FYI: Some bioses will reset the cpu frequency to a lower value if the
machine is reset during a post. (Thinking the user overclocked the cpu,
which caused the system to not boot)

Hi, All.
Why does my 4.8-PRERELEASE detect my CPU as 1000 MHz instead of real
1200 MHz ?
Just because the processor is rated at 1200 doesn't mean that the
motherboard is running it at that speed.
Any time I've seen this problem, it was because the motherboard was
left to autodetect the CPU speed and didn't do so correctly (don't
know why they seem to incorrectly guess 1G) Check your BIOS settings.

I have some FreeBSD-boxes running with CPU frequency lower than 1GHz -
FreeBSD detects them correctly.
Is it some kind of misconfiguration ? Can it cause problems ?
Thanks a lot.
WBR.
