Additional Notes
- The presence of 4 SO-DIMM slots implies a dual-channel architecture requiring identical pairs of modules to maintain peak memory bandwidth.
- High-capacity configurations reaching the 128 GB threshold necessitate the use of high-density 32 GB modules in every available slot.
- Upgrading the LENOVO ThinkPad P15 Gen 2 (15" Intel) requires access to internal slots located both beneath the keyboard and behind the base cover plate.
- Total memory latency is determined by the slowest module installed regardless of the 3200 MHz rating of the system board.
- Mixing single-rank and dual-rank modules across the 4 slots can lead to stability issues or automatic frequency downclocking by the BIOS.
- Physical clearance within the chassis restricts compatibility to standard height SO-DIMM modules and excludes those with integrated heat spreaders.
- Thermal dissipation requirements increase significantly when all 4 memory banks are populated with high-capacity modules during sustained workloads.
- Non-ECC and ECC modules are not compatible within the same system and must not be mixed to avoid boot failure.
