Alienware 17R4 CPU & GPU undervolt to help improve thermal
Hi, I have an Alienware 17R4 (I7 7820hk & GTX 1080) and I would like to ask if any other users is doing undervolt on their CPU and GPU. If yes then what are the numbers that you've found to be safe?
Personally I manage to do -0.145 on CPU at 4.0Mhz and 850 on GPU at 1822Mhz(with MSI afterburner). I also lower the maximum GPU clock speed to 1822Mhz (Originally it was set at 1903Mhz). The result was amazing with no performance lost in gaming, completely stable system and the CPU temperature improve by 10'C, GPU temperature improve by 5'C.
The only problem that I find( which is not really a problem) is that the undervolt value in XTU seems to reset everytime I restart the system, which doesn't happen on any of my other laptops/ desktops. I did some research on Intel forum and they claim it to be a problem with the manufacture bios (in this case Dell) and there's nothing they could do.

That's a nice decrease in temps!
Why don't you give throttlestop a try? It has a lot more functionality and you can make it boot with your settings. There are plenty video tutorials on YouTube.
