Mushkin Enhanced iRam 8GB (2 x 4GB) DDR3L 1866 SO-DIMM memory upgrade MAR3S186DM4G18X2

iMac Late 2015 memory kit

This dual-channel kit supplies two 204-pin SO-DIMM modules rated at DDR3L 1866 with CL13 timing and 1.35 V operation. The 8 GB total capacity is targeted at the 27-inch iMac models released in late 2015 that accept DDR3L memory. Mushkin Enhanced validates compatibility for the Core i5 and Core i7 configurations of that system. The modules carry no heat spreader and conform to the PC3L 14900 standard.

Suitable for compatible iMac upgrades

Owners of the specified 2015 iMac who want to add or replace memory with a tested dual-channel pair will find this kit appropriate. It is not intended for systems that require standard 1.5 V DDR3 modules. Builders working on Windows laptops or desktops that use different DDR generations should not use this product. The kit does not support platforms that demand higher speeds or alternative form factors.

DDR3L 1866 CL13 1.35 V specification

The decisive figure is the DDR3L 1866 speed grade combined with CL13 13-13-13-32 timings at 1.35 V. If the target iMac calls for this exact voltage and timing set, the kit matches the requirement. If the system needs a different voltage, speed or latency profile, this memory will not be compatible.
