Threadripper Pro - Debian netinstall w/ i3 window manager and disabling multithreading

Hi Everyone. I finished my TRPro build (see the photo).

I have the 16 core variant and because I am using this as a primary day trading/investment workstation, will disabling multithreading allow me to run at higher clock speeds during the time I am using it. I don’t believe it would make much difference but wondering if you have any experience in this.

Also, I want to setup a Debian netinstall w/ i3 but any major packages that you would recommend to install specifically for TRPro? Power management etc.

Stupid question, how do I “secure erase” the optane drive? Does it need to be secure erased like nand flash? Have the P5800x

Thanks.
