Intel's Thermal Velocity Boost isn't what it's supposed to be...

    It's completely different on laptops than on desktops.
    And a MSR controls it on desktops, and you can even change it in RW Everything.

    It actually works (designed to work with adaptive voltage to change the VID) from being based on 100C for stable CPU voltage to lowering it based on temps. Not frequency. VID.

    On laptops it's TERMINAL VELOCITY BOOST.

    See... “NO site actually talked about and examined the latest feature of the i9, Thermal Velocity Boost TVB“ Why should they?

    you know back in the old days, companies came up with these new features seem to be great and all and that actually benefits the consumer. overtime with too much dominance it becomes the opposite, new features are to mask up the poor and inferior quality of a product, to make consumers spend more while giving less.

    intel's turbo boost 1/2, speedshift were good example of improvements, optimization of their hardware. battery boost NOS, nvidia's MAX-Q, intel's TDP change and TVB are examples of later.

    I noticed CPU voltage dependency on it's temperature long time ago, going back to original core2duo I think. When undervolted, my CPU was stable till 70-80C, if it got hotter than that it would BSOD. Without undervolting, it would be stable all the way to 100C, but it would run hotter to begin with, so it was balancing act between cooling and undervolting.
    So how difficult would it be to program ThrottleStop to dynamically adjust undervolt based on CPU temperature?
    BTW Intel must be hitting some "walls" to come up with this. Probably has problem dissipating so much heat from such small cpu area.

    Amazing finding:) just to let everyone know... it is only supported on 8th Generation CPU Processors and upwards..:(

    Which is sad news to me... I got a 6th gen. So.. I will miss the adventure of bricking my laptop while tinkering with this feature:D:oops:

    Don't despair, you can always brick it by making it wisper quiet by disconnecting the fans or repaste cpu with plenty of liquid metal.

    Aha! I wondered what was behind my stable undervolt shifting up and down over a range about 50mV. Sometimes stable at -110mV, other times not below -60mV... perhaps this is it.

    Start a bench from cold, the cpu is undervolting itself on top of user settings, it's too much

    Is TVB automatically disabled when using static voltage?

    On desktops, I don't know because TVB affects the *VID*, but I've already done multiple tests and static voltage completely overrides the VID, making TVB irrelevant. On laptops, probably not.
    You guys should check the MSR's mentioned in the first post (if it's even available on a Clevo with a 9900K) and see what happens.
