[Tool] Lenovo (H2O) Bios Unlocker and Locker

hey guys. maybe im in the wrong thread but i would like to start somewhere and find solution.
i have a Legion 5 15ACH6H (82JU013FHV) configuration:
https://psref.lenovo.com/Detail/Legion/Legion_5_15ACH6H?M=82ju013fhv

the actual BIOS/UEFI version is GKCN65WW.

and i replaced the RAM modules with two Patriot Memory Viper Steel PVS416G320C8S modules:

not sure is the hardware or the firmware able to handle XMP but if possible i would like to unlock it somehow or at least change the memory timings to get the best performance out of it. some deeper fan control options would be good to. so is this tool capable for these things or i’m in the wrong place? or if any other tools can unlock hidden options please navigate me. thanks.

The system doesn’t support XMP, and changing any of the RAM related settings in the bios will result in a brick. The best you can do is get a paid version of Thaiphoon Burner, and check if you are able to edit the RAM timings there. There is a chance your ram sticks are locked however.

oh damn. thanks for the info. btw how should we know if it support XMP on hardware level? how people know before/after buy? does AIDA or HWiNFO, etc can tell anything?

if i cannot change timing what else can do with this tool on my machine?

If you can’t change timings with Thaiphoon, the best you can do is get the CL20 kit from HyperX

no chance, I have the exactly same laptop model as you do and changing the memory timing resulted in a brick. Although I could restore my laptop by disconnecting battery, cmos battery and swapping ram sticks.

Anyone have any luck with the Ideapad 5 Pro 16ACH6 with the gtx 1650?
