ASUS Vivobook X512UA-EJ497T RAM upgrade specifications

ASUS Vivobook Series 15 model X512UA-EJ497T features DDR4-SDRAM memory with one SO-DIMM slot available for upgrade. The laptop includes onboard memory soldered to the motherboard plus one expandable SO-DIMM slot. Maximum compatible RAM capacity reaches 12 GB total. Memory operates at 2400 MHz frequency. Upgrade specifications allow installation of compatible DDR4 modules in the available slot to increase system memory capacity beyond factory configuration.

Additional Notes

• The ASUS Vivobook X512UA-EJ497T contains soldered memory on the motherboard, meaning only the single SO-DIMM slot is upgradeable; the on-board portion cannot be replaced or removed.
• Maximum addressable RAM of 12 GB indicates 8 GB soldered memory paired with a 4 GB SO-DIMM module, creating an asymmetrical memory configuration that reduces dual-channel performance benefits.
• DDR4-2400 MHz specification locks the system to older DDR4 standards; newer DDR4-3200 or DDR4-3600 modules will downclock to 2400 MHz, providing no performance advantage and potentially causing compatibility warnings in BIOS.
• The single SO-DIMM slot eliminates redundancy; failure of the replaceable module or its socket leaves the system with only soldered memory capacity, reducing total usable RAM to 8 GB.
• Upgrading to the maximum 4 GB SO-DIMM maintains the 8+4 GB split, preventing symmetric dual-channel operation that would optimize bandwidth for both processor and integrated graphics.
• SO-DIMM availability at DDR4-2400 is declining in retail markets; sourcing a compatible module may require surplus inventory or refurbished channels rather than current-generation stock.
• Installing any SO-DIMM module requires disassembly of the laptop base; most ASUS Vivobook models require removal of the keyboard or bottom panel, presenting warranty concerns unless performed by authorized service centers.
