HP M8400f RAM Capacity

RAM speed depends on the motherboard's front side bus speed.

The HP Pavilion Media Center m8400f is a desktop computer that was released by Hewlett-Packard/Compaq in 2007. The installed operating system for this model was Windows Vista Home Premium.

Standard RAM

The HP Pavilion Media Center m8400f came equipped with 3 MB of PC2-6400 DDR2 RAM. This model has four slots for RAM. Two 512 MB modules and two 1 GB modules were originally installed.

Maximum Capacity

The maximum RAM that can be installed in the HP Pavilion Media Center m8400f is 8 GB--four 2 GB modules of DDR2 800 240-pin PC2-6400 RAM. The RAM should be non-ECC. It is possible to install pairs of modules that do not match, but it is not recommended due to the system's support of dual-channel memory.

Operating System Limitations

If the computer is running a 64-bit operating system, the operating system will recognize the entire 8 GB of RAM. If it is running a 32-bit operating system, only 3.5 to 4 GB will be usable. Therefore, there is no reason to install more than 4 GB of RAM with a 32-bit operating system.
