32GB DDR3L kit for 27-inch iMac 2015

This 32GB kit contains four 8GB modules built to the DDR3L 1866 specification. The modules are 204-pin SO-DIMMs rated at CL13 with 1.35V operation and are validated for the Apple iMac Retina 5K 27-inch Late 2015 model MK472LL/A.

Unbuffered 2Rx8 chips sustain CL13 timing under load

Unbuffered 2Rx8 chips maintain the specified CL13 timing at 1866 MHz without registered buffering overhead. The 1.35V DDR3L voltage keeps power draw low during sustained workloads in the iMac's compact thermal envelope.

Verify four-slot 64GB maximum before ordering

The iMac uses four SO-DIMM slots with a 64GB total limit, so this 32GB kit occupies all slots and leaves no room for further expansion. Buyers needing more than 32GB must replace the entire set rather than add modules.

Questions about this item

How much power do the 1.35 V DDR3L modules draw when the iMac runs all day?

Each SO-DIMM operates at 1.35 V, the standard low-voltage level for DDR3L, so total draw stays within the iMac’s original thermal envelope.

What must the iMac already have for this 4×8 GB kit to work?

The Late 2015 27-inch Retina 5K iMac (MK472LL/A) with four empty 204-pin SO-DIMM slots, supporting up to 64 GB total.

Will the CL13 1866 MHz sticks run stably alongside the original Apple memory if I keep two slots?

Yes, the kit matches the factory DDR3L 1866 CL13 specification, so mixed populations run at the common 1866 MHz speed without timing conflicts.
