i have a question about cpu speeds when using throttle stop

[shtaklef]

my laptop is an alienware 17 r5. the specs are NVIDIA GeForce GTX 1080 with 8gb dedicated ram, 32gb ram, 8th Generation Intel Core i9-8 950HK (6-Core, 12MB Cache, up to 4.8GHz w/ Turbo Boost) processor and windows 10 build 1809

i was playing a high end demanding game without throttle stop and i monitored the cpu speed and temperatures by using msi afterburner. i noticed that the cpu speed was often on 4300mhz and that the temperature was in high 80 degrees celcius and it sometimes reached high 90s. there are some games that really push the computer and cause high temperatures

after that i set the maximum processor state to 99% in the advanced power settings and then i ran the game. the cpu speed was fixed at 2900mhz and the temperature dropped a lot and it was between 60 degrees celcius and 70 degrees celcius. that's good but the problem is that i lost my cpu turbo boost

after that i started experimenting with the speed shift epp setting in throttle stop. i know that 0 means push the cpu to the maximum and 255 means to use the cpu very little

the default value of speed shift epp is 128. i ran the game at that value and i saw that the cpu speed was fluctuating but it was mostly on 2900mhz and the temperature was between 60 degrees celcius and 70 degrees celcius. i then set the speed shift epp to 100 and i ran the game. again the cpu speed was fluctuating and it was mostly on 3400mhz or 3700mhz and the temperature was between 70 degrees celcius and 80 degrees celcius. i then set the speed shift epp to 50 and i ran the game. again the cpu speed was fluctuating and it was mostly on 4300mhz and the temperature was above 80 degrees celcius

this is what i don't get. the game performance was the same when the cpu speed was 2900mhz, 3400mhz, 3700mhz or 4300mhz. if i ran the game without throttle stop then the game was free to do what it wanted and it kept on pushing the cpu and the cpu speed was at 4300mhz but the game doesn't need 4300mhz to work. i like to set the value of the speed shift epp to 100 but i am not sure of the consequences. i know that the speed shift epp setting controls the cpu speed in game but what will happen if i reach a part in the game and it needs high cpu speed ? will the speed shift epp value of 100 allow the game to run on high cpu speed or it will force it to use low cpu speed? if high cpu speed is needed and the game was forced to run on low cpu speed then the game performance will be bad

can someone who has used the speed shift epp setting in throttle stop tell me what happened with you and what is the value that you used?

There are some some things that is Intel boost Technolygy that push cpu up to what it can do.
but dont forget own use Powerconsumption that is the battry icon in controll panel. please check if you run in Balances mode, most hardcore gamers know this 3D games require full performance
some laptop has diffrent name like Entertainment Mode or something like that.
i dont think i have seen a app that controll Throttle in this, but it sounds like you have such option with a app.

i only wrote this if you did not know, you might already have full performance, but i still dont like you have temparature so high, but again i dont know that laptop, even i use app that use all 8cpu at core to cure cancer project , maybe test that its a bonic manger with WCG project see config to get all run at maximum and see if this is a heat issue or other bottleneck same time, and ofc. you have use the app that automatic update all BIOS and drivers most new pc today have such app.

and you might want give full Brand /model so we dont look at wrong laptop with diffrent laptop with almost same , bah i forgot you did mention this alienware 17 r5

then i google it, another user seem to have solve some of it, i dont say that is your problem
but it might have.

so do check Dell update site, as i understand it, might be the right support place, only you know that. ( some older model has split support and Dell is not support. )

The modes only tell what happens all the time.
You do not want it running at full performance all the time.

Balanced does it when needed.

my power plan is on balanced

setting the speedshift epp to 100 makes the cpu favor lower speeds but it still allowed the cpu speed to go up at times and then it went back down

if i set it to more than 128 then that will stop the cpu speed from going up and the higher the value the more it stops it

I have exactly the same issue and i dont get it too, what did u do at the final dude?

just pick any value between 100 and 128 and check the cpu temps. as i said less than 128 will allow the cpu to run fast

anyway i am using another solution which is not throttlestop. if you are playing a game which is generating high cpu temp then go to edit power plan, advanced settings, scroll down and find processor state, select maximum processor state on plugged in and change the value from 100% to 99%. that will disable the cpu turbo boost and force the game to run on 2.8ghz and the cpu temps will be quite low. when you finish from the game then set the value back to 100%

some games give high cpu temps when they use the full cpu turbo boost so that's why disabling the cpu turbo boost will lower the cpu temps. if you have a powerful pc then you won't notice any performance drops in the game when you disable the cpu turbo boost

if you want to use the cpu turbo boost but you dont want to use it all then you have to use throttlestop
