Unlock advanced bios version GKCN54WW - Lenovo Legion 5 Pro 16ACH6H 82JQCTO1WW

Hello everyone,

I have a lenovo Legion 5 Pro-16ACH6H 82JQCTO1WW with Ryzen 7 5800h and RTX 3070.

I have a problem with the dram, it run at 1600mhz instead of 3200mhz.

Can you help me for that or give me another solution, pleaaase ? Thanks you a lot for your help
