Graphic Card Undervolting
Is Graphic Card Undervolting safe ? Simple answer Yes Underclocking is definitely safer for your graphics card. it's simply telling your gpu not to work at his full. This should in no way damage it. If anything, underclocking your GPU may actually extend the life of your graphics card. Undervoltage alone will not reduce GPU performance, but it may reduce stability. You may experience graphics artifacts, BSODs, or boot failures. Games are becoming more heavy as they integrate new technologies. Comparing any game to a game from decades ago, you can see significant differences in the stats by your PC during benchmarking. Of course, modern games consume more CPU and GPU power than older games. This is because rendering highly rendered textures, photorealistic environments, and detailed shadows requires a lot of power, all of this load comes on the GPU. In this case, lowering the GPU voltage is recommended if you want consistent, uninterrupted gaming with overall acceptable temperatures. Underclocking reduces the maximum potential performance of your GPU, but allows it to remain stable at lower voltages. 

But Why would you want to run less voltage to the gpu it doesn't even make sense in our constant battle to get more fps out of our hardware, there's one often overlooked way we can do that it's called undervolting, it's the process of running less core voltage to the gpu to increase its performance now this seems a little counterproductive because typically to get a better overclock you would want to use more voltage unfortunately modern gpus lock the maximum voltage to the core without doing a voltage mod or flashing a modified bios you're stuck with a maximum core voltage that's set in the bios however you're not limited to how low you can set the core voltage so why would you want to lower the core voltage, well that's a great question when it comes down to how gpu boost works getting the best performance possible out of your gpu doesn't always mean the highest possible clock speeds but rather the most consistent clock speeds gpu boost works by setting the maximum boost of the gpu based on a few factors these factors are temperature and power limit the gpu will boost until it hits its power limit and it will maintain this boost as long as the temperature stays under a specific value curve as the temperature rises the gpu will lower its maximum boost speed by under volting we're able to lower the gpu's temperature and in turn allow the gpu to maintain its maximum boost speed for longer. Lower your gpu power consumption will make lower gpu temperature. You’ll also enjoy a lower electricity bill, even if it’s just by a smidge. This lower heat can also mean improve thermal performance for your other pc surrounding components, such as the CPU. With modern GPUs using more and more power, this can be necessary in mitigating the consequences on your PC eco system. Your power supply will be less stressed too and its safe these undervolt never do any damage to your gpu. Apart from this, you also get less noise from fans that is another good advantage of undervolting of your graphic card, because when your graphic card runs on stock voltage and when temperature get high your graphic card fans start to run on their full speed which increase fan noise and sometimes this loud fan noise ruin your gaming experience so if you are getting high fan noise from your graphic card you shoud undervolt your gpu.

Let's give you a example of undervolt if our stock boost clock is 1.9 gigahertz but we can get a stable overclock at 2 gigahertz but the gpu can only maintain that for a short period of time and then drop down to 1.8 gigahertz we could actually get better overall performance if we could lower the temperature so the gpu could maintain 1.9 consistently even though we're not maintaining our highest possible boost clock we are maintaining a higher boost clock for a longer period of time at least that's the idea now the reason we're able to do this comes down to the silicone lottery manufacturers will set the default voltage curve based on the most reliable settings across all different variations within the silicone of a specifically bin gpu for instance the Rtx 3060 has a maximum core voltage of 1081 millivolts and a factory boost clock of 1935. We already know that 3060 will run a stable overclock at 21.15. we can actually go higher but it starts to get a little flaky in some games so we typically keep it around 21.15 however when you're running at those speeds on the core you're obviously going to create more heat as the temperatures rise the gpu will down clock to maintain temperatures so my 2115 wouldn't be consistent without doing something about the temperature the way you solved this problem is by simply water cooling the gpu at the absolute highest overclock our 3060 never goes over 58c in fact typically it stays around 55 c because we are able to maintain 2.1 gigahertz almost indefinitely however when this card was air-cooled it regularly fell below 1.8, if you don't want to spend a ton of money water cooling your system you can undervolt it for free and get similar results at least with factory clock speeds. 

You can use MSI Afterburner to undervolt your gpu if you don't know what undervolt settings is best for your gpu you can search on internet for your card best undervolt settings and apply those but keep this in mind when you undervolt your GPU, your GPU temperature will drop dramatically and it won't loose sweat while running your games. However, you should still monitor performance. Be aware that after that, some programs will start lagging and some programs will quit unexpectedly. In such cases, just reset the settings. If your GPU is new and expensive, it can be difficult to decide whether to go for a lower voltage to undervolt. It's definitely safe to undervolt the GPU, but it can be a daunting experience for newbies who lack the knowledge or experience of messing around with GPUs but these is no need to worry you can see stable undervolt setting for your gpu on internet.
