8750h - intel XTU

[vladNMP]

hi, down you have a graph of intel XTU. i just have gta5 loading screen and main menu (did not get in game) and playing with it's settings and downloading something with 2mb/s in the background. i am a bit worried about the throttle. my xtu settings are: uv: -125mv, Power short max and power max: 65w i am worried about this setting, (the power limit throttling goes to max)

why worry? It's totally normal for all mobile devices

the 65w values seem odd... i think i might.ve screwed them up some time ago and intel xtu does not have a reset thingy

Default power limit is 45w for long and 78w for short, but OEMs can totally ship devices with different settings.

so let's say i do modify them to the 45/78. what would be my target for a better experience? lowering which one? increasing which?

no, lowering power limit = lower speed.

First, what you're experiencing is the auto-protect feature built into your CPU.  If you were using Throttle Stop it would be a little easier to see what I'm referring to, but there is a way to increase the length of full power draw, or in your case the desired 78w to an indefinite duration.  However, this is risky and completely unnecessary.  I saw you running a 125mv undervolt which is pretty good considering.  I'd say stop tinkering with stuff before you're looking for a burn recovery drive.  Celebrate your win and enjoy your tech!

Most guides online that refer to modding bios or system registries are specific to that machine, and even more specifically, to the hardware inside their particular machine.

If you want an easy boost to your machine I saw you had no issues with thermals.  You can boost your core clock multipliers for extra power under load during the time it's drawing full power.  Just be sure to adjust according to your system's cooling ability.  Too high of a multiplier will result in premature throttling.  Too low of a multiplier will leave you with a slow machine.

okay, playing with undervolting caused my windows to crash, and i got these defaults: Turbo boost: 45W, Turbo Short: 90W. which should i increase bit by bit to improve stability and performance?

actually i've been playing with the undervolting and got my system stable at -160mV (15 mins of stressing, 1h of GTAV, gta sometimes ran under my refresh rate, 120, which means my machine can't keep up which means it was at full power). undervolting the GPU seems a bit complicated, can't keep up with the tutorials, out of my league (using msi afterburner, current system: msi ge73 8750h/1070)

Turbo boost (PL1). I dont like raising turbo short (PL2) because it leads to overheating during that seconds of burst in clock speed and voltage.

Mobile GPUs dont let you tune power limit, the easier way is to just overclock. Your GPU will hit the power limit earlier and use a lower voltage point instead, since you overclocked it might still run faster, effectively undervolting at the same time
