  • Ensure the memory modules are fully seated in their slots. Remove and reinsert them firmly.
  • Verify that the notches on the modules align correctly with the slots.
  • Check your laptop's manual for specific memory configuration requirements (e.g., specific slots for single modules).
• Incorrect Memory Amount Detected:
  • Repeat the steps for reseating the modules.
  • Ensure your laptop's BIOS/UEFI is updated to the latest version, as older versions might not fully support new memory modules.
  • Test each module individually if you installed multiple, to identify a potentially faulty module.
• System Instability or Blue Screens:
  • This could indicate a faulty module or incompatibility. Run a memory diagnostic tool (e.g., Windows Memory Diagnostic, MemTest86).
  • Verify that the memory specifications (DDR type, speed, voltage) are compatible with your laptop model.

If problems persist, contact Crucial technical support or your laptop manufacturer.
