Additional Notes

  • The dual channel configuration requires two matched modules to double the available memory bandwidth and optimize integrated graphics performance.
  • Use of standard 1.5V DDR3 modules will result in a failure to boot because the motherboard chipset only supports the 1.35V low voltage requirement.
  • Accessing the SO-DIMM slots on the HP Probook 645 G2 necessitates removing the bottom service panel which may involve specialized security screws depending on the regional subclass.
  • Installing a single 16 GB module will result in a non-functional state as the 16 GB maximum capacity is restricted to a 8 GB per slot density limit.
  • Mixing modules with different latency ratings will force the system to default to the slowest timing profile available across both slots.
  • The physical architecture of the internal chassis limits memory height to standard SO-DIMM profiles prohibiting the use of modules with integrated heat spreaders.
  • Upgrading beyond the factory default capacity does not void the hardware warranty provided no physical damage occurs to the internal plastic clips during the installation process.
