How much RAM does Linux support?
Linux and Unix-based computers Most 32-bit Linux systems only support 4 GB of RAM, unless the PAE kernel is enabled, which allows a 64 GB max. However, 64-bit variants support between 1 and 256 TB. Look for the Maximum Capacity section to see the limit on RAM.
What are the system requirements for Redhat Linux?
