- | For 32-bit (non-PAE enabled) Linux, the maximum addressable user-space RAM is around 3 GB. | + | The bottom line, as of the year 2016, there is absolutely no benefit for an AstLinux system to have more than 2 GB of RAM, more can exist but is unnecessary. |
- | Currently | + | For 32-bit |
+ | For 64-bit (x86_64) Linux, the maximum addressable RAM is only limited by your hardware, so you would expect to see about 4 GB with 4 GB RAM installed, but with the AstLinux system, the bootloader is RUNNIX (a 32-bit, non-PAE enabled Linux Kernel) which is common across all AstLinux board types. | ||

+ | The AstLinux developers have demonstrated that if the RUNNIX bootloader was compiled with a 32-bit, PAE enabled Linux Kernel, the " | ||

+ | The added confusion of multiple RUNNIX flavors would not actually solve a real-world problem, so the maximum recognized RAM currently remains at 3 GB. The day when greater then 3 GB RAM is useful, the RUNNIX bootloader can be compiled with a PAE enabled Linux Kernel. | ||
