NOTE: This chart does not represent all possible memory configurations. Due to the non-industry

 

standard nature of some third-party memory modules, we strongly recommend using only HP branded

 

memory modules to ensure compatibility. If you mix memory speeds, the system will perform at the lower

 

memory speed.
