Additional Notes
- The presence of 2 SO-DIMM slots allows for a dual-channel memory configuration which doubles the theoretical bandwidth compared to single-channel setups.
- Hardware limitations on the Lenovo Yoga S740 motherboard restrict the addressable memory capacity to 16 GB despite the physical ability to install larger capacity modules.
- Installing memory modules with higher frequency ratings will result in an automatic downclocking to match the 2666 MHz system bus limitation.
- Physical access to the memory slots requires the removal of the bottom chassis cover which may involve internal clips and captive screws.
- Syncing latency timings between both slots is necessary to maintain system stability and prevent boot failures during POST.
- The maximum capacity threshold indicates that high-density 16 GB single sticks are incompatible if used in pairs.
- Upgrading requires standard 260-pin DDR4 modules as older DDR3 or newer DDR5 variants are physically keyed differently and will not fit the slots.
