    As I said many time here those vulnerables need both hardware and software especially OS Optimized together to
    mitigation in better shape. Compared to cars engine used emergency mode on ECU to avoid many parts failure thus *
    these mode consume more petrols than default. But it save the engine and part lifespan not shorten lifespan.

    Idle temp increase around 5-6 degree Celsius was not seriously situation for CPU itself at all . In terms of these
    for me did not disappoint solutions at all.

    2. Following 0200004D there are 02000050 and now 02000055 which I used for testing with W10 2019 18298.1000.
    There are many area that improve over 0200004D especially AVX2/FMA3 heavy loaded and AVX512/FMA3 loaded
    CPU was more efficiently to run full 100% load under 55 degrees Celsius. (Lower than pre mitigation microcode a lot ).

    3. Idle state increased around 5-6 degree and full load below 55 degree Celsius didn’t harmful or shorten your CPU life at all.

    From 1-3 l’d like to say intel trying to do their best solution for vulnerable mitigation. Hope you all don’t be panic on Idle temp *increased*
    and enjoy your CPU performance. Cheerful.*

    I agree with some of what you typed, but 5c - 6c increase at idle is a lot. I have around a 19c idle, and it magically increases to 24c-25c with
    those microcodes, that's a 30% increase in temperature at idle and 7%-10% at load. Some people have reported no difference in
    temperatures, and it's doesn't seem to use any more watts at idle. So if the cpu is working harder at idle, why isn't it using more watts
    at idle? That's why I think it could be a reporting issue, but I'm no expert and could be wrong. (I've been wrong before... haha)


    btw.... I know sometimes things can be read/taken differently on the forums, but my message is a friendly conversation and not a
    flaming rant against you. I appreciate all the information you provide, and all the work you did on the BIOS'es.

    Below 55 degree Celsius in full load (overclock)?! How? With liquid nitrogen?! I hope they solve this problem as soon as possible...

    Full load mean utilized both 512-bit FMA unit on Skylake X SKU, TJ Max default was 105 degree Celsius, Full loaded below 55 degree Celsius was 50 degree Celsius below TJ Max . My system used only Kraken X62 AIO see more info on BIOS 1503 quote.

    it is because of the microcode 4D of 1603
    With the same bios and microcode 43 or 49, no problem (TJMax at 105° and good temperatures) as with the old bios

    According to Intel, the microcode should not increase the TJMax, and they will do tests, finally I hope
    And if it will be related to one function or another, the consumption of the CPU will be increased with the increase of the temperature
    Except that the CPU consumption is the same, just the temperature increases

    I had a response from the technical department of Intel, and so Intel has voluntarily increased the TJMax of Skylake-X since the microcode 4D (I wait they give me the reason, if there is one) and therefore this increase of the temps of the cores is normal since the distance of the TJMax has changed

    By cons, there is a bug, when we put the TJMax 105C in the bios, it is 105C under Windows, but the temps of the cores is always increased
    A bug on the Intel or Asus side....

    The question is have temps increase or are they only reading as higher when there indeed normal,

    The distance of the TJmax remains the same, but the cores temps are increased, example

    TJMax 105° : load at 70° => distance from TJmax 35°
    TJMax 110° : load at 75° distance from TJmax 35°

    simple calculation to do

    Actual TJUNCTION for 7980xe is 94°C according to Intel
    *https://www.intel.com/content/www/us...i9-7980xe.html
    **1603 shows higher readings , 1503 doesn’t, with same OS(win 10), I would think it’s a bios issue and not OS

    Of course is not an OS issue, it's bios or/and new microcode

    And the temperature of the CPU package is also increased (from memory)
