What is undervolting
In order for a video card chip to work properly, it must be supplied with a current of a certain voltage. The manufacturer lays a small margin up and down, so with the help of special programs you can both increase and decrease the voltage.
Raise it to increase the power of the video card. And if you lower the voltage, you can achieve the same performance and significantly reduce power consumption and heating. As a result, the video card will work as before, but it will make less noise and heat up. This is undervolting.
Unlike overvoltage, which can cause overheating and damage the device, undervoltage does not harm the graphics card. The maximum that can happen is that a decrease in performance will lead to less stable operation of games and programs. But all these problems can be solved by returning the voltage to its previous levels.

Is the card even capable of going below that?
no. usually gpus under 1000mv will become unstable. mine is unstable under 1100mv
QUOTE ME FOR ANSWER.
Tier lists for building a PC.
Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.
(Also case airflow matter or if you are using Downcraft air cooler)
GPU tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for water cooling. Tier A and B for overclocking. Tier C stock and Tier D avoid.
( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)
Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.
(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

(With a grain of salt, I use tier C for OS myself)
Case Tier List. Work In Progress. Most Phanteks airflow series cases already done!
Ask me anything
And read the materiel? 78 degrees is a normal temperature. High — 85 and above.
Why? This is her normal temperature, look for the specification for the card, all the allowable temperatures are listed there.
This is normal for the 3070ti. My 3070 gets so warm in the last plug tail, but for a plug tail it’s normal.
Chilit I have 1080 Ti with 52-55 in winter and 55-58 in summer)) 825mV
I have 1660s under load up to 76-77. And here a hotter card produces the same numbers. You should not bother.
If it works, then don’t
In theory, you can make an undervolt, but if you have never touched this, it’s better not to interfere so as not to screw up the video.
And so I have 3060ti up to 80 sometimes it heats up on hotspot
Can’t, Nvidia has foolproof software everywhere. Is that physically able to kill.
I tried to do it, it started with the fact that I couldn’t even set up MSI, he didn’t see the voltage and refused to show the window.
It turned out that there is a checkmark to click on, related to AMD video cards.
And then I realized that the fuck should be better to sit with a warm video.
Then it’s really better not to touch)))
Well, it’s not worth updating the computer at all. Suddenly short something during disassembly/assembly
And I don’t collect it myself, fuck it.
There is a proven person who, for a small share, will do everything in the best possible way.
that is, you don’t assemble PC yourself, pissing at least touch it with your finger and spreading advice on PC to people? base dtf
In any case, the same downvolt, GPU / memory chip overclocking and power limit setting in AMD drivers have long been one of the main functions.
Any current hardware, with 10 minutes to spare, can be made a little faster / a little more energy efficient without losing anything.
I have a 3060ti. I made an undervolt — the performance did not fall, but the temperatures are now up to 60 degrees. Lower temperature means longer life.
Cool, in my case, I even found a window with voltage only after an hour of picking MSI.
I don’t know, I watched a couple of videos and did everything for 30-40 minutes. Most of the time was spent on runs in stress tests. I have been using M SI Afterburner all my life, maybe that’s why it was easy to navigate. Just after my red vidyaha burned out at «safe ~ 80 degrees» I decided that I shouldn’t heat them like that)
Also when it was 3060, Tee did a downvolt from the fires, because the Dual version rattled the fans too loudly for my taste
IMHO this is worth doing if you are not satisfied with the noise of the fans and there is a desire to reduce it. Because of the temperature of 78 degrees, there is no point in worrying. It happens that some games are unstable due to undervolting / overclocking, this should also be kept in mind.
The temperature is normal, but the undervolt will only benefit her. I don’t remember the details for sure, but with a rather gentle undervolt, power consumption dropped by 20-30 watts.
Undervolt — theme. There are a lot of guides on the Internet for almost all kinds of GPU models from any vendors lol. To reduce the temperature / noise, you don’t even need to remove a lot of millivolts, nothing will happen to the chip. Often, when undervolting, the chip is overclocked at the same time
I made a 0.950v curve in the afterburner on the 3070ti — I ate less, warmed up less, the frequencies were the same.
My Boat Pointed Up
Tested Palit’s 3070 game rock for several days. Warmed in stock to 69 (70 for a short time at the peak). Good heat tests for modern nvidia cards are games with heavy ray tracing (Quake2 RTX, Portal RTX). Undervolt makes sense.
Well, this is not quite the right comparison. The temperatures at which notebook hardware can operate stably cannot be applied to a desktop PC. 🤷🏻♂️ For a vidyuhi in a computer, 80 degrees may already be a high threshold, when for a laptop vidyuhi it is at full operating temperature.
Okay so I’ve been reading that undervolting the 30 series cards, particularly the Ti cards is pretty much a ‘must do’ to improve the efficiency and temperature of the GPU without affecting performance too much, in some cases not at all.
I haven’t been having any issues with temps or stability using stock settings but I thought I’d see how I went with undervolting.
Here is a typical Heaven result at stock settings.
GPU = MSI Ventus 3x RTX 3070 Ti STOCK
Max Voltage = 1.055v
Max power draw = 289W
Max Core = 1965mhz
Heaven Score = 2898
Avg FPS = 111.5
Max temp = 76c
Max fan % — 68%
GPU = MSI Ventus 3x RTX 3070 Ti UNDERVOLTED
Max Voltage = 0.850v
Max power draw = 203.9W
Core = 1890mhz
Heaven Score = 2733
Avg FPS = 107.6
Max temp = 67c
Max fan % — 46%
Heaven was run at 1440p, windowed with all settings maxed, DX11. Afterburner and HW Info were also running
What do you think? Should I call it a day or could I improve further?

i think thats really good, try testing on warzone and or halo infinite as those games crash very easily if gpu oc/undervolt is unstable

I will definitely try some extended gaming sessions. Thanks
Runs very nicely, stable and relatively cool at 925mv, 1890mhz boost clock and 9801mhz on the memory (a +300 OC)
Would a similar profile work for a TUF 3070TI card?

Hi. I have a Zotac 3070 Ti Trinity OC that I snagged for 755$ converted here in the Philippines. First thing i did was play a match of COD Warzone and noted all stock fps, clocks, power draw, thermals, fan noise.
Anyway, thermals have improved, power draw significantly decreased to around 160-190watts with an occasional max peak to 210watts.
Here’s my Heaven benchmark result:

The most popular and understandable program for overclocking and undervolting video cards is . Here’s what you need to do to lower the voltage with it.
Unlock voltage control. By default, MSI Afterburner has voltage control disabled. This is done so that inexperienced users do not apply excessive voltage to the video card, from which it can fail.
To unlock the voltage control, you need to click on the gear in the program interface.
MSI Afterburner interface. Settings are opened by clicking on the gear icon
After pressing the button, a menu will open, in which you need to check the box «Unlock voltage control». To carry out monitoring within the program, it is worth at the same time checking the «Unlock voltage monitoring» parameter.
Settings required for voltage control
Sometimes it is not possible to unlock the voltage control with the button. In this case, you need to change one of the program’s configuration files. To do this, open the folder where you installed MSI Afterburner and go to the Profiles folder. Find the settings file in the folder, it starts with VEN_, open it with Notepad and add two lines to the end:
Example of finished configuration file
Save the file after changes and reload the program — voltage control will become available.
Change the voltage readings. You can lower the voltage in the CORE VOLTAGE column — initially, the current indicator of the video card is affixed to it. To change it, just enter a new value in the column.
You need to change the numbers in the CORE VOLTAGE column
Lower the voltage gradually: changes are reflected differently on video cards, so it is impossible to derive a universal indicator. For the first step, you can lower the voltage by 50 millivolts, then — 1% per step.
For example, the Radeon RX 560 has a default voltage of 1043 millivolts. For the first step, it is worth subtracting 50 millivolts — the new value will be 993. Then — 1% per step: subtract 9.93 from 993, 9.83 from 983 and beyond. Values can be rounded for ease of calculation.
After making changes, don’t forget to save them, click on the button with the floppy disk at the bottom
Repeat the steps until you are satisfied with the result. You can track the results of changes at intermediate stages using monitoring inside MSI Afterburner. It is launched with a button that depicts a computer with a graph.
Clicking on the computer icon opens the monitoring mode
After pressing the button, monitoring will open, which displays the heating of the video card. In order not to conduct stress tests after each change, you can rely on this data: they are less accurate, but they allow you to monitor the process right while using the computer.
Try to observe different indicators. For example, if the processor temperature starts to rise significantly under load, you should think about improving the cooling in the case
When finished changing the settings, perform a test. Run FurMark on the same preset as the pretest. The program will load the computer, record the indicators and issue a report.
Then compare the results before and after undervolting: if the maximum temperature has decreased and the SCORE parameter has not changed significantly for the worse, the undervolting was successful.

When it can help
Undervolting is worth considering if your video card constantly heats up above 80 degrees under load, and its fans are noisy all the time. This can happen for many reasons, including when the computer gets dirty with dust or when the cooling system fails. Therefore, before undervolting, check the following:
If the heatsinks are clean and there are enough fans, but the video card still overheats, undervolting can be a lifesaver and significantly lower operating temperatures — by 5-10 degrees, sometimes more.
How to prepare for undervolting
Check the baseline of the graphics card first with stress tests. For example, run the program — it is well suited for checking the video card for noise and heating. Install it and run one of the four test presets, depending on what resolution your monitor has.
FurMark interface
A test will begin, during which the video card will warm up and the fans will start to run at maximum speed. There will be a chip temperature curve in the lower left corner of the test, pay attention to it.
Temperature curve. Pay attention to both the heating rate and the maximum number
After the test is completed, the program will issue a report in which you need to pay attention to the maximum temperature and the number of points in the SCORE line, which indicates the performance of the device.
Baseline temperature and SCORE — the reference point for assessing the effect
The main task of undervolting is to reduce the temperature of the video card as much as possible, but not to lose performance. Memorize the resulting numbers and proceed.
How to lower the voltage of the video card
Check computer cooling. Verify that the chassis fans are working properly. There should be at least two for blowing in and one for blowing out.
Clean the heatsinks of the video card. If they are clogged with dust, this may increase the temperature of the component.
Do preliminary tests. Record graphics card heat and performance metrics with graphics card stress tests. For this, the FurMark program is suitable.
Change the voltage on the graphics core. You can use MSI Afterburner for this. Reduce the indicators gradually until you achieve the desired result.
To do this, repeat the stress test of the video card and compare the reports before and after. The ideal result is if the temperature has decreased, but the performance has not decreased.
