hi i managed to undervolt cpu through "voltageshift" getting much lower temperatures and consumption. I have set offset a -150 for cpu -90 for gpu and -150 for cache memory. the battery lasts a lot longer, the performance are much higher. voltageshift.zip I have created two scripts, they must be modified with your login password. The voltageshift folder should be copied into downloads. My xiaomi is the core i5 mx150 with bios 603 and patch for undervolt.

After you downloaded the binary you need to change the file permissions by running the following command in terminal: sudo chown -R root:wheel VoltageShift.kext

Nice Job! I currently don’t have my Xiaomi laptop. I will test it as soon as I get my laptop.

Seem awesome! Can you share the battery life before and after undervolt, I will try it when I have spare time (have no time to fix for "non stable" crash D;(just recovered from time machine due to macos upgrade problem(freeze or fake black screen after clover when updating(I may have abused parentheses ))))

Also does this work for i7 model?

Also does this work for i7 model? works with cpu intel Haswell / Brodwell and kaby lake. In my case I managed to reduce the mV of 150 for cpu and cache, while for the gpu only 90mV. Each CPU is a case in itself. If you set it too low the system will freeze, please turn OFF completely and turn ON computer to reset back the undervolt to 0mV.

after 10 minutes I unplugged the battery charger signals me 6:32 of autonomy

[fladnaG86]

:)

[fladnaG86]

after about 45 minutes of browsing on safari some benck with cinebenck gives me again 6 hours and 48 minutes of autonomy

ho capito come far partire lo script ma non come installare il file .kext, potresti aiutarmi?

[fladnaG86]

sure to have unlocked undervolt on the bios? You have to use the patch for undervolt bios https://github.com/stevezhengshiqi/XiaoMi-Pro/issues/8

Undervolt does not work for me, while I use the identical processor, i5-8250. VoltageShift is owned by root:wheel but voltageshift offset - leads to a 0 mv before and after voltageshift. Has anyone made it work? I'm using OS High Sierra by the way.

it prompted me that my password was wrong before I entered it.

[Menchen]

Change the password inside that file, or run that command directly with sudo

@fladnaG86, can you help me with the procedure? This is my first Hackintosh; could you explain the procedure in detail? this is my telegram account @sasi_95 if you want to contact me in private (I'm italian)

what should i do about the kext should i copy to C/K/O or delete it?

[MarFre22]

@fladnaG86 , thank you very much for your scripts!

@Parthvsquare , I made a automator's app that, automatically, during the boot, open the "voltage set.command" script. It's working and I don't need to add that kext (that can make EFI unstable). Here https://github.com/daliansky/XiaoMi-Pro-Hackintosh/issues/389#issuecomment-626885056, you can download this app.

I hope I’ve contributed.

i am still having higher temps

[MarFre22]

@Parthvsquare Assuming you made an stable undervolting (use the info script to verify that), you can activate Speed Shift which is nice feature to have, I feel it gives more performance in daily use. Also It can be related with the thermal paste, I'm using Thermal Grizzly Kryonaut, or general clean. Or you feel that you have the same high temps than before, but now you have more GHz (a bit more performance). In extremely cases, I hope not, it can be a sporadic bug on the bios, try to reinstall.

When I said that I have better temps, I'm not saying that it's colder at max load. Because in max load the internal and external temps are the same but I can have more performance (2,09GHz -> +-2,37GHz).

I hope I could help, because we have many variables related with temps.

[Parthvsquare]

OC mailbox cmd failed? will there any problem

[MarFre22]

@Parthvsquare, Not a problem, it's fine, you activated the undervolting. Mine is the same as yours: I tried and I can safely change the values to -110 -75 -110.

[lloydeeaquino]

Hi why mine showing temp at 96C?
