Additional Notes

  • The presence of on-board memory means a portion of the system RAM is non-removable and soldered directly to the motherboard.
  • Dual-channel memory performance depends on matching the capacity of the single SO-DIMM slot with the existing soldered module.
  • The maximum capacity limit of 32 GB suggests that the total addressable memory is constrained by the motherboard firmware despite the physical ability of 16 GB or 32 GB modules to fit the slot.
  • Upgrading the ASUS ROG Zephyrus Duo 15 SE GX551QM-HF052T requires a single DDR4 module to reach the peak supported configuration.
  • Installing a module with a frequency higher than 3200 MHz will result in downclocking to the native speed of the soldered memory controller.
  • Total system latency is determined by the slowest timings between the permanent on-board memory and the user-installed SO-DIMM.
  • Physical access to the expansion slot necessitates the removal of the bottom chassis cover which may involve bypassing factory seals on specific screws.
  • Asymmetrical memory configurations exceeding the soldered capacity will operate in Flex Mode where only a portion of the RAM runs at full dual-channel bandwidth.
