Lenovo Legion 5 and 7 (2020)

Can anyone with an external monitor confirm this issue please: http://forum.notebookreview.com/threads/lenovo-y540-main-thread.829600/page-10#post-11061774

 

for anyone unsure of how to teardown/assemble/replace parts, lenovo has official part replacement videos for everything from the bottom case removal, lcd panel, motherboard, etc...

The coldplate that cools VRMs and VRAM, is it aluminium or steel? Or nickle coating?
@dglt how did you apply LM and what precautions did you take?

 

Aluminium, don't touch it with LM

 

like seanwee said. its coated with something but its still aluminum underneath so keep the LM away from it

 

i can confirm that two nvme and one sata3 ssd will work fine. disk0/disk1 are nvme, disk3 is sata3

 

This^

The cooling system is already great so doing a repaste with good quality thermal paste will be more than enough if you want

 

Good news. Did you manage to fit them all in or is that just floating in the air?

 

the 2.5" ssd i removed the casing, ran the cable right under the second nvme, covered the metal where i mounted it with electrical tape for now but i ordered some thermal tape i can use to better mount it and get that elec tape out of there. i only did a quick aida64 read test on the second nvme (wd black 1tb SN750) but read speeds over 3000mb/s so all seems to be working well.

to anyone familiar with RAID0, is there a way of making my two 1tb nvme drives RAID0 without having to format the original nvme?

edit: @Tadician , i'll grab a few pictures when i go in to mount it with thermal tape

 

Pictures would be great, thanks.
I think there is no way around formatting for RAID.

 

i looked for a way around it but i guess not, i have to backup some stuff and i'll set it up later. i just got done modding the latest 45WW bios, everything looking good. the 45WW adds the overclock feature to vantage, not that i'd actually use vantage to overclock the gpu but its good lenovo added it to the intel models.

i also figured out a much easier way of enabling undervolt using H2OUVE from cmd prompt, no RUefi necessary. i'll post the guide here in the next post

 

ENABLE UNDERVOLT GUIDE:

H2OUVE(needed for edit): https://share.unixfy.net/insyde-tool.zip

Code:

1. make sure your NOT using EFCN39WW bios.  38WW and 45WW(latest) work fine with this method but 39WW does not. and make sure secure boot is disabled from bios.
EDIT: EFCN46WW has lower PL1/PL2, if performance is the goal stick to 38WW or 45WW

2. download the linked tool and extract to a new folder C:\insyde-tool  after you do that, open a cmd.exe prompt as administrator  then enter

cd C:\insyde-tool

3. then enter command dir to confirm your in the right directory, you should see multiple files including "H2OUVE-W-CONSOLEx64.exe". once your there, run the following command

H2OUVE-W-CONSOLEx64.exe -gv vars.txt

4. that command should create a file named "vars.txt" which you'll now open with notepad to edit. CTRL+F to search for "CpuSetup". i'll include a screenshot of the value your changing, all your doing is changing
the  01  to  00

5. after changing the value thats highlighted in the picture, save the file as vars-m.txt in the same directory and you can close it after it's saved

6. go back to the same command prompt and run this last command and your done, reboot and you should have unvervolt working after a reboot.

H2OUVE-W-CONSOLEx64.exe -sv vars-m.txt

Written by dglt

bit to change when editing vars.txt which is 0xDA, change from 01 to 00
https://imgur.com/a/KDvF5si

Code:

when you run the last command, what your looking for when it outputs a bunch of "failed" and "success"

outputs is the value shown here next to CpuSetup   and you want to see "Success".

reboot after, undervolt should work via throttlestop.

EDIT: above note to avoid 46WW

 

Hey everyone, just got one Legion 5 (4800h/1660ti/144hz) and one Legion 5i (10750/2060/240hz) for my cousins, I think I am more excited than them

Wanted to ask about a couple of things if possible:

AMD based system:
1-Can I use Freesync in D-GPU mode? or I need to be in Optimus mode?
2-Should I use the AMD gpu drivers on Lenovo's site? or just update from AMD's site?
3-I remember reading about a tool like Throttlestop for AMD cpus what was its name and how to use it (A guide if possible)
4-Any tips and tricks to maximize the performance?
5-Can I tweak the memory in this machine?

Intel based system:
1-Read that someone activated G-sync (Is it compatible with this panel?)
2-What is the best way to enable undervolting and what is the new general stable undervolting value?
3-Has anyone successfully flashed a 115w Vbios on the 2060? (Saw someone that said it worked but only in optimus and not D-gpu)
4-Can I tweak the memory in this machine? (Had a lot of fun with my MSI GE75)
5-Any tips and tricks to maximize the performance?

Sorry for the long list but hopefully after some time with these machines I will be able to share some new info (Hopefully) and help around

Thanks

 

i'll answer what i can.

AMD based system:
1. no, freesync is enabled by the amd driver. nvidia doesnt see this as a g-sync compatible panel.
2. probably the ones from lenovo at first, they pack other things like icc profiles, inf files for the display in the same package sometimes. after that you can update as you see fit from wherever you want.
3. ryzencontroller
4. ??
5. ??

Intel:
1. i have the 17" 144hz 300nit panel and yes i've gotten g-sync to work on windows in the past but im unable to reproduce this, its not intended to work on windows or linux but on linux im able to use g-sync and this panel is well capable of it and works amazingly well. for linux g-sync i had to modify the EDID from the panel, add variable ranges and adjust clocks and then use an EDID override via the nvidia driver.
2. i posted a guide here a few posts back, that is the simplest/easiest way of doing it at the moment. the RU.efi method works too as well but its not as simple. on the i7-10750H i think a safe starting point of -115 on the core and -90 on the cache would be stable but undervolting is not one size fits all so you'll have to see for yourself how far you can go and still remain stable.
3. yes, i've posted the 100w vbios from the Legion 5pi and the 115w vbios from the amd legion 5 here in this thread somewhere and i can confirm both work with hybrid and discrete modes and all external ports remain working. there's a few people that said the 115w vbios has random changes of backlight while using hybrid mode but not on discrete mode where it works 100%, the 100w vbios has no reported downsides that im aware of.
4. yes, how far you want to go is up to you. i have a modded/unlocked bios and about 843590438590348 extra settings i often find myself getting lost in , its great.
5. undervolt, paste(or LM if your comfortable), 100w/115w vbios.

 

Thanks a lot for the Info, will check around if I can find the 115w vbios.

Oh boy the reason I sold my GE75 was the lack of tuneability even after unlocking the bios (Got a 5950x and a 570x unify) was a tweaker's heaven, I am sure I spent more time in the bios than in the OS it self before selling it (So the "843590438590348 extra settings" is where its at )

Thanks again.

 

its a laptop, you'll never get as much tunability as you would in a desktop but you cant knock a person for trying

 

Wanted to ask, what is the method used to flash the 115w bios and if you can share it as I couldn't find it.

Thanks

 

this is a zip file containing the tool (nvflash), the 100w vbios from 5pi, and 115w vbios from legion 5 (amd)
https://share.unixfy.net/nvflash-legion5-100w-115w-new1.zip

GUIDE - FLASHING 100w or 115w VBIOS only for the RTX 2060 (2020 Refresh Model)
1. extract contents to C:\
2. open cmd as administrator
3. run these following commands

Code:

cd C:\
#this makes backup of original
nvflash64_patched_5.590.0.exe -b original-vbios.rom

#this flashes the new vbios, first command is for the 100w vbios, seconds command is for 115w. *CHOOSE ONLY ONE*
nvflash64_patched_5.590.0.exe -f -6 legion5-rtx2060-100w.rom
#OR
nvflash64_patched_5.590.0.exe -f -6 legion5-rtx2060-115w.rom
#answer yes to both prompts

4. reboot and your done.

 

Hey @dglt I just finished repasting (For some reason the paste was hard as cement had to scrape it off) flashed the 115w bios and seeing 1700-1900 on the clocks, just wanted to ask what can I expect out of the memory on this 2060? my 2070 on a ge75 was able to hit +1000 with no issues or performance loss (As these are ECC).

And how can I confirm the undervolting is working using the H2OUVE method, it shows - offset in throttlestop is that it?(First 10th gen cpu) + I was not able to access the advanced bios at all any tips?

And last but not least, the long PL is stuck at 45w any way to raise it? TS doesn't seem to work.

Thanks

EDIT: TS is working for sure already crashed once with -100mv so back to 80 it is.

 

Hi, I have Legion 5i "i7-10750H / RTX2060" for a few days.
I have observed that temperatures are high, at full load Clock above 4.3 Mhz During heavy games, using FN + Q
Automatic mode is around 82 degrees with fast 90 degree spikes
Performance mode goes up even further, staying around 85 degrees and peaks of 96 degrees.
To get around this I changed in windows power settings, the processor frequency to 3600Mhz the temperatures dropped to about 75 degrees.

1 - Is my equipment having a problem?
2 - Is it possible to make a backup of the bios before modifying?
3 - If I do undervolting, when installing a new version of bios do I lose the unlock?
4 - Is it possible to downgrade bios? How to proceed?
5 - If something goes wrong during the undervolt, is it possible to restore the bios or something?

Sorry for so many questions, I don't have much experience.

 

1. no, if you look at other laptops with the same specs the temps are even higher.
2. yes, you can use intels firmware flash tool FPT to dump the bios but you wont need it. the edit i posted is easily reversed with a cmos reset or reinstall of bios via the normal lenovo exectutable.
3. yes, updating bios reset the lock bit. also, i strongly suggest you skip the EFCN46WW bios update. 45WW is fine but 46WW was a real screwup by lenovo and the power limits are locked to 25/45
4. yes, in your bios you enable "bios back flash" first so it allows earlier bios versions.
5. nothing should go wrong, there is no guessing involved but if it does a cmos reset will reverse the bit. the bit being changed controls "Overclocking Lock" which is located in advanced bios which you cant access unless you have an unlocked/modded bios. 01=enable and 00=disable. disabling the lock allows for undervolt

 

for benchmarks the highest i go on the memory is +1000, over that tends to have a negative effect. for gaming i usually have it set to +800

 

Thank you for your help.
It clarified my doubts.
I will perform the undervolting procedure.
Thanks

 

Your tips were precious, everything went well for unlocking.
Can you tell me if unlocking to adjust the voltage can cause any problems?
Can Plundervolt cause any problems now that undervolting is unlocked?

 

i wouldnt worry about plundervolt on a personal laptop and other than that just adjust your undervolt and make sure its stable and your fine

 

Anyone getting an issue where when the screen times out and you have to hard reboot the computer to have the display come back on?
I believe it may have been because I updated to Nvidia's newest driver (for Cyberpunk) instead of the Lenovo driver but figured I would check with you all

im running latest drivers as well, no screen blanking. hybrid or discrete mode? im on discrete

 

Was in discrete mode. Will check hybrid and see if that makes a difference.

Edit: yes, hybrid mode has it work perfectly again. Don't know why discrete mode messes with waking the screen...

 

Thanks.

 

What before and after temps are you guys getting after repasting the 5i? Any Idea where I can download the 45ww bios version?

 

improved temps from repasting depends on how good/bad the factory paste application was and how well the heatsink fits, i think @seanwee did a comparison including the new formula of mastergel maker and showed it outperformed all the top pastes (kryonaut,kpx,etc...) but i cant seem to find the link so maybe he could chime in. i never tested it myself but i see no reason to doubt his word on it

download link for EFCN45WW : https://download.lenovo.com/consumer/mobiles/efcn45ww.exe

 

I tested it on my Zephyrus G. And yes, it outperforms all other high end pastes but not by much, like 3-5 degrees compared to other high end pastes like Kryonaut, Gelid GC extreme and KPX. Longevity seems ok as well as its been 8 months and the temperatures have been stable unlike Kryonaut which started climbing in temps after 3-4 months.

 

as far as thermal pastes go 3-5c cooler than the best competitor is a lot, thanks for clarifying

 

Hi, If dglt or anyone can answer.

1 - Is there a way to access the advanced Bios in Legion 5i, is there Bios Mod for this model?

2 - I am confused, some users say that Bios 46ww is better than Bios 45ww, it improves performance.
In my equipment the TDP of the processor generally remains between 25-30W and has peaks of 50w;

The PL1 and PL2 on the 45ww are:
25 / 45W in economy mode;
70 / 80W in balanced mode;
75 / 107W in performance mode.

It seems to me that 46ww "limited" to PL1 and PL2 at 25W / 45W for all modes. That's true? What happens?

2 - My legion 5i on the GPU reaches 85W.

I would like to install the 100W vBIOS for better performance.
Would it be possible? 100W higher performance?

Where can I find the 100w vBIOS through the "original installer"? does this version exist?

 

1. on the Legion 5i you can only access the advanced menus with an unlocked/modded bios.
2. maybe the people saying 46WW improves performance have a different idea of what performance is, for me it means performance as in more powah! (not longest battery life because of a crippled TDP)
2-2. linked zip file contains 100w vbios from the legion 5pi, the 115w vbios from legion 5 (amd), and nvflash.

edit: here, vbios and guide i have posted here http://forum.notebookreview.com/threads/lenovo-legion-5-and-7-2020.832593/page-27#post-11063465

 

Thanks!

Taking advantage, the easy method of undervolting using the cmd you posted can be used for any version of bios. For future versions that you saw, can we use this method?

 

as long as "Overclocking Lock" remains at 0xDA in CpuSetup yes. it should, its been at that spot since 32WW up to 46WW

 

for the adventurous people that know how to find/extract IFR from different sections, that same method can be used to change a number of different settings

 

Hi guys, is there any method to UV ryzen 4800H?

 

i dont have any experience with that cpu but i usually hear people saying you cant or shouldnt undervolt them. could be wrong, just mentioning it.

do you already have this? https://www.ryzencontroller.com

 

Yeah, you can't undervolt ryzen mobile. The only thing you can do now is to change the power limits.

 

The verdict is in. Both 240hz and 144hz HDR400 display options are nice but the 144hz is superior in color reproduction(wider color gamut) and image quality. I have just replaced the Legion 7 that came with the AUO 240hz to the BOE 144hz and I was blown away on how much better it is. Not only that is able to produced more colors but the quality on the Matte overlay is far better than the AUO matte overlay. In fact, the usual downside with AUO display panels is that the matte overlay it uses always produces more grainy, sparkle, and shimmer effect especially on whites.

You can argue that the 240hz is a tad bit faster but it is negligible at best and it isn't worth the trade off for a better image quality that you'll get with the 144hz. I have gone through many displays and this BOE 144hz hdr400 500 nits is the best FHD screen to date.

 

Found a AMD Legion 5 with the same specs as the one im using but with a RTX 2060

https://www.amazon.com/Lenovo-Legio...words=legion+5+rtx+2060&qid=1608601623&sr=8-6

I think Intel models cost around the same price as well.

Sadly this

But if you're concerned about temps you can disable the boost which will keep the CPU at stock speeds.

 

Heresy

 

You can through the registry. I found the tweak on reddit months ago but here a video of it



Personally i only disable it on battery inorder to increase battery life.

 

I picked up a Lenovo Legion 7i 15IMH05 (81YT000RUS) yesterday and am having problems with getting G-Sync working.

This shows the display has G-Sync - https://psref.lenovo.com/Detail/Legion/Lenovo_Legion_7_15IMH05?M=81YT000RUS

• Display 15.6" FHD (1920x1080) IPS 500nits Anti-glare, 144Hz, 100% Adobe RGB, HDR400, G-Sync, Dolby Vision

However, it doesn't show up in the Nvidia Control panel - https://i.imgur.com/WR59V4q.png

The panel is showing a hardware ID of BOE08EA and this Reddit post shows that panel supports G-Sync - https://i.imgur.com/iGbI4xI.png

I have the BIOS configured to "Discrete Graphics" - https://i.imgur.com/KOQGvbv.jpg

Lenovo Vantage shows Hybrid mode disabled - https://i.imgur.com/CXcnK5N.png

If I connect an external Asus ROG monitor with a USB-C to DisplayPort cable, the Set up G-Sync option appears but when I disconnect the external monitor it goes away - https://i.imgur.com/eJzMNnN.png

I opened a support case with Lenovo and they remote controlled my machine for an hour and said they'd have to send a tech out to replace the panel or I could return it to CDW.

Is there something in the advanced BIOS that would need to be configured? Or something special I have to do to get it working? Can anyone help me out?

 

Be kind enough to share what you find out because I also have the same issue with the same display. I remember reading it somewhere that someone had to do a clean install of windows and drivers to get it to work.

 

That was the first thing I did when getting the laptop. I cleaned the drive and installed 20H2 and then drivers. I reached out to CDW so they could clarify if this model actually has G-Sync or not. The sales page doesn't show G-Sync but the psref page does so it's very confusing.

https://www.lenovo.com/us/en/laptops/legion-laptops/legion-7-series/Lenovo-Legion-7/p/81YT000RUS

Display Type

15.6” FHD (1920 x 1080) IPS, anti-glare with Dolby Vision™, HDR 400, 500 nits, 144Hz

 

I think they are locking the G-sync in Legion 5s to not compete with their L7 lineup, because if you have a 115w 206, gsync on a wide gamut screen with either a 4800h or a 10750h then you are as set as it gets and won't even consider an L7 2070mq model for nearly double the price.

 

CDW told me they couldn't help me since it is a consumer model and all of their Lenovo connections are with the enterprise channel. I'm going to call support today and see if the person on the phone is more competent than the guy in chat who remoted in my machine.
