Hello

My system is blade 15 12800h 3070ti.

I’m unlucky to buy 2022 model. Cause 2020, 2021 (after bios editing) and 2023 allows undervolting, but 2022 - don’t.

There are overclocking lock & undervolt protection. Cpu runs 2400-2800Mhz 1.1v, heats to 100°C and use all of TGP. Laptop is useless without voltages customisation, even after repaste and with cooling-pad.

For example, my desktop cpu 12900k needs 1,1v to run 5200 all cores.

I implore you, can you please make a BIOS that unlocks undervolting? This is strictly important to me. Don’t want to buy another vendor’s laptop. I agree to refuse my warranty. I don’t need it.

I will respect you. And a lot of other 2022-model users too.

12900h processors can’t be undervolted, only the HX variants can.  I think you might have a cooling issue.


You would never get 5.2 sustained anyway, even with an undervolt. I have the 2022 blade 15 oled and mine sustains 4.5gz no undervolt, using about 35-40 watts.  For comparison my old 2020 with 10850h could only sustain 3.8ghz with the same power, so this is quite good.


The chasis can only really handle about 100 - 120 watts of sustained power between cpu/gpu anyway.  That leaves 80w for the gpu and a little headroom for boost.


After repaisting my 2022 wth 12900H with PTM7950. I find the laptop truely silent on silent mode and stays at around 90c/85c cpu/gpu under heavy gaming.  Fans are not obnoxious either. 


I think this is close to the best you can hope to achive with a thin and light design and it’s quite good imo.
