Successfully enabled XMP and advanced BIOS on Lenovo Legion 7i - 11800h 3070 16ITHg6

I recently got the Legion 7i 16ITHg6 and am genuinely blown away by its power, however I was very un-impressed with the ram situation as I found the performance pretty unacceptable for the price of the laptop.

Before even receiving the laptop I purchased the G.SKILL RipJaws Series 32gb (2x16GB) 3200mhz CL18 DDR4 F4-3200C18D-32GRS kit to replace the stock Samsung DDR4 3200 CL22 RAM.

 

I read around for a while on unlocking the mythical advanced bios, tried all key combinations read every post watched every youtube I could find, all to no avail, it only worked on earlier models was the consensus. Then a random god send on the Lenovo forum sent me a link to a windows app that one click unlocks your advanced BIOS for most Lenovo laptops, within a minute I was into the advanced BIOS and boy are there a lot of options there! Including enabling XMP!

I hope this helps anyone else as it was driving me nuts having performance sitting on the table and not being able to use it.

 

EDIT: I have since changed RAM to Gear Mode 1 for better latency, 83.9ns down to 64ns and +2/3% read write speeds.

After using the one click BIOS unlocker for Windows the Advanced menu is available.

Finally having XMP settings and many many more manual settings (I ended up selecting manual everything)

The Stock Samsung DDR4 3200 @ CL22 RAM that came with the laptop - SLOW (Take note I updated BIOS and slightly different overclock from here on, it was unrelated and does not effect scores)

The new G.SKILL 3200 CL18 RAM with basic BIOS and default settings, laptop only allows it to run CL22+ with basic BIOS.

Hi, thx for this post. I have exactly the same RAM and the Legion 7i. I have the full blown i9 version. Unfortunately this "hack" is not working for me, I can't find the advanced menue after executing the Windows .exe.

On which BIOS version are you? I really want to use my faster RAM but im stuck with the original BIOS...Do you have any advise?

Solved: With the newest BIOS Version this hack is not possible anymore. Had to role back to the previous versions. Thanks 🙂

Hey! Sorry for the late reply, With tuning you can get the i7 to the same specs as the i9 i've got mine getting higher benchmarks than the stock i9 so id suggest having a good play with XTU! Especially undervolting CPU and GPU. Glad you sorted it out, There is a new BIOS out for this model that I havent tried yet, I'm still on C44W.

Thanks for manual, but could you please provide screenshot or BIOS settings to enable Gear 1 mode for RAM.

You have to do it in the RAM States, the lower 3 states (power saving) are set to Gear Mode 2 and the final 4th state (under load) switches to Gear Mode 1. The ONLY way i was able to lock it Gear Mode 1 was to set all 4 RAM states to Gear Mode 1. I will post a screenshot of this when I have access to my laptop again.

Got the Lenovo Legion 7i 11980hk working with XMP at all gear states. I also figured out how to RAID 0 the NVMe drives. Nice.

For the sake of posterity, i just tried the tool on my Legion 5 17.3" 17ACH6H, BIOS version: GKCN57WW, and it didn't work.

 

Edt: But it worked for this guy, so idk. > https://winraid.level1techs.com/t/tool-lenovo-h20-bios-unlocker-and-locker/38150/117
