#1 [REQUEST] Unlock BIOS for Lenovo Legion 7 (2021 model) by dt_pro 21.06.2021 08:53

Hello,

I have a Lenovo Legion 7 (16ACHG6) with a Ryzen 5900HX and an RTX3080 (Model 82N6000USB), and the bios is really limited. I would like to get the bios unlocked so I can set the memory timings, tweak the CPU voltage, and so on, pretty much all the bells and whistles. I have the latest bios version GKCN36WW. Please Help! Thanks in advance!

PS: I have CH341A programmer + SOIC8 clip

D.

Lol, you love Lenovo laptops

Didn't you own the Previous model of the Legion?

Just moved from an Intel-based Legion (which throttled like crazy and has a swollen battery) to this AMD one and it doesn't seem to like the RAM upgrade. In Windows and the BIOS, It freezes and refuses to boot until fully power-cycled, freezes in Windows memory testing and shuts down in memtest86 (without any errors beforehand). I also BSOD'd on an unexpected kernel mode trap, highly likely it's the RAM causing issues.

Based on my recent 30+ hour RAM OC stretch on an X570 desktop (tuned 3733C14!) I know this is due to RAM voltage being too low (alternatively, raising the VDDG/CLDO VDDP and VDDSOC voltages could help but I'm not sure that's preferable).

Happy to contribute some funds (say $25) if someone creates a BIOS (or says he'll create one) before I return this thing.

Is there any update on this at all, interested in the development as I have the Legion 5 model.
