Additional Notes
- The ASUS Zenbook UX561UD-E2008T contains soldered memory on the motherboard paired with a single user-accessible SO-DIMM slot, meaning RAM expansion capacity is constrained by the fixed on-board allocation rather than the theoretical 24 GB maximum being freely distributable across slots.
- DDR4-2400 MHz memory operates at a frequency tier below contemporary standards (2666 MHz and higher became common after 2017), which establishes a performance ceiling for the system bus and may reduce bandwidth efficiency when paired with newer DDR4 modules rated for higher speeds.
- A single SO-DIMM slot eliminates the possibility of dual-channel memory configuration through user upgrades, constraining memory bandwidth to single-channel operation unless the on-board memory component supports dual-channel pairing with the SO-DIMM independently.
- Installing a SO-DIMM module rated above 2400 MHz will operate at the downclocked 2400 MHz frequency due to BIOS and memory controller specifications, making higher-frequency modules provide no performance benefit while increasing cost unnecessarily.
- The 24 GB maximum capacity suggests approximately 8 GB soldered on-board, leaving 16 GB as the practical SO-DIMM upgrade ceiling; exceeding this results in non-bootable configurations or system instability.
- SO-DIMM replacement requires partial system disassembly and carries warranty implications depending on manufacturer policy; documenting the existing memory configuration before removal protects against accidental incompatibility claims.
