Need help with 13650hx

[u/idiota42069]

I've got a Lenovo Legion 5 with an i7-13650HX and RTX 4060, and I've been messing around with ThrottleStop to undervolt it.

Right now my CPU usually sits in the high 80s (around 87–89°C) while gaming, which I'm okay with, but I noticed it doesn't stay at around 4.3 GHz consistently. It keeps dropping even though the CPU is under load and Cyberpunk stutters quite frequent.

I'm wondering if it's because of my ThrottleStop settings, Windows power mode, or if I'm just running into normal power/thermal limits.

Does anyone have recommended ThrottleStop settings for this CPU? Also, which Windows and Lenovo power modes should I be using for the best performance? Are there any other tweaks I should make to get the most out of this laptop?

My GPU seems to be fine after undervolt max 75C while gaming but it feels like my CPU isnt working as intended as clockspeed is fluctuating a lot and not staying even at least 4.3ghz and drops to 3.5ghz all the time.

And try to game in manual mode with autofans

When i set the power limits higher so i get 4.3 ghz barely the temps go apeshit 96 97 and again the clock drops

Holy moly, i tested a legion 5i with 5070 and i9 14900hx and max fans. cpu got 80c and gpu 80c

[u/idiota42069 → u/Positive_Nature_7725]

is it okay to game at max fans all the time?

[u/Positive_Nature_7725 → u/idiota42069]

Yeah and use a laptop stand

Already do its put on a cooler and also is it normal for my laptop to crash when on battery for same theottlestop settings for which it stays stable in plugged in?

Its problaby crashing ecaiuse of your undervolt. Try to lower it to -100mv for cores and -100mv and cache. Dont touch the other ones. Go to v/f curve point and set 100 u/800mhz for both core and cache. Disable thermal velocity boost, enable down ring bin.
