@kotlos @whiskey_1130 Have you'll tried undervolting as well? Don't have the 2018 Macs to test, but on my 2014, I could undervolt the CPU (i7-4870HQ) up to -60-75mV - pretty great. Combined with Macs Fan Control, one could have some notable gains in general performance. Now if there was a way to undervolt discrete GPUs as easily...

I tried to undervolt with the Volta app but I don't think it is actually undervolting since there is no difference in performance or W/Hz. I remember when undervolting the XPS 15 I could get few hundred MHz more for the same wattage but with the MBP it is the same.

@kotlos Seems like undervolting is likely not supported on the 8th gen chips in Volta. I was able to crash my system by going too negative -  so it's clearly working on older archs. Dev will likely add support soon (hopefully).

Wow I had no idea this was an option on apple devices... I always thought you could only mess with CPU clock/ voltage on pc/hackintosh. For the above examples are people raising or lowering total watt draw/ TDP?

I just used a software called Throllingstop and I could indeed mess with voltage and locking a frequency. Tried locking 3.5ghz on a 3.1ghz 2017 mpb while gaming, worked for a while but temps were hitting 100 degrees so it froze. Back to factory settings, I tried undervolting .90 but I couldn't eyeball any FPS improviment. Will do further testing though.

Do the tb controllers connect to the cpu or dmi?

kotlos - How did you setup up the MBP 2018 with BootCamp and the 1080 TI. I keep running into issues and can't get it to work correctly in Windows or Mac without errors. 

Thanks

It's an ULV processor so the TB3 controllers go through the PCH.
