Hi,

I ordered the following for a home server and I would really appreciate some advice:

Intel Core i7 7800X
Gigabyte X299 AORUS Gaming 3
MSI GeForce GT 1030 Heatsink

It will serve SMB, Plex, Zoneminder & Home Assistant as well as transcoding my Blurays to x265.

It's going to be running 24/7 so I want it to be quiet and the idle power consumption to be low and was thinking I could underclock the CPU and the video card, is this a good idea, also what about disabling HT and Turbo?

For everything but x265 it could probably get away with a lot less grunt and I could set the CPU back to defaults if I was going to do a lot of transcoding.

What is the state of reclocking in Linux?

Thanks for looking.

Richard

Ondemand works great. As stated, I use it on my daily driver and experience no issues with performance while still having a CPU that runs @ 1.6Ghz most of the time to save power.

Definitely the best of both worlds.

I wouldn't underclock your CPU or GPU. Just enable EIST (or whatever it's called) and let the system do the downclocking automatically.
