Memory
Your computer supports a maximum of 16 or 32 GB of memory; however, 32-bit operating systems, can only use a maximum of 4GB of address space. Moreover, certain components within the computer require address space in the 4GB range. Any address space reserved for these components cannot be used by computer memory; therefore, the amount of memory available to a 32-bit operating system is less than 4GB.
- Greater than 4GB memory requires a 64-bit operating system
- Only memory type supported: DDR4 SDRAM
- Not backward compatible with DDR3 memory modules
