Hey everyone!
First of all, thanks to @unclewebb for updating ThrottleStop to 9.5.1 and adding support for 13th Gen Intel CPUs!
I have an ASUS Rog Strix G18 with Intel Core i9-13980HX CPU and am using ThrottleStop to undervolt it.
So far, I'm getting a stable undervolt @ 85 °C average / 92 °C max with a 30 mins Cinebench R23 pass / 1 hour gaming session and the following settings (see screenshots below for additional details):
CPU Core: -139.6 mV
CPU P Cache: -110.4 mV
CPU E Cache: -110.4 mV
Thermal Velocity Boost: NO
PL1: 80 (Clamp)
PL2: 80 (Clamp)
Sync MMIO: YES
So, as I understand from seeing other people push their 13980HX much higher than this, I probably didn't win the silicon lottery. I got a 27300 score in Cinebench with these stable settings. The max I got was 34000, but the CPU got unstable after a few passes. My laptop feels really snappy in general, so I am still happy with the results.
Now, I have a few questions, and I hope some of you might be able to answer them.
1. Unervolting the CPU E Cache seems to have no effect at all. The CPU speed doesn't change and my score in Cinebench stays the same. Is this the intended behavior? Is there no purpose in undervolting the CPU E Cache?
2. A few years ago, when I undervolted CPUs, I would see the temperature dropping. Now, when I undevolt this CPU, I notice the temperature stays the same, but the speed of the CPU (MHz) increases. Is this normal? Is this a new behavior from undervolting? Maybe I missed something?
3. Again, a while back, to find the perfect balance between power and heat, I would undervolt the CPU and adjust the Turbo Ratios until I found the sweet spot. Now, I've done things a bit differently and have been adjusting the CPU's Turbo Power Limits (PL1 & PL2) to find the sweet spot. According to you, what's the better way to proceed? Turbo Ratios or Turbo Power Limits?
4. Would anyone have any other advice or recommendations regarding this undervolt?
