    You are certain you don't have your TDP in bios set to 35W?

    As i said itd called configurable tdp got level 0 and level 1 level 0 is normal running one caller normal where cpu runs at 45W level 1 is called down and sets cput to 35W when gpu runs i set custom limit on everything to 70W and still same issue

    Try lowering iGPU frequency. For i7 8750, dropping by 50 MHz solved EDP other (I think I was 1100 -> 1050 MHz)


    Also please post what you did to solve the PL issue, I would like to try on an Asus TUF FX I have laying around. Thank you!

    I have a TUF FX705GE and I dont have any PL problems, just keep in mind that the latest BIOS disables undervolting, so block it on Windows(Disable the Firmware device in Device Manager) and flash version 305 of the BIOS.

    The FX504 lock down to 35W or 25W if CPU and GPU is on, regardless of temperature. Its horrible, and BIOS is locked right.

    Oh, yeah the FX50x models from what I have read have some atrocious BIOS and EC limits.
    I was able to unlock my BIOS with help from Lost_N_Bios over at win-raid forums, maybe request his help.

    your IMON set not works
    90W real -- 12W prim95 on aida get 5w :D

    IA/core domain
    31999
    negative
    slope 50
    and must disable all LOCK or send bios name/notebook name "i check all in FILE --LOCK" for better correct setup :confused:


    edit
    only need IMON not more

    custom VR -- TDC is enabled defaults
    and total power is 195w /hybrid power ? --PSYS

    The 1050MHz trick gave me constand edp other

    And here is what i did
    Disable TDC VR for cpu/IA core
    Set VR current limit to 928 in bios = 232amps in ts
    Set AC and DC loadline to 1 "make sure you remove your undervolting before doing that first"
    Set cpu core imon slope to 50
    And imon offset to 31999 and dont forget the negative sign
    Go to TDP power limits set PL1 and PL2 to 70Watts everywhere for me i had to levels i set 70W in both.

    Now in throttle stop my cache ratio was 8-39 i changed it to 8-30 no effect on performance but massive heat and power improvment.
    Click TPL in TS and uncheck clamp at the power limits and set long and short to 70W.
    Now go to fivr and at cpu cache increase its icc max current to 232amps like the core.
    These are all the stuff i did and seems like this combination made my life easier.
    Keep in mine these srr on i5 8300H not i7

    EDP OTHER under ring shows when the min on your cache ratio is below the base clock rate of the processor. For your processor it's 2.3Ghz base clock, so setting cache ratio min to 23 will stop that.

    I think that is not a big issue then if EDP other appears i mean it will not cause any frequency drops or anything its just like a warning or a limit popup right?

    How to Go to TDP power limits in bios and set PL1 and PL2 to 70Watts.
    Can u pls explain? Tnx

    I dont remember names exactly since i am not in front of my laptop
    But
    Advanced > power and performance > cpu power > Config TDP configurations
    Set power limit 1 and 2 to 70000

    In my case as you will see there is nominal and down and whatever value i put there it still gets to the 35W limit of down when dgpu starts running but in HWinfo you will see the power limit is actually 70W after set in bios

    Thats exactly our main issues over here
    Set both pl1 and pl2 at two options under 45w and 35w but frankly setting them to 70000 would still make cpu lock at 35W
    Also your maximum limit is 90W so set both pl1 and pl2 to about 85W would be perfect

    It should only pop up when your cpu is in idle, it just means that the cache to cpu ratio has dropped below base clock. It does this for the reason of saving battery, like an efficiency type of thing. You can always go into bios and change the default minimum if it bothers you.

    You will also need to change the time window if you are getting PL1 problem.

    you shouldn't need to change PL1 though. Is PL3 giving problems to?

    If it still gives you power limit problem, there's one more thing to change.

    None shows any problems throttle stop only reports pl2
    And in hw info

    Its ring max voltage, iccmax, pl4 yes
    And IA pl2,pl3 yes
    So its kinda confusing but i think by using the fixes combination i mentioned earlier i no more get that and pl throttle only occurs when running aida64 for stress testing nothing more so i think the pl throttle aida64 causes is the actual chip design limit maybe

    power limits override not works on locked H cpu
    send info BIOS Name 10C ?
    and imon not works - not see any different after this ?

    no need 200amp ++ why :D

    on this notebooks not works PL overdrive only IMON
    tested 9rcx ,,some 8th H cpuS
    only way is IMON -not works ,..,,.,not possible help
    some controls EC - need full battery + AC all time

    remove all app for cpu \\dragon\\TS\XTU all ,,restore bios defaults ,,and set ONLY IMON

    Haha yes i agree... but let them at least try and see for themselves. I've told already why set 200 amp? :confused:... It does nothing. I've told him that PL2 code will show up when both cpu and gpu are underload because the gpu needs power too. :p

    This is only happening for him on a benchmarking program, not normal use. :rolleyes:
    He is hitting no thermal throttle and is able to sustain all cores at 3.9Ghz.
    That's excellent, and i think he is done. So now just be happy and play some video games. :D

    You are very fortunate, not many people have been able to squeeze the max out of their cpu without throttling eventually.

    Now time to run msi afterburner and use its overclock scanner to squeeze the max out of your gpu. I actually find that it lets the gpu run with higher clock rates at lower voltage then stock... o_O the cards in these laptops have to be modulated, just to save energy... like who is actually going to game on laptop battery, 45 mins and it will be dead :rolleyes:

    Thanks to msi their turbo mode in dragon center allows me to overlock the card by 200MHz for core and 250 for memory which msi claims it is within their safe limits

    Dragon center is a joke to me. It messing with the bios settings and makes the performance worst. If you really like to overclock yr gpu, use afterburner instead. For fan curves there is also the "silent option" software. My opinion....

    Dragon Center feels like training wheels on a performance bike.

    Afterburner + Silent Option is more appropriate.
    Btw, when did ThrottleStop stop being the go-to for undervolting? Just found out from screencaps here about QuickCPU. (I know, Intel XTU too, but TS was/is much better)

    so i read the whole thread and i am using pretty much every knowledge there is on this forum, imon slopes etc, got my ge75 8se cinebench r15 scores up to 1260 and r20 to 3075, now i am left wondering is there any way i can go to 4ghz or 4.1 on all cores? any bios mods? i am not thermal limited as i have modded cooling alot and only maxing @75c when running constantly benchmarks, so getting that extra .1-.3 ghz would be nice extra, any help is appreciated

    There is a more advanced BIOS you can get from Svet that allows you to raise the BCLK (maybe FCLK, I forget). You can maybe get that extra 100 mHz.

    Impossible to change the CPU multipliers.
    You can MAYBE create an ICC profile to allow BCKL overclocking, but the maximum is 103Mhz, and not all systems are stable at that, and that gains you 100Mhz at the max multiplier..

    Hello everyone, I just want to say thanks for all the info in this thread. But for the love of god I can't make my I7 9750H run stable with AC/DC Loadline 1, Windows keeps giving me bsod for no reason.. I can't make it stable, and before it was.

    Are you UVed? The other option is to set positive voltage offset.

    I'm not aplying any UV to the cpu, and how about the positive voltage offset??
    I'm using AC / DC Loadline at 50 each, if I go to 1 I get BSOD playing games or even in the desktop during idle.

    With AC/DC loadline at 1 you might need to give the CPU more voltage, TBH doesn't seem to be all that usefull instead of just using the stock values and undervolting.

    I guess my only option is to try stock settings at least on AC/DC Loadline and unvervolt with throttleStop
