Have you improved it?

Post W11 24H2 update and adjusting CPU Core to -148 and E-cache -100

Cinebench R23: 33241

GPU overclock
Core Freq. offset: +250Mhz

UV should be enough, I would leave the core ratios as they were if you're after maximum performance.

#

P-Core ratio adjustment to 52 with minor bumps in score. Will eventually dive into Afterburner for tweaks but content for a newbie.

Nice one 🙂

astral urchin Nice one 🙂

Thanks! I’m in awe with your 🔥benches, mate!

Increase core freq. offset: +250Mhz to +275Mhz
and memory freq. offset: +750 to +775

Nice bump in score including graphics and CPU. CPU temps peaked 81C, 1.339v, no limit reasons.

are you using a cooler on your laptop to reach 30k+ on cinebench? i have the same cpu and max i could get is 28k+ it's also undervolted but peaking around 96-97, my laptop is the legion 5 pro though so your 7 pro might have better cooling, im just at a lost

5 pro doesn’t have vapour chamber and LM on cpu like 7 pro have. I can achieve 85c and 37K in cinebench with max fans and no external fans, with pad 70/75c max

high tide Jan 20, 2025, 2:50 PM

#

i see, thanks for the info, is there any way i could achieve lower temps on the 5 pro?

#

i've tried undervolting down to -175 but went back to -125 since that one had the best results

Use it raised and not flat, UV doesn’t mean lower temp because new cpu will tend to just boost higher when they have the thermal headroom. Another thing would be clean the fans when you can, live in a dust free environment and use AC when in hot temperature. If you have money, invest in an active cooling pad like llanoV12 ecc

v12's arriving soon, ac is on always, and the laptop was purchased 2 days ago so i'll be good with the cleaning till then

Flat or raised?

high tide Jan 20, 2025, 2:54 PM

#

i've ran it flat on the desk ever since i got it, i have nothing i can use to raise it

Use the box of the mouse or a book, put it under where all the ports on the back are. It will increase the airflow

high tide Jan 20, 2025, 2:56 PM

#

i might need to put it under the center of the laptop
