    Can I use this guide to tune 10870h?

    Sure, the same basic concepts apply to almost any Intel CPU in fact.

    So if I set Uncore to +125mV offset in BIOS, I can't use Intel XTU for overclocking then, right? Because whenever you set a Core Voltage offset, it copies that to Cache Voltage, which is also the Uncore voltage? Overriding the value you entered in BIOS...

    I have similar Samsung RAM (same model number but different three letters after hyphen) and I can't seem to get it to boot past 2933MHz (133x11). Tried raising voltage, loosening timings, increasing Uncore, etc.

    Hi @hackness , does the above still work for the i7-11800H (MSI GE/GP76 laptop)?

    Here is a picture of my advanced BIOS, with the default values boxed in green. I have changed only the IMON parts and that works perfect to prevent all PL related throttles. But because the default TDC and VR current values are different from the values you gave (which is more than 2 years ago for a different laptop), I was hesitant to change them. Any advice regarding the appropriate values for this CPU?

    I should also mention that Dragon Center is no more, now replaced with MSI Center, though that probably doesn't affect what we can adjust in the BIOS settings.

    IMON - power limit "bypass"
    VR - EDP limit "iccmax" - 420VR-105A top usage
    TDC - heat signal + VR - 61A

    ,,,info above
    AC /DC loadline "1" - works best "but need set custom voltage .,,this removals all over-voltage boost - get static voltage + 0.045mV kick in load
    for speedshift / adaptive scale -- must add OFFSET for repair "around 50-65mV"

    full vcore calculation"AC/DC 0.01"
    vcore / offset + 0.045 - top end voltage

    /// or use only power bypass -- IMON

    best HWINFO + read sensor

    CPU LIMIT REASON -- here verify problems

    edit
    and for this notebook 11800H impossible remove all limits ! heat is problem
    recommended check ParkControl or similar app for better results

    you try overdrive PL1,.2 ,in bios ? this not works ??
    CPU power/performance domain .,,.this notebook need working PL limits o_O


    good luck

    Sorry I have a very hard time understanding you (as an example, I have no clue what "TDC - heat signal" is supposed to mean; it has only Enable and Disable options), but thanks for the effort!

    any stress + reading in HWINFO "cpu limit reason"
    ,after this verification ? .,,remove problem

    or use only defaults setup ,.,if you don't know what it is :D

    TDC - turned off to avoid further limits "VR heat / long stress stability"
    but is possitible VR defect or shutdown

    TDC - thermal design current "1/8 setup - amperes " // VR current- iccmax top current "EDP limit -1/4 setup - amperes"

    Finally figured out how to make my GS73 6RF to enter package c-state higher than c3. Enable every ASPM related settings in the unlocked BIOS allow mine to enter package c8.

    I had bricked my factory BIOS playing around and flashed with a slightly newer version (actually from a different reseller but provided by Clevo so...)

    New BIOS working great and laptop running smooth other than 1 change. I had previously achieved -190 mV undervolt with rock solid stability and a load voltage of ~0.945 V @ 3.9GHz. This was repeatable for hours and hours and hours.

    Well new BIOS I was able to only get about -0.165mV undervolt before errors and lots of instability. The chip ran closer to ~0.965mV @ 3.9GHz and I felt a good ~5C hotter than my previous BIOS.

    Miffed, I got to digging and reading. The knowledgeable will know right off the bat to check things like IA Core AC/DC Loadline and compare to my previous BIOS but it took me a lot of time to find that solution.

    As it turns out my previous value was "180" and my new BIOS had it set to....130.

    I am now back to running 180 and have a very cool running 8750H again!
