These are the BIOS options;
CPU Spread Spectrum [Auto]
Allows you to enable or disable the CPU spread spectrum.
Configuration options: [Auto] [Disabled]
PCIE Spread Spectrum [Auto]
Allows you to enable or disable the PCIE spread spectrum.
Configuration options: [Auto] [Disabled]
They are both set to 'Auto' (default).
Checking these involved a reboot. And now 'frequency' seems to be
returning to it's original value.
