Good day to all,
This is my first thread (don't know if this is the right section) and i am posting it because i have a problem… of course
My laptop is a MSI GF63 thin 9RCX with a I5 9300h and a GTX 1050 TI max-Q.
I was beginning the process to undervolt with THROTTLESTOP the CPU to obtain better thermals, battery and all the good stuff, so i go and set some benchmarks (with both tsbench and ) and here i noticed that sometimes the CPU was power limited at 25W.
After some testing, I come to the conclusion that when the dedicated GPU is active, for example when NVIDIA control panel is open, something (BIOS, Firmaware, i don't know) limits the power of the CPU to 45 and 25 watts for the short power (28 seconds) and long power respectevely.
Consequently core clocks plummet and sometimes even below the base clock speed. TDP of the CPU is 45W, of the GPU is 46W and the power brick is rated at 120W, so i don't understand why this happens. This obviously not good for games… i think.
Thermals should not be a problem, temps at 45W are well below 80°C and around 72-74°C, fans are not even at 100% so I image there is some headroom.
Now,:
Is this normal? Is there some way to bypass this? Or at least raise this 25W limit a bit?
All this is done with AC connected, fresh install of Windows, drivers and bios updated, nothing touched on Windows power settings or TRHOTTLESTOP settings.
I should also specify that I am an engineering student and i will use this laptop (primarely) for code writing, computing and multy-body systems simulation (which requires both CPU and GPU), but gaming (on a budget) too
Thanks everyone
