I've been playing Starcraft II yesterday. My CPU jumps directly to 100°C and stays up there. and it goes immediately to thermal throttling. My frequency is at constant 3.9 GHz; which is good I guess. And frankly the game still runs smoothly. Every 30 min I undervolted my CPU to compare performances. I started at 0mv, then -100mV, -150mV, -200mV, -250mV through XTU. The performance is strictly the same every time. So I strongly suspect that XTU is not actually doing anything. I will try ThrottleStop today and see how it goes. 30min of Starcraft II I've also stress tested my CPU with different voltages ( 0mv, then -100mV, -150mV, -200mV, -250mV). Same thing here: he performance is strictly the same every time. Temps are at 90°C average peaking at 100°C. It thermo throttles immediately and then power limit throttles... CPU 30min Stress test All of this should not be considered normal right? What exactly is Power Limit Throttling? and should I get rid of it?

Thank you! As recommended I downloaded HWinfo. It works very well. But it does not show any changes on the voltage (screenshot below). Is it possible that XTU is actually doing nothing? should I try Throttlestop instead. From what I read, Plundervolt does not apply to AW M15 and i7-9750h, so this should not be the problem.

Here are the infos I got from the Intel website for my CPU: Processor Base Frequency 2.60 GHz Max Turbo Frequency 4.50 GHz From what I understand, this is the main indicator of the CPU performance. My goal should to have this value match my utilization. So the lowest possible when idle or on MS Word, and be consistently at 4.5 GHz while gaming. Is that right? So I need to find the sweat spot where the CPU undervolt does not impact my frequency. Am I making sense? Regarding the Vcore. How can I get the value, and what exactly I am looking for? Nothing called Vcore or Core Voltage appears in my HW monitor (See screenshot below). is the VID #0 the correct value here? I want to make sure that what I do on XTU has a real impact. Just to make sure: on XTU, the value I need to watch is the Max Core Frequency, right? What is the Processor Cache Frequency? And should I monitor this value too? the Vcore is referred as Core Voltage on XTU I should see a drop of 100mV on my Vcore if I go for a -100 mV Core Voltage Offset. Right?

Ok great thank you. So I should not be worried to have so much up and downs in the CPU temp. while gaming (SCII and Civilization 6 mainly) it stays at 95°-100°C though. I'll send a print screen as soon as I can. I'll try Vcore tomorrow morning and see how it goes.

HI everyone, I am very very new to the overclocking and undervolting world. So I come here with a lot of questions, hoping that you could help me understand what I'm doing a little bit better. Please keep in mind that I do not really know what should be considered as normal and what is alarming. I'm just guessing here. So my first question is: 1- What should I read/watch/listen to to learn about Hardware? is their any good online books, online courses, tutorials? I have a brand new Alienware M15 (full specs are listed below), and it's running very HOT. It used to BSOD a lot after a extended period of gaming. But after restoring Windows to factory settings I have solved the problem. I suspected that overheating was causing it so I installed XTU to track the temperature. My CPU runs at 49-55°C when completely idle. It is at 55-65°C while surfing on Mozilla and spikes instantly to 85 - 95 even 100°C for the slightest operation. I feel that this temp is very unstable. While gaming it skyrockets to 100°C and does not go down the 95°C mark. CPU Temp and thermal throttling while browsing the web (lowest 55°) So here are my questions at this point: 2 - Is the graph supposed to look like that? Is it normal for a CPU to lose or gain 10+°C every few seconds? 3 - what is considered a good temp at Idle/common use/Heavy use? for a standard gaming laptop? 4 - Same question for a Alienware M15? 5 - Should I be alarmed? 6 - is it normal to have thermal throttling? and power limit throttling? or should I aim to get rid of it? I thought of undervolting my CPU as it seems to decrease the temp and the throttle. but something weird happened here. When I undervolt on XTU, nothing shows up on HW Monitor. XTU and HW Minitor showing different Voltage offset 7 - Who should I trust here? I've read that HW monitor is very reliable 8 - Is the i7-9750H compatible with XTU? This processor does not show up on the official XTU download page (https://downloadcenter.intel.com/fr/download/24075/Intel-Extreme-Tuning-Utility-Intel-XTU) List of Intel processors compatible with XTU I have so many other questions (on the Alienware Command Center, power limit throttling, settings to lower CPU temp, the indicators I should follow etc...) but I have already been very long here! CPU: i7-9750H - GPU: RTX 2070 max-Q - RAM: 16 GB - Bios: Alienware 1.3.1 - OS: MS Windows 10 Family
