The Effective Memory is the difference between Total Physical Memory and the sum of
all memory reserved for internal usage, RAS redundancy and SMRAM. This difference
includes the sum of all DDR3 DIMMs that failed Memory BIST during POST or were
disabled by the BIOS during the memory discovery phase in order to optimize
memory configuration.
Note: Some server operating systems do not display the total physical memory installed.
