    Exclamation Dark Hero 5950x single core performance wall

    I already spent 3 weeks tuning curve optimizer
    search for other people performance and settings


    it does not mater how much i try my maximum cpuz single is 665 with Fmax disable
    it does not boost beyond 5000mhz

    if i enable Fmax it is unstable

    i do have my memory tunned on zen timmings and all the power settings to the optimal settings

    i get the same results setting the overclock to Auto or Curve optimizer to negative 10-6-15-20-20-6-6-7-20-10-20-15-20-20-20-20
    i tunned my cores using clock cycler to make sure that i am on my optimal curve stable

    i saw many other people getting 680 685 on cpu z on single thread


    If anyone have tips how to increase my single thread performance it will be much appreciated

    My setup
    ryzen 9 5950x
    asus dark hero bios 3501 agesa 1.2.0.2
    nvidia rtx 3090
    4x 8gb G.skill 3800 cl14

    Hello,
    A number of items can have an impact on the single threaded performance depending on the workload.

    BIOS and AGESA revision
    Memory latency
    Silicon quality
    Fabric Clock
    BIOS CPU configuration
    You can try disabling FMAX Enhancer and Performance Optimiser. Set PBO to enabled and Max CPU Boost Clock to 200MHz

    Bios is 3501
    agesa 1.2.0.2
    Fabric clock 1900
    memory clock 3800
    1 to 1

    i am getting 55ns on Aida64
    pretty confident that my memory is optimized

    the funny fact that last night i flashback the bios to 2601 and at default setting i get 5050mhz easy

    i will try the bios settings that you suggest and i post the results

    UEFI 2601 contains AGESA 1.1.0.0 Patch C. Boost behaviour between AGESA builds may vary.

    we have the same setup
    ryzen 9 5950x
    asus dark hero bios 3501 agesa 1.2.0.2
    rtx 3090
    4x 8gb G.skill 3800 cl14
    i havent fully tweak this yet, only thing i did now is docp then pbo2
    ppt=200
    tdc =100
    edc = 100
    no boost clock yet 0mhz
    then i se fclk to 1900
    then tune my curve 4 best core negative 20 and the rest on negative 30
    cpuz is at 691 to 698
    still new to amd so im reading on other tweaks to optimise

    that sounds promising

    what is your digi+ settings for the cpu?
    like load line calibration etc

    this settings got me way better on cpuz ... 692 - 695

    i am refining the curve using corecycler 0.8.0.0 to find the curve

    the stronger cores require less negative curve

    as i am tunning thoses it seems to get better score and better stability
    i am using llc auto cpu auto on the digi+
