    Help me beat my Manual OC score with Undervolt and PBO!

    To put it simply your cpu is most likely at it's limit

    It has to handle an overclock and an xmp/dcop profile 

    So first the imc just simply is at it's limit and the interconnect cannot handle and overclock and an xmp profile at the same time 

    It's FCLK is really bad and im even surprised you got to this point lmao 

    Lol! For some reason the benchmarks show higher but the game performance is kind of bad (im playing at 4k so it's very noticable in some areas). Maybe I should revert back to 4.1GHz at 1.4V (Manual OC)?

    Hi!

     

    I had some questions and need some answers.
    Please examine all of this and help me figure out what I should do.

     

    CPU: Ryzen 7 2700x
    Motherboard: Gigabyte X470 Aorus Gaming 7
    BIOS version: F4g

     

    Did a manual OC across all cores with: 
    Vcore to 1.4V
    Medium LLC
    And it only helped me reach 4.1GHz.
    4.2Ghz was asking for more than ~1.45-1.5V
    XMP profile for ram set to Profile 1 (3600MHz)
    Cinebench score - 4121 (Highest so far in my tests)
    Nothing failed in prime95 test too

     

    F4g is the version that has a PBO Scalar setting
    It was removed from newer versions of BIOS for some reason

     

    My old temps (no oc) were definitely more than this before I undervolted. They were around ~90c and idled around ~70c

     

    Overvolting helped me a lot? but,
    PBO is not able to push above 3999 or 4000 on load 
    It pushes 4.32GHz on idle on one of the cores for some reason
    Temps are definitely better
    And I beat my previous 4GHz manual OC score in cinebench too

     

    PBO Settings:

    PBO X10
    PPT 1000
    TDC 114
    EDC 168
    vCore Offset -0.1v
    MediumLLC (both) 
    3600MHz XMP Profile 1 on RAM
    Max Temp Reached 84.5C
    Idle Temps ~50-60c
    Cinebench Score - 3929

     

    I've chosen the max values that Ryzen Master showed for (PPT, TDC, EDC)
    I've set all of the values through BIOS.

     

    The Undervolt looks pretty stable but I feel like I could do better and I'm missing a main point here.

    I used 3 softwares CPU-Z, HWiNFO and Open Hardware Monitor and the readings do differ in each of them.

    I've included all the pictures of after OC (load and idle) and cinebench scores
    And the pictures of the BIOS settings I was talking about
    Please take a look at them here:

    I'm new to OC and messing with BIOS but I really like it!

    So can someone please help me understand why it isn't pushing above that 4GHz or 3.9Ghz on PBO?


    How can I improve the performance?

    And most importantly help me beat that manual OC 4.1GHz Cinebench score!

     

    Thank You!
