I've been having a hard time with the new XPS with i9 processor: it just overheats gettting close to burn my hand after hours of working. I'm a software engineer, so, there is no option for me other then work to get paid, and this means typing a lot.
The CPU temperature were going really high here degrees Celsius. I just couldn't work anymore as my hands were literally burning specially the left one. After some online research, I found about a technique called Undervolting. The processor, obviously, is an eletric device and the more processing it does, the more power it needs. And the i9 processor does it really well, getting over 4. Everybody knows that. So, undervolting basically means reducing how much energy can be sent to the processor at once.
Intel Extreme Tuning Utility (XTU) Undervolting Guide
That did not only made my processor to stop burning like crazy, but also make my battery life longer!! On Linux now, using the NVidia driver but setting it to use Intel with undervolting mv from core, cache and gpumy battery now lasts about hours!!! The safest value I could undervolt it without crashing the system was mv on all 3 options on Linux. So, what does sqlite manager old version means: first, I don't need to run this note at 4Ghz fulltime!
So, undervolting not only made battery lasts longer but also made the whole experience more pleasant. It would be great if Dell could make a bios upgrade that did this undervolting in a more definitive way. Intel doesn't allow vendors to do this, but gives XTU to users. ThrottleStop is another alternative. The CPU may go to but your hands shouldn't burn though your CPU load may not be so heavy, try Prime95 for a couple 9xmovies city minutes to see if your paste is okay.
Try locating a charging circuit near left shift position, next to a metallic shielding plate inside, and pad it to the backplate. Have you padded the VRMs? It needs half a kg more in heatpipes and fins to run properly. The original VRAM pads don't need to be replaced, perhaps add pieces of 0. Some folks even got worse results after repasting with pad replacement, because they used too thick pads, so the gap between the chip dye and the heatsink was not as thin as possible.
VRM mosfets need some pads badly, or perhaps even something more elaborate if you've got time, look up iunlock's mod. Browse Community. Turn on suggestions.

Phacjkwer 2 Bronze. XPS 15i9 overheating, solved with undervolting technique. Hi all. Here is a printscreen showing machine details and the battery life using powertop to check it.
All forum topics Previous Topic Next Topic. LuciousDK 1 Copper.Have you ever looked for why Undervolting and underclocking the GPU is the best thing you can do? You are in the right place because we have an answer to your question, go through the article, and find the answer. Before knowing the importance of underclocking and Undervolting your GPUyou need to understand that what underclocking and Undervolting are? As overvolting increases the power consumption in a CPU.
Undervolting is the opposite of overvolting; it can decrease the power consumption of your CPU.
Basically to decrease the voltage of computer processors and components dynamically on the run time is called Undervolting. In this process, the dynamic voltage scaling conserves electrical voltage to reduce energy consumption and also to minimize the heat production of computing components.
Undervolting implemented in devices that have limited electrical supply and are powered by a battery, such as laptops and mobile devices. Typically, Undervolting can manage by using any software-based power management utilities. But sometimes in most of the operating systemsuch utilities are already available by default.
I know the first question which clicks in your mind after reading the definition Undervolting must be that does Undervolting GPU reduce performance? As we all know, thermal throttling is dangerous for your PC; even Undervolting will help you to avoid thermal throttling. Undervolting your GPU also allows your system not heating up as much, which means the fans will not have to work as hard.
It will keep maintaining the temperature of your system. Undervolting GPU is pretty much beneficial for the devices running on batteries, especially for laptops. For an excellent gaming experience, the essential thing which you have to do is to keep your system fresh. That will help you to play intensive games smoothly without any interruption.
As we know, Undervolting means to maintain the voltages provided to your PC to reduce the temperature and heat produced by computer components. Now you can understand that Undervolting contributes to improving your gaming experience.
I hope you have also found the answer to your question, does Undervolting increase FPS? There are lots of ways to Undervolt GPU.
Go for your favorite one. But before starting one thing keep in your head that Undervolting your GPU beyond the specifications of manufacture may lead your system damage. The very first thing that you have to do is to enable the core voltage monitoring. A new core voltage monitor will appear showing system voltage in the system monitoring section. Now close the system monitor configuration window. Now take a screenshot from the snipping tool or note down the default core voltage.
In my opinion reduce voltage in increments of 0. If your system is still stable after making changes in voltage, it means that you have successfully Undervolt the GPU. Here is another method that you can follow to Undervolt your GPU.

This tool may damage your hardware since it uses reverse engineered methods of MSR usage. Use it on your own risk. For example, you can write undervolt 2 'CPU Cache' For example, power package 35 You can also specify a time window for each limit in seconds.
This value is subtracted from max temperature level. For example, tjoffset Energy versus performance preference is a hint for hardware-managed P-states HWP which is used for performance scaling. For instance, with performance hint my iU is able to run at 4. This feature is available in daemon mode only which will be described below. To get a better battery life, clock speed can be reduced until CPU is under continuous high load, which will hold the lowest CPU speed most of the time.
Hint switching can be configured depending on the CPU load: hwphint switch load:single Multiple hwphint switch rules can be used, the hint will be selected depending on current hint, which can be configured by another tool e. You can use hwphint force rule to set the hint independently, but only one rule can be declared in this case.
Run intel-undervolt read to read current values and intel-undervolt apply to apply configured values. You can apply your configuration automatically enabling intel-undervolt service. Elogind users should pass yes to enable option in intel-undervolt. Run intel-undervolt measure to display power consumption in interactive mode. This behavior can be suppressed applying limits periodically. Some features like energy vesus performance preference switch work in daemon mode only.I'm currently following your guide to undervolt my GPU and i'm at the last step where you mentioned the solution if my clock speed went down in my case, it went down from MHZ to MHZ after undervolt that i should use next higher speed afterbut i dont understand what you mean by that.
[GUIDE] How to undervolt your GPU - WINDOWS ONLY
Please help me! Hello I found your guide to be helpful and I think there is easier way to flatten the curve. I just want to share this because I found it extremely helpful since it could prevent me from wasting time on moving those little nodes on pin point accuracy. Hey mine was stable at 0. C and mhz. Can you explain it to me clearly how can I undervolt it more? Your laptop cooling system is having issues Decrease voltage with the same clock speed or, increase clock speed at the same voltage.
Which GPU you're using? My gpu is gtx btw. What laptop you're using? My laptop is asus xzd and unfortunately, It has only 1 fan but I do have fan cooler on it. Sadly, ryzen master doesn't support my processor, for thermal paste my unit is like only 3 months old and I dont really use it that much, should I replace the thermal paste already? GPU undervolting doesn't seem right, refer to the guide for correct steps Thermal paste used in most laptops is mostly bad.
Nice guide. I have a asus zephyrus s gx with iH and rtx Asus has its own boost mode which increases gpu core and memory and max fan speed. Can you use afterburner to increase fan speed? How would you start to make the tune in this situation? Would it be beneficial? If I'm not mistaken, you can enable max fan and customize fan speed under balanced mode also via Asus Armory Crate software correct me if I'm wrong.
Personally I will suggest using balanced mode, however since I don't have much experience using Asus gaming laptops, I might be wrong. The author of the article has a question for you. What temperature do you think is optimal for a laptop video card in my case it was warming up to 93 after undervolting became 80 does it make sense to go lower to lower frequencies to a certain temperature? And one more small question, you do not know how to make an undervolt on mobile processors Ryzen.
In my case, with the index "U". Depends on the GPU. Would advise doing repaste and lift the laptop for more airflow don't block intake vents Ryzen mobile CPUs don't support undervolting yet. I've mentioned this in the notes.However, given the colossal assembly line at which these processors roll out, some processor models are tested at voltages higher than they really need.
You save power when the CPU consumes less of it. This also leads to your system not heating up as much meaning the fans will no have to work as hard. Disclaimer: This process is straight forward and considered safe, but if you end up configuring the wrong thing, you could damage your PC. So do this exclusively at your own risk. Note: This is laptop exclusive because extending battery life is not a concern for desktops.
Even though the core methodology works for both PC and Android mobile, we will cover only PC, as Android needs to be rooted for this process.
Lastly, this process requires patience, because there is a lot of testing involved. Overclocking requires that we modify hardware to perform at greater levels than it was tested at. So, if you could make your CPU perform at the factory configuration by consuming less electricity, you will increase your battery life in two phases.
Phase 1 is the actual electricity you save in operating the processor and phase 2 is the power you save when your fan does not have to turn on as frequently. This, in turn, can extend the life of the system as well. Here is how you can safely undervolt your CPU. To undervolt your CPU, your laptop should be fully charged before you get started.
It is a simple tool that this will serve our introductory purposes today. Make sure you take a system backup. In the off chance things do go South, you will need a backup in case restoration is needed. Upon launching XTU, you will be greeted with a splash screen with all the action items in a menu on the left. This will be very useful when you start tinkering with the voltage.
Throttlestop undervolting doesn't seem to be working
Additionally, run some stress tests on your system as well. Ideally you should let it run for at least 30 minutes. In this time your CPU will get hot and your fans will start running at full capacity. Once the test is complete you will have a very good reference to how your CPU normally behaves.
If your values are at default, they will all be in blue. Y ou will see a list of voltages at 0. What you want to do is click on this voltage and scroll up to when you start seeing negative voltages. If we go in the positive, we are sending more volts to the processor, risking damage.
Negative is where we are safe. If you decrease this gradually 0. The best indicator will be a blue screen of death. If you have undervolted it too much, the system will crash under heavy stress. Upon crashing, you should restart the system and revert the voltage to the last setting you successfully tested it on. Now, keep doing this with successive 0.
Once you find the exact voltage that does not make your CPU crash for 30 minutes of stress testing. You should conduct one more stress test.Trying to lower temperatures, improve performance, or increase battery life is all about making small tweaks that can add up to something more noticeable. This guide covers the layout of Intel XTU and gives the process for adjusting voltage and TDP to reduce temperatures, extend battery life, and improve performance.
Many enthusiasts prefer to handle this via BIOS, but Intel XTU provides options for modifying metrics such as core voltage, clock speed multiplier on supported CPUsand turbo boost power limits if the manufacturer has enabled this option.
Intel XTU functions similarly to the third-party ThrottleStop utility, a fan favorite in the mobile computing community. The two programs modify many of the same registers and it can get a bit messy. When you first open Intel XTU, you are greeted by a screen which shows detailed information about your hardware, such as the processor, memory, motherboard and so on.
This data can be useful for people who are trying to help with troubleshooting via a forum but remember to hide any serial numbers. On the left-hand side is the navigation menu where you will flick through the various functions needed for undervolting or overclocking. Along the bottom, you will see a line graph and a table showing output data from the hardware and associated sensors inside your notebook. Best Displaysfor University Students. Instead, we will adjust the offset, which allows the processor to dynamically change the voltage to match the task, i.
This offset works by taking the level that the CPU would have adjusted to and then increasing or decreasing it by the level of the offset. The turbo boost power max setting controls how many watts the chipset including GPU can draw, and several manufacturers lock this setting. You can set a custom length for the stress test to run for, and each test tries to create a full load without creating the workload saturation that the two previously mentioned stress tests cause.
The inbuilt tests are useful for assessing stability during the undervolting or overclocking process, while Prime95 or AIDA64 can be used to validate stability once you have finished tweaking your 'long-term' setting.
It is worth running the benchmark prior to tweaking any settings since it can be used as a reference point to assess any gains we achieve.
It is our experience that if you see a noticeable difference in benchmark score within Intel XTU, then your system is throttling in a comparatively short period. The most common result we achieve is for the 'before' and 'after' benchmark scores to be within a few points of each other when undervolting. To be fair to Intel, this utility is their recommended software i.
To improve readability, we suggest changing the displayed time period to something lower than 10 minutes using the drop down in the bottom right. Intel XTU lets you create multiple profiles of various tweaks which you can switch between quickly. However, if you have a CPU capable of overclocking, then you may create an overclocked profile for tasks such as gaming or video editing, and an undervolted profile which you run during regular computing for improved thermals and battery life.
