Hello. So first off i have a gaming laptop with the specs: i7-9750H, 1660-TI and 16gb ram. I've had issues with my temperatures and very recently came across undervolting. I've since been trying to undervolt both my GPU and CPU since it tends to get quite hot unnecessarily, as in just running the browser or heats up too fast in games. I've been using MSI Afterburner and ThrottleStop to lower the voltages, and in the beginning i could do it. Nothing happened after changing it except the occasional bluescreen where i then added some volts to afterwards. But now, after i do an undervolt on both of my parts my applications, specifically my games, start to not work properly. I tried launching Assassin's creed unity and it froze right before getting to the main menu, and sometimes it would freeze the entire system with the cursor instead of giving me the option to close it which would then require me to turn it off with the power button. i tried it with Batman: Arkham Knight aswell and got the exact same response, although there was something interesting about it since a message pops up talking about something from june/july 2012. Not sure what it is about. i did however also try Portal 2 aswell and that started up, but as soon as something a little more demanding happened (hitting the blue gel liquids) it froze and required the same procedure as before. All of this hasn't happened before and i've done a couple forced shutdowns but i dont want to take the possibility of damaging it further. After these problems i set all my setting to stock again and then it ran as it did before the settings. My question is, is there some sort of option that's causing this? And am i not supposed to undervolt them both at the same time? And how big of a correlation is there really between the GPU/CPU? as in, do they need to be the same values or can they be different values?
