Additional Notes
- The presence of on-board memory dictates that total capacity increases are limited by a single physical expansion slot despite the reported logic for 3 slots.
- The asymmetrical memory configuration causes the system to operate in flex mode where dual-channel bandwidth only applies to the capacity that matches the soldered module.
- Installing a module with a frequency higher than 2666 MHz results in automatic downclocking to match the hardwired speed of the integrated memory bank.
- The Asus ROG GX531GX-ES002T requires low-voltage SO-DIMM modules to ensure thermal stability within the ultra-slim chassis design.
- Physical access to the expansion slot requires the removal of the bottom panel which may involve proprietary screws or delicate ribbon cables connected to the Active Aerodynamic System.
- Latency timings will default to the highest common denominator between the permanent on-board chips and the added removable stick.
- Total addressable memory is capped at 24 GB because the integrated component cannot be swapped or disabled to accommodate larger density pairings.
