    so what is the best uCode for me to use (and that I am able to revert back to) if on i7 7700HQ and I want max performance and don't care about the security improvements?

    Check for sep/oct 2019 BIOS release. Microcode version are hard to track and remember.

    + Dell hide what security patches they have added into bios. Avoid bios versions from Dec Oct and forward.

    Yeah, I am on BIOS 1.6.1 and have no intentions to flash up or down anytime soon. I just saw mentions of the mc_update files that apply microcode revisions at boot and wasnt sure if there was performance I could gain back by manipulating a system file or such. If it involves a BIOS flash of any kind I am good. I have lost all trust and faith in Dell's BIOS "updates". Nothing but horror stories all around as far as I can see.

    Be sure you know what you click on. Both from Dell and Win Update. Something nasty can pop up next time you boot up your machine. Not nice... And Dell treat all their models equal. 17 R5, BIOS 1.11.0, no undervolting
    Edit.
    It looks like it's risky with bios updates also before Dec 2019...

    May 2019 BIOS looks good. You can read changelogs and see if they really updated mcu and MEI FW. If its only MEI FW you can grab correct FW from win-raid.

    Intel CPU interconnects can be exploited by malware to leak encryption keys and other info, academic study finds The register.com

    Lord of the Ring (s): The New Vulnerability Discovered in Intl processors elchapuzasinformatico.com

    [​IMG]

    Today we ran into the Lord of the Ring (s) (LOTR) vulnerability in Intel processors , a nod to the Lord of the Rings movie, and this nod is due to a vulnerability linked to the interconnection rings of the processors of the blue company, although in this specific case, it is not critical due to the difficulties that attackers would have to face to access the information.
