ACER Nitro AN515-55-745W RAM upgrade specifications

The ACER Nitro 5 series model AN515-55-745W supports DDR4-SDRAM memory upgrades with maximum capacity of 32 GB. The laptop features 2x SO-DIMM memory slots for RAM expansion. Compatible memory modules operate at 2933 MHz frequency. Upgrade specifications enable users to enhance system performance through compatible DDR4 SO-DIMM modules, with total memory capacity reaching 32 GB maximum across available slots.

Additional Notes

• The Acer Nitro AN515-55-745W accepts dual-channel memory configurations, enabling symmetric bandwidth distribution when both SO-DIMM slots contain identical capacity modules.
• DDR4-2933 represents the maximum validated frequency for this platform, while higher-speed modules will function through automatic downclocking to specification limits.
• Configurations exceeding 16 GB require both SO-DIMM slots to be populated, as single-slot installations are limited to half the advertised system maximum.
• The SO-DIMM form factor designation excludes standard desktop DIMM modules, which are physically incompatible with the 260-pin mobile memory interface.
• Mixing modules with different frequencies will force both sticks to operate at the slower module's rated speed, eliminating the performance advantage of the faster component.
• Asymmetric capacity configurations (such as 8 GB paired with 16 GB) will operate in flex mode, delivering dual-channel bandwidth only up to the capacity threshold of the smaller module.
• Non-volatile memory (such as Optane) occupies separate M.2 storage channels and does not consume or conflict with SO-DIMM memory expansion resources.
• Modules exceeding JEDEC voltage specifications (1.2V for DDR4) may trigger thermal throttling in thermally constrained mobile chassis designs.
• CAS latency variations between matched-frequency modules will default to the higher latency timing, marginally affecting memory access response times.
• User-accessible memory compartments typically preserve warranty coverage, whereas soldered or factory-sealed configurations would prohibit field upgrades entirely.
