I have a MSI B450M Bazooka Motherboard and 4 sticks of GSKILL F4-3000C15D-32GVR RAM, each with a capacity of 16GB. The third and fourth sticks of RAM were installed after the system was initially set up.

The BIOS is version 7A38vH3 and the operating system is Windows 10 Home (64 bit).

Although Windows recognizes the full 64 GB of RAM, it only displays 32 GB as usable.

Any ideas? Thank you!
