Undervolting latitude 7390 i7-8650u?

Wondering if anyone has some advice on what values to start with undervolting on the 7390 i7 8650u?

 

Sadly I do not, but I will tell you my experience with lower power CPUs means you have to be more conservative. The couple of i5-8250u processors that I've had it a max of 65mv and 70mv. I would try around there first and then test it out. It doesn't seem to be a problem with the maximum frequency but as it changes load. One thing I would do is run prime95 for a couple of minutes and then stop the test and wait for a minute then repeat that process 4 or so times. You'd be surprised how many 12+ hour prime95 stable undervolts I've had that will fail this test.

AIDA64 is also a good test to run since it fluctuates the load a little bit.

 

I have it stable on - 90mv. Tested over last 5 days, mostly gaming on egpu

@baalph, you have a 7390 also? How are the temps of cpu while gaming on egpu? I got myself a 7390 and that's what i aim for.

 

Yes. I use custom performance mode for battery and it allows me - 130 undervolt. In most of the games I have stable 3.8-3.9 frequency. I use it with 1080ti which is overkill tho.
