Undervolting? How does it work?

[Joey96]

Hey guys!

 

I just received my new Razer Blade 15, and was wondering how to undervolt this sexy beast to get better battery life? 

Does anyone have a guide or some steps I can follow? I haven't had anything done with undervolting, so I'm on very deep waters here

 

Thank you in advance!

download intel XTU (extreme tuning utility) and under the voltage you can dial it down from 'auto' to 0.005, and it'll go down in 0.005 increments. 

skip to 0.05, play some 4k 60fps youtube, maybe a game, if it remains stable after 15 minutes go down to 0.1, then try again. If it still works then keep doing the same but go down in 0.005 increments instead of 0.05. 

 

we start out at 0.05 and 0.1 because almost every CPU can go down to at least -0.100mv. anything more and it'll get dicey depending on your CPU and so 0.005.

So I would dial it down, and then test it with a benchmark? What would u recommend?

test it out with some real world usage, or a benchmark I guess. prime95 works too but monitor your temps because it's prime95.

Thanks for helping man! Is it supposed to go BSOD or something when unstable? Is my goal to get as low as possible here or?

yes, it's supposed to BSOD when unstable 

the goal is to get as low as possible with it remaining stable, less voltage = less wattage = more battery life because less wattage being used by CPU

Alright ill start trying that, I've read that throttle stop i supposed to be better than XTU? Any opinions on that?

XTU has a easier GUI to do things in and to learn

since you're figuring out how much can you undervolt, just use XTU to figure that out, then you can apply the undervolt in throttlestop

 

also yay 11k posts lol

Yeah I did realize that when I first installed throttlestop.... and yet i still dont know where to apply the undervolting on it :7
