Thanks, Mike & Jan.
I’m running on bare metal HP Gen9 blade. I have started looking at the BIOS settings and as far as I can tell there are a lot of options that affect CPU frequency and they are turned on. I will check tomorrow if ‘Spread Spectrum’ is available and is turned on as I don’t have access to the machine right now. I do know that settings like Intel Turbo Boost, and dynamic power control are on. Although HP support says that they are not aware of any settings that impact NTP on the host.

Check your BIOS settings . Sean: plug "bios spread spectrum" into your favourite search engine for more info. You want to disable that for accurate timekeeping. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
