memory timings11-11-11
  • Rated voltage1.35 V
  • 32 GB kit fills all four slots on the 27-inch 2013 iMac
  • DDR3L 1600 MHz speed matches the original specification
  • Low 1.35 V operation reduces heat and power draw
  • CL11 latency keeps response times tight
  • 204-pin SODIMM form factor fits the iMac memory bay exactly

Targeted Upgrade

This 32 GB kit contains four 8 GB DDR3L SODIMM modules built for the Apple iMac 27-inch Late 2013 with the 3.5 GHz Core i7. It fills all four memory slots to reach the system maximum of 32 GB. Buyers who need ECC error correction or registered modules should look elsewhere.

Low Voltage Operation

Each module runs at 1.35 V, the standard DDR3L voltage, keeping power draw and heat output modest inside the compact all-in-one chassis. Unbuffered 2Rx8 organisation and CL11 timings at 1600 MHz deliver stable performance without active cooling. Systems limited to 1.5 V DDR3 or requiring higher density per slot cannot use this kit.

Sustained Workload Behaviour

Under continuous load the memory maintains its rated 1600 MHz speed and 11-11-11 timings without throttling, as the low voltage and lack of heat spreaders suit the iMac’s internal airflow. Workloads that demand capacities beyond 32 GB or quad-channel bandwidth will not benefit from this upgrade.

Questions about this item

How do I install the 4 SODIMM modules into the 27‑inch iMac and which step do people skip?

Remove the power cord, open the memory door at the bottom, release the two clips on each slot, align the notch on the 204‑pin module, press firmly until both clips click, repeat for all four slots, then close the door and reconnect power.

What maintenance or replacement will this 32GB kit need later?

The modules are unbuffered, non‑ECC DDR3L parts with no heat spreader; they require no routine maintenance, but if a stick fails it must be replaced with another 1.35V DDR3L 1600MHz 2Rx8 SODIMM to keep the set matched.

What limit appears first during sustained heavy workloads on this 1600MHz CL11 kit?

The 1600MHz data rate and CL11 latency set the bandwidth ceiling, so memory throughput saturates before the CPU or storage in long renders or virtual‑machine workloads.
