HP ZBook 17 G3 - Memory Issue

HP Recommended
Microsoft Windows 10 (64-bit)

So I have just upgraded my memory to 32gb, I have made sure to purchase the exact same spec of RAM - In the laptop the existing memory was Samsung DDR4 2400 speed memory - the additional 2 sticks is Samsung, same speed and timings. 


My laptop memory shows running as 2133 speed. 


I see no options in bios to change - what could the issue be?

The specs says

  • Four SODIMM slots supporting dual-channel memory
  • 4 GB, 8GB and 16 GB SODIMMs (for Intel® Core™ Processors)
  • 8GB and 16 GB ECC SODIMMs (for Intel® XEON® Processors)

RAM can be 2400MHz or 2666MHz but they only run at 2133MHz
