Additional Notes
- Dual channel mode is only achieved when matching modules are installed in both slots to optimize memory bandwidth.
- The maximum capacity limits single slot modules to 16 GB per socket for the Dell Inspiron 5405 hardware configuration.
- Installing memory with higher clock speeds will result in downclocking to the system bus limit of 3200 MHz.
- Physical access to the SO-DIMM slots requires the removal of the base cover and likely the disconnection of the internal battery to prevent electrical short circuits.
- Mixing modules with different CAS latencies will force the system to operate at the timing of the slower module.
- Non-ECC unbuffered memory is the only supported architecture for stable operation within this platform.
- Integrated graphics performance scales directly with the speed and quantity of available system memory because the GPU lacks dedicated VRAM.
