## 2.4 Memory 

The maximum physical memory size is directly related to the number of CPC drawers in the system. Each CPC drawer can contain up to 8000 GB of physical memory, for a total of 8000 GB + (3 x 8192 GB) = 32576 GB, which is approximately 32 TB of installed (physical) memory per system. 

The maximum and minimum memory sizes that you can order for each z14 model are listed in Table 2-3.

The minimum physical installed memory is 512 GB per CPC drawer. The minimum initial amount of memory that can be ordered is 256 GB for all z14 models. The maximum customer memory size is based on the physical installed memory minus the RAIM and minus the hardware system area (HSA) memory, which has a fixed amount of 192 GB. 

The memory granularity, which is based on the installed customer memory, is listed in Table 2-4.
