Regarding AMD, the grass is rarely greener on the other side. Finally, there is App->Profile pairing. Can i revert this change (bios downgrade doesn't seems to help - tried to 1.9.0 v)? Just a simple stress test using Intel XTU with Auto and Max Fan. The Core-Voltage section is greyed out. It was running smoothly for a month until yesterday, when I read online about XTU, the Intel tool to change CPU voltage and else. It is time to test stability under load using the built-in CPU stress test. The Best Smartphones for Less Than 160 Euros. Since we want to save time we are going to pick a start point based on our experience, and the experience of others online, where we know it should be safe to start with an offset of -0.050 (50 mV) on our Kaby Lake i5-7200u. If your system hasn’t frozen then it has passed the first step — it is stable at idle. If your laptop isn’t very overclocking friendly (ie not easy to recover from bad BIOS settings), it’s probably not very undervolting-friendly either. 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. Intel XTU functions similarly to the third-party ThrottleStop utility, a fan favorite in the mobile computing community. While XTU shares some of the responsibility, as does Intel, so does the user. I did this after I reverted back to 1.5 but I'm not sure It had to be done in that version. Other areas include the ability to undervolt the integrated Intel HD GPU to free up some of the power limit for the CPU cores in power-limit-based throttling. 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 CPUs), and turbo boost power limits (if the manufacturer has enabled this option).However, most of us own laptops that aren’t capable of overclocking, both because of the change Intel processors underwent when moving from a traditional FSB to a BCLK setup several years ago, and because our cooling systems aren’t able to handle that thermal output. Once you are happy with the undervolt achieved, hit the save button on the right side and give it a descriptive name. I agree that the only solution now is to prevent undervolting. The two programs modify many of the same registers and it can get a bit messy. No more software voltage control after this fix is installed. The reason for this is we want to quickly find the point where it is unstable under any load whatsoever, and 10 minutes is long enough to show this. And now, AMD had joined to laptop market. For our testing, we’re only going to set it to run for 10 minutes during these early stages. Hey guys! I use xtu because it’s more simple to handle troubleshooting by overclocking on eGPU setting, without egpu setting I would use throttlestop. We suggest looking up your processor model on the Intel ARK database to confirm the TDP specification (use the search).Some manufacturers will modify the TDP allowance to be higher (performance) or lower (quietness) than the stock value prior to the laptop leaving the factory. Intel, and manufacturers, might already be better tuning the voltage from factory. For most readers, this feature won’t get much use, because once you have found the best stable undervolt your system can handle, you will run like that for months at a time. Undervolting has been my go to tool on Dell XPS 15 9560 with 7700hq to keep the temperatures under control. 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.e., non-BIOS) method of overclocking K-series processors, so this benchmark is designed to measure the performance gain from increasing clock speed.So while this benchmark can help indicate a CPU that was severely throttling, we’re most interested in the highest CPU temperature that it reports. After installing new bios update, i can't undervolting my laptop anymore (intel xtu/throttle stop) due to new intel microcode (plunder volt vulnerability). Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Doc . Then monitor temperatures — or the thermal throttle flag — using the graph function in Intel XTU which continually monitors while the software is open.If you’re performing this on a gaming laptop, then running a synthetic graphics benchmark during testing will help to imitate the dual CPU/GPU loads experienced during gaming. I haven't updated my BIOS if you're wondering. Intel® Extreme Tuning Utility (Intel® XTU) is aimed at intermediate-level users that have some basic knowledge about overclocking and how it works. XTU is a solution can be acceptable, undervolt CPU, undervolt iGPU, decrease Boost clock can help the temperature lower 5-10 degree. However, if that's not the case, try installing an older vsrsion of Intel XTU, and see if the problem persists. After this I started building my own computers, and tearing laptops apart, which gave me an insight into hardware and how it works in a complete system. Fortunately, some of the settings available to us — like the core voltage — aren’t just used for overclocking, they can also be used to reduce the thermal load on our systems.So to add to Intel’s description regarding overclocking, we’d say that Intel XTU is a tool that lets us adjust settings that can lower the temperatures that our system hits under load, potentially cause the fans to run quieter, and maybe even extend battery life. Now change to your starting offset using the arrow buttons or the dropdown list and hit apply. Instead, we will adjust the offset, which allows the processor to dynamically change the voltage to match the task, i.e., lower when idling and higher when working hard. After I updated to 1.6 again the undervolt option was enabled in Intel extreme tuning utility. Also the benchmarking portion does not work anymore and the monitoring part seems off (for example task manager reports 5% cpu usage, while XTU shows 30%, temperatures over tjunction without heavy throttling etc). The first step is to run the in-program benchmark to provide us a baseline to compare against. Along the bottom, you will see a line graph and a table showing output data from the hardware and associated sensors inside your notebook. Reply. I'm not sure what's the moral of this comment. The 4-core/8-thread Coffee Lake U-series is a particularly strong candidate for this treatment due to its low base clock speeds, but only in systems with a suitable cooling system (often a 15-inch notebook).Note: You risk damaging your computer over time if you exceed the thermal capacity of your cooling solution. A bad or accidental setting could keep your laptop from starting up in which case your laptop might be toast (unless pulling the main + cell battery works or you get lucky and some other BIOS reset option works). I tried using Intel XTU on my Predator Helios 300 (2019) (I5 9300H + RTX 2060) to undervolt the CPU. As a generalization, many Skylake Core U-series mobile processors seem to find their upper limit between -0.060 to -0.080 volts (-60 to -80 mV), while Kaby Lake U-series is more around -0.070 to -0.100 (-70 to -100 mV). Craig Ward, 2018-03- 9 (Update: 2018-03-10). Trying to lower temperatures, improve performance, or increase battery life is all about making small tweaks that can add up to something more noticeable. It was pretty decent but I found Throttlestop much more workable.

Later, we will refine our settings and run a more extensive stress test to test stability properly. If you don’t, we recommend that you check out our guide to overclocking before proceeding.. For this guide, we will be using an Intel® Core™ i9-9900K desktop processor, and our recommendations and results will reflect that. With this running cne20 its achieving 2900-3050pts. A CPU needs a particular voltage to switch on and to maintain normal operation over time. The impact that Intel XTU has on thermal throttling might not be immediately apparent since it might only be delaying the point that the throttling starts or reducing the amount that the CPU throttles. If you really want to be thorough about measuring temperatures, then switch to the ‘stress test’ tab and select a longer test time or load a heavier benchmark (e.g., Prime95, AIDA64). Przycisk save nic nie daje. However, XTU should never have been allowed to install on an unsupported processor in the first place. If your computer freezes at this stage and doesn’t restart automatically, then hold the power button to reset and boot back into Windows. Read what you want into the comment. The only two settings we’re concerned with today are ‘core voltage offset’ and ‘turbo boost power max.’ When overclocking desktop systems it is common to set a static voltage to improve stability, but on mobile devices this can lead to reduced battery life. The information displayed along the bottom of the screen is where most of the value is for undervolting. If you are using Intel XTU for undervolting you will need to match Core and Cache undervolt. 0 Kudos Share. When it comes to adjusting hardware settings, you start going down one path and then it branches out into multiple use cases and scenarios. If you really want to be thorough about measuring temperatures, then switch to the ‘stress test’ tab and select a longer test time or load a heavier benchmark (e.g., Prime95, AIDA64). The TDP is around 15 watts for the U-series processor family typically found in many ultrabooks but will be lower for Celeron, Pentium, and Y-series, or higher for HQ and HK processors. Good day. If your system hasn’t frozen then it has passed the first step — it is stable at idle. And Intel's Extreme Tuning Utility download link. I managed to get the undervolt option back when I did a "reset to default" in the BIOS. 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. It works by using a program or process to trigger Intel XTU to switch between pre-set profiles automatically, such as changing from the daily-use 'undervolt profile' to the 'overclocked profile' when it detects that a pre-selected game is launching. Because there is a level of variation in every chip, they are shipped from the factory with a safety margin in their default operating voltage. XTU has always listed what processors are supported. My CPU voltage control is greyed out and I can't undervolt or overclock my CPU. We’d like to mention that this thin-and-light notebook was the candidate of an earlier test to reduce hardware temperatures and lower fan noise by using thermal pads to form a connection between the heatsink and heat pipes with the metal bottom panel, it also had the factory thermal paste replaced at the same time. The reason for this is we want to quickly find the point where it is unstable under any load whatsoever, and 10 minutes is long enough to show this. I have an Alienware m15 with i9 8 950HK processor. In the late 90's and early 00's I started learning how to tinker with Windows, while also playing around with Linux distributions, both of which gave me an interest for learning how to make software do what you want it to do, and modifying settings that aren't normally user accessible. We will start adjusting the CPU core voltage offset, which moves in increments and decrements of 0.005 volts (5 mV) for each step up or down. I grew up in a family surrounded by technology, starting with my father loading up games for me on a Commodore 64, and later on a 486. I uninstalled Intel XTU but I noticed that when I boot up my laptop now - the default -0.125V undervolt the CPU comes with out of the box is gone. Some users have had BIOS updates with this microcode update forced onto their computers from Windows Update. Intel XTU is a Windows*-based performance-tuning software that enables novice and experienced enthusiasts to overclock, monitor, and stress a system. Those who run right on the knife's edge with undervolting or overclocking prefer to run software such as Prime95 or AIDA64 for half a day, but this is more than we need for our purpose. Achieving the same benchmark score while reaching a maximum temperature that is 5oC (~9oF) lower than before any settings were changed shows that the goal of making the laptop run cooler has been achieved.To improve readability, we suggest changing the displayed time period to something lower than 10 minutes using the drop down in the bottom right.
