System-specific memory for 2015 iMac

This 32 GB kit (4 x 8 GB) is built for the Apple iMac "Core i7" 4.0 27-Inch (5K, Late 2015). It uses 204-pin DDR3L SO-DIMM modules rated at 1866 MHz (PC3L-14900) with CL13 timing and 1.35 V operation. The unbuffered, non-ECC design matches the factory specification for this all-in-one desktop.

Fits four SO-DIMM slots directly

The iMac 27-inch (Late 2015) provides four memory sockets accessible behind a rear door. This kit fills all four slots to reach the 32 GB maximum supported by the system. No heat spreaders are included, keeping module height low for the tight internal clearance. Installation requires no tools beyond the door latch.

Sustained load stability

DDR3L voltage reduces heat output during extended workloads compared to standard DDR3. Major-brand DRAM chips and 2Rx8 organisation deliver consistent throughput for long rendering, virtualisation or multi-tab sessions. The CL13 13-13-13 timing maintains low latency without relying on aggressive profiles that can destabilise under thermal pressure.

商品問答

What is the CAS latency of the CM10246414900SODRL modules under sustained load?

The modules run at CL13 with 13-13-13 timings, so the column-access delay stays at 13 cycles during continuous operation.

How much power and heat do the four 1.35 V DDR3L sticks generate when the iMac runs all day?

Each stick operates at 1.35 V without a heat spreader; the kit draws standard DDR3L power and relies on the iMac’s internal airflow for cooling.

Which iMac model must I already own for this 4 x 8 GB kit to work?

This kit is validated for the Apple iMac "Core i7" 4.0 27-Inch (5K, Late 2015) — model identifiers iMac17,1 and A1419.
