Identifies the configured speed of the memory device, in megatransfers per second (MT/s)

The ‘extended_speed’ and ‘extended_configured_memory_speed’ fields are intended to represent memory devices that operate faster than 65,535 MT/s, which cannot be described using the Speed or Configured Memory Speed fields. These fields are only meaningful if the value in the Speed or Configured Memory Speed fields are FFFFh. For compatibility with older SMBIOS parsers, memory devices slower than 65,535 MT/s should represent their speed using the Speed and Configured Memory Speed fields, leaving the Extended Speed and Extended Configured Memory Speed fields set to 0.

Bit 31 is reserved for future use and must be set to 0 Bits 30:0 represent the speed or configured memory speed of the device in MT/s.
