Additional Notes

  • The HP Elitebook 840 G1 motherboard requires low voltage 1.35V modules to ensure system stability and prevent boot failures associated with standard 1.5V memory.
  • The Presence of 2 physical slots facilitates dual channel memory architecture which doubles the available bandwidth for integrated graphics processing.
  • The 16 GB capacity limit restricts virtual machine density and heavy multitasking in 64 bit operating environments.
  • Installation of memory modules requires a non destructive removal of the bottom chassis cover which typically allows for maintenance without voiding hardware service agreements.
  • Internal memory controller limitations prevent the hardware from utilizing frequency overhead if modules faster than 1600 MHz are installed.
  • Dual slot configuration necessitates the removal of existing modules to reach the maximum supported capacity if both slots are currently occupied by low capacity sticks.
  • Latency performance is governed by the slowest installed module because the system synchronizes both channels to the highest common denominator.
