Netgate SG5100 default bios settings

[vicking]

Hi all,

In my home setup I use a Netgate SG5100 which I did a clean install on after upgrading the hardware, I also resetted the bios settings to default.

One thing I noticed is that intel speedstep was disabled by default, the same for cpu C state which results in a processor (atom C3558) which runs @ 2.2ghz all the time.

I don’t think that is very energy efficient in my home environment and was wondering why these settings are disabled? And can I enable it without a performance hit to reduce some energy usage? Thanks!

Yes, you can enable it. Also enable powerd in pfSense to take advantage of it. I run that here and haven't seen any significant performance issues:
