Hey there as many of you possibly read, there is a method of increasing the performance with Volta by limiting the TDP at 45Watts, the thing is that Volta doesn't support undervolting in Coffee Lake, so I want to ask you guys to try the program I'm using to undervolt my Kaby Lake Hackintosh Laptop, Voltageshift, it doesn't have a pretty UI, and is run from the terminal but it may work at undervolting. I would be grateful if you could please try undervolting, and limiting the TDP and post your Cinebench scores and Intel Power Gadget.

Instructions and Download:

-130mV(Cpu) -90(iGpu) is what I use, and sorry for spamming this program, I'm currently eyeing the MBP 2018 and want to know how much juice we can get from the beast.

The issue here is they already have Volta, you joined yesterday as a newbie and already posting links to an app. That is a security issue. The random looking site you linked to says the app is hosted on Github but on that site there are no releases. I would avoid your download.

I understand your concerns, i'm a newbie here though I was quite a lurker before and read all the threads about the MBP, and nobody seemed to sugest VoltageShift, that's whay I registered. Volta is working only as a TDP limiter, the undervolting is not working, that's why I'm posting voltageshift as I know that in my hackintosh laptop is working and getting nice results, you can download and compile it yourself if you are worried about this being malware. I just want to know if the 2018 MBP can be undervolted and get the best performance out of it.

So compile the app on Github and don't be so anonymous online if you want people to open your software. You have no bio on any of your links and the Github has no direct commits:

lol is not my app I can compile it for you, but really I'm not a programmer. I tried pulling a request to correct some English Mistakes, but the dev never answered.

edit2. I can make a short video for you to see the package power being affected before and after the undervolting using VoltageShift

That's even worse. If you can't confirm the executable comes from the GitHub source code then you might as well be posting malware.

The link I posted is from the readme of the github repository.. anyway that's your choice :shrug: I just wanted to help whoever is interested in getting more performance out of it's MBP 18
