First of all, I want to thank the author for this amazing utility!
I didn't have so much fun since the early 2000's when I was frying my memory at 4V with 2-2-2-5 latencies
I wish there was a comprehensive guide explaining all the parameters in details but a bit of googling solves the problem.
Here's my situation:
I have i7-9750H on Eluktronics Mech-15G2Rx and I'm quite happy with it.
But I'm not satisfied with the battery life so I've decided to thinker with it a bit.
Turns out that pumping up is much easier than toning down.
The processor itself seems to be quite good and I was able to undervolt it quite a bit.
You can see the results and settings on the screenshot.
What surprised me is how hot is the cache memory and it's effect on the TDP since, for example, reducing the voltage for cache from -140 to -190 reduced TDP from 68W to 60W while reducing the core from -250 to -300 (not stable) had almost no effect on it.
But I'm not working on anything very computationally demanding so this is not such a big deal for me, and I would keep processor's TDP much lower for gaming since 1660ti is quite power hungry as well and it has a much bigger impact on the performance. When you have a laptop you have to make a compromise.
The main goal is to make a battery saver profile as efficient as possible.
First, I've replaced my Windows 10 Home edition (that comes preinstalled) with Win10 LTSC 2021 to reduce the amount of unnecessary MS crap to a minimum.
Then I tinkered with the services a bit more and I would say I did a good job.
However, something in the Speed Shift implementation seems to make a difference in the C0% when processor runs at max (0) and reduced (200, see screenshots)
At 0, C0% is at 0.1-0.2%, but at 200 it goes up to 08-09% and if fluctuates quite a lot. All the parameters are exactly the same, except the Speed Shift.
Why is this happening?
Try as I might I was not able to reduce this.
Also, on the Windows Home edition the idle TPD would go as low as 0.4-0.5W, but here it never goes bellow 1.6W.
Looking forward to your advice!
Cheers!
