4GB DDR3L 1866 Desktop Module

This 4GB DDR3L module runs at 1866MHz with a PC3L-14900 rating. It fits standard 240-pin DIMM slots and operates at 1.35V low voltage. The unbuffered, non-ECC design targets mainstream desktop upgrades.

DDR3L voltage and speed limits

DDR3L memory is specified at 1.35V, lower than standard DDR3, so the motherboard must support this voltage for correct operation. The 1866MHz tested frequency will only be reached if the platform memory controller and BIOS allow that speed. Systems limited to lower DDR3 speeds will downclock the module automatically.

Single-rank unbuffered build

The 1Rx8 single-rank organisation keeps electrical loading light on the memory controller. Gold-plated 240-pin edge connectors resist oxidation for reliable seating over repeated installs. As an unbuffered DIMM it installs directly without registered buffers, suiting typical consumer desktop boards.
