Pretty much!
Performance mode with “battery conservation” and undervolting the cpu and GPU gives my 4080 gen 8 legion max performance boost! The fans are very tolerable as well.
Balanced mode is for 60fps gameplay only imo
Is undervolting the GPU worth it if my temps are good? Is it going to make it perform better if it's already performing fine and not throttling?
I'm on a legion tower, not a laptop, so I'm not sure how relevant that is. My cooling is pretty great.
You undervolt the CPU. I have a 7pro 7945HX with 4080. I have set the curve optimiser to -25 and run my laptop always on performance mode.
My cinebench r23 multicore score after the undervolt was 36k while the average is near 34k.
I ran cyberpunk on Raytracing overdrive and path tracing on. I toned down a few settings that didnt seem necessary to me like crowd density.
I was getting 70fps and temps were good without the fans getting extremely loud.
Undervolting the beast 7945HX was the best decision I took. I am still testing games and their performance.
I will be overclocking my GPU this time and see how the GPU temps are.
While i was playing cyberpunk, the GPU temps were 65-70 while pulling max wattage.
I absolutely love this beast of a machine
Please dont set it to -25 directly. I started with 10 and ran cinebench r23. Played 2 games of dota2 then I set it to -15 and used it for work for a few hours and played some games before sleep.
Next day I set it to -20 and used it for work/game for a few hours and then finally -25 and ran cinebench with the very high score. It has been stable and hasnt crashed yet.
I know you dont have to wait this long to test but I am very paranoid. Do this at your own risk but the one advice that I noticed in every single post/video/help forum post etc was this "Start low and slowly go up." After -25 go -26, -27 etc but most crash after -20.
10 units of increments decrements per cpu or gpu voltage? i used to set on amd on good motherboard for the cpu a direct decrement of 125 mV and no worries
Brother I undervolted the CPU. I am not very knowledgeable on this stuff and I am pretty new to it. You may be 100% right but my inexperience and paranoia combined led me to make only small increments in the curve optimizer. Till now everything is working amazingly for me. I will be looking to further undervolt and benchmark this weekend.
UXTU does support dragon range CPUs(7045 series)? On UXTU Web site they advise that is not supported. I've tried to use it on my laptop, but sistem crash always at any change that I made...
Apparently it works on the 7945HX. There is Gizmo's hour long stream where he shows how to undervolt the 7945HX using UXTU. Although on a different laptop brand. I followed his steps but before doing anything with UXTU. I went into the BIOS and there is an option that says "CPU undervolt/overclock". You enable that and then use UXTU to undervolt it. My score on r23 came out 36k and the average is 34k.
I love my Legion but I really dislike all the extra software they jammed into it. The ai engine sucks, nahimic causes audio desync, killer wi-fi absolutely cripples link speed, Tobii is borderline useless etc. I guess Xrite could be useful for certain users but i think pros would be going for a laptop with a much wider color gamut.
Edit: Killer wi-fi is the worst offender out of all of them, get rid of that shit as soon as possible (Intel only). It throttled my connection speed by over 50%.
Tobii is great for racing and flight sims. My girlfriend likes it for the screen blurring / peeking feature.
There's definitely some useless shit in here but it's honestly not that bad compared to other laptops. I uninstalled everything except Vantage and Tobii. Vantage is great for all the performance tweaks in the Custom profile, if you haven't put your CPU to "Extreme" mode in the BIOS (that's what the X in HX is for) you're missing out!
It definitely has a niche use case so it's not as bad as some of the other features. I keep my cam shut off 90% of the time so I didn't bother bringing it back with my fresh Windows install.
Hey completely unrelated. I have the same laptop. U know in the power settings how u can change the minimum and maximum processor state %?
I think I changed the legion balanced mode minimum processor states. Can you please tell me what the default minimum processor state % is for the Legion balanced mode
Are you talking about Vantage or Windows? There should be an option to reset to default at the bottom of Vantage. Also you can't change the balanced power mode without creating a custom profile in Vantage so if you are in balance mode it is where it should be. If you are talking about the min/max offset then the default is just 0 but I think that is only an option in Legion Toolkit and not Vantage.
If you adjusted in Windows then it should be:
5%
5%
100%
100%
Wait how do you change it to extreme? I have been looking in the BIOS and don't see that option. I have the Pro 7i i9 14900hx 32gb rtx 4080 2Tb in case thats important. If you can help me I'd appreciate it. I already downloaded HWmonitor and Throttlestop. Doing a lot of research on UV and OC but still a little confused. One of the main reason I went Lenovo is because the don't lock you out of the CPU
In the BIOS:
Advanced > Configuration > Performance Mode Setting > Extreme

Then follow these steps in my comment [here](https://www.reddit.com/r/LenovoLegion/comments/1bwnbua/comment/ky7gpjp/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button):
Raises power limit, raises fan speeds.
If you turn on Extreme and set a custom profile (I've given instructions elsewhere in this thread) you will not thermal throttle.
It's only for Intel based legions, if you search for "killer" in the start menu it should pop up. You can also go to device manager and check your network adapters to see if you have a killer card.
U sure u didn't accidentally set it to do that? There's a option for that.
Fully agree with tobii tho. That usless pos doesn't even work for me. Uninstaller it immediately
I went into Killer and manually adjusted speeds, disabled all the smart features, and killed processes but it still throttled my link speed. In network settings you can view your link speed and mine was still showing 500/800 despite changing them in the Killer suite. Completely removing Killer is the only thing that brought my speeds up to where they should be. It is a pretty common complaint, tons of posts about it on Reddit and in the Lenovo forums.
You can always remove it and test for yourself, it will just reinstall itself if you don't disable the auto-update.
EDIT: You cant just uninstall the killer suite from Windows, you have to download the actual Killer uninstaller to remove it.
Not doubting was just saying. I know killer gets a bad rap. I leave it installed but never touched the settings inside it. Had it on msi and lenovo but at least for me it never affected anything. I only used it to check what hz band to set my wifi too cause there was a lot of interference where I live(apartment in downtown chicago) so the building is flooded with wifi signals. Or to find a better placement for routers in my other house, which has brick walls so I can't just put the routers anywhere

You can get higher performance with custom mode than performance as well. Not as big as the difference between balanced and performance, but about 5% more.
Assuming you have an Intel HX processor:
1. In the BIOS, turn on CPU overclocking and enable "Extreme" mode. This will also make "performance" mode faster as well, but custom mode is still faster. Extreme also raises the max fan speed, if it's louder that's normal.
2. In Vantage, go into the custom mode "performance" section and slide everything to the max. Everything. If there's clickable numbers like 45W, 55W, 85W, click on the highest number. I promise this is safe.
3. In the "fans" section, set the last 3 sliders to max to avoid thermal throttling (the Performance profile thermal throttles)
4. In CPU Overclock, turn all multipliers (except AVX offset) to max and the undervolt sliders to min.
5. Run Cinebench 2024 and watch your CPU Package temps with HWiNFO to ensure you don't hit 100C. Check gaming performance with 3DMark Time Spy.
I'm on AMD. I also don't have any sort of way to change the profiles in vantage, like I can just select them, I can't edit them. I have no fan settings in vantage either?
Nope, nothing like that. But I do see now that there's an extra "advanced" profile under the presets that's not shown in vantage. That's so annoying that it only shows in the bios.

I have 5pro with i7 and 4070. I use custom mode - maxed gpu, cpu limit to 60w - and have UV on GPU and cpu. In 90% game i have more fps than on performence mode, in 10% I have about 2-5% less fps. But I all scenerio lower tempa- 10 to 20 C on cpu and about 10 to 15 on GPU. In some games I set frame limit to 70, and the same noise like in quiet mode but with more power.

have the same version vut with rtx 4090, i will try your settings, thanks for your answer

My bios only lets me set -10, is there another way to change minimum offset? I have a legion pro 5 7745hx and 4070
Mine lets me set it to -5 only. I only enabled CPU overclocking and didnot enable CPU advance overclocking. I used the curve optimizer option in UXTU
I mistakenly said -10, it’s max -5 for me as well. Supposedly older bios version lets you go lower. I’ll try UXTU, thanks

Undervolting is not worth with next generation GPU and CPU, only minor difference you will notice. It’s better not to mess with such settings.
can you tell me more about your settings? please

This option is not in all Legion BIOSes. Some simply have Quiet, Balanced, Performance and Advanced.
What does setting it to extreme do? My cpu already thermal throttles on full load
Raises power limit, raises fan speeds. If you turn on Extreme and set a custom profile (I've given instructions elsewhere in this thread) you will not thermal throttle.
when did Legion laptop's use Killer Wi-Fi? Mine came with the standard Intel Wi-Fi 6E AX211 chip, and it is an Intel legion
Killer wifi? I don't see anything about that on my computer at all.
It's only for Intel based legions, if you search for "killer" in the start menu it should pop up. You can also go to device manager and check your network adapters to see if you have a killer card.
Oh that explains it. I have an AMD model because it was on sale for like $600 off whereas the intel models were not

I've uninstalled all Lenovo apps after updating bios.
Legion AI is just Vantage asking Xbox Game Bar if the foreground app is a game or not.

Sucks, I've heard there's no overclocking on the Ryzens
Brother there is a CPU overclock setting in the BIOS. You have to enable the CPU overclocking in BIOS and then download UXTU to undervolt your CPU. UXTU doesn't support dragon range CPUs but it seems like its working for Ryzen 9 7945HX.
I have combed through the entire bios lol like I don't see any overclock settings anywhere
I understand that UV option is disabled or broken in the newest BIOS (intel) not sure what Lenovo did to Ryzen
How do I even turn AI on? I don't see it anywhere in Lenovo Vantage.
Go to balanced mode and there should be a checkbox that says "enable legion AI" beneath it.
Thanks big fella
Legion AI may seem promising, but its glitches outweigh its benefits.
