ACER Nitro N515-55-78CW RAM upgrade specifications
The ACER Nitro 5 series model N515-55-78CW features two SO-DIMM memory slots supporting DDR4-SDRAM upgrade specifications. Compatible RAM modules operate at 2933 MHz frequency with maximum capacity of 32 GB total memory. The laptop supports RAM upgrades through dual SO-DIMM slots, allowing users to expand system memory up to the specified maximum capacity. Upgrade specifications include DDR4 memory type with SO-DIMM form factor for compatible module installation.

Additional Notes
- The Acer Nitro N515-55-78CW supports DDR4-SDRAM modules exclusively; DDR5 memory remains incompatible despite availability in newer systems, restricting upgrade sources to legacy inventory or secondary markets.
- Dual SO-DIMM slots mean both memory modules must be replaced simultaneously to reach the 32 GB ceiling; single-module upgrades cap at 16 GB and forfeit dual-channel bandwidth benefits.
- The 2933 MHz frequency specification indicates the system controller's rated speed ceiling; matched pairs operating at this frequency are required to prevent speed negotiation downgrades when mixed with slower modules.
- SO-DIMM form factor demands laptop-specific modules rather than desktop DDR4 variants, creating higher per-gigabyte costs and requiring vendor verification before purchase to avoid return logistics.
- Upgrading from factory configuration to 32 GB removes the last accessible user-serviceable memory component; subsequent capacity expansion becomes impossible without motherboard replacement.
- The 2-slot architecture eliminates redundancy; a single module failure leaves no fallback configuration and forces complete replacement rather than selective module repair.
