Additional Notes
- The 2x SO-DIMM configuration permits dual-channel memory operation when identical modules are installed in both slots, doubling theoretical bandwidth compared to single-channel mode.
- The 32 GB maximum capacity requires 2x16 GB modules, leaving no slots available for future expansion without replacing existing memory.
- DDR4-2666 represents the highest JEDEC-standard speed supported by the system's memory controller; faster modules will downclock to 2666 MHz.
- SO-DIMM form factor modules measure 67.6mm in length, distinguishing them from desktop DIMM modules which are physically incompatible with this laptop.
- Memory installed must operate at 1.2V standard DDR4 voltage; low-voltage DDR3L or DDR3 modules are electrically and physically incompatible despite similar physical dimensions.
- Single-slot population with one module will halve memory bandwidth by forcing single-channel operation, potentially reducing integrated graphics performance by 20-30 percent.
- Memory configuration changes typically do not void manufacturer warranty, as RAM slots are designed for user-accessible upgrades without requiring technician disassembly of sealed components.
- Mixed-capacity configurations (8 GB + 16 GB) will operate but may force flex-mode operation where only the matched portion runs in dual-channel, with the remainder in single-channel.
- The DDR4-SDRAM specification excludes compatibility with DDR5, DDR3, or earlier generation memory technologies due to different keying notches and electrical signaling.
- CAS latency ratings (CL17, CL19, CL22) affect real-world responsiveness, with lower values providing marginally better performance at identical frequencies.
