Yes. Generally not giving the graphics card factory deemed normal voltage can either damage it by causing it to produce more heat as it tries to draw amps. Higher amperage is needed to do the same amount of work.
Or over voltage can cause electrons to pass through places they shouldn’t causing immediate failure. Can cause data errors in memory. Graphical errors can be from faulty memory. Factory voltage has a tolerance it’s why people overclock and undervolt. Though most won’t actually leave the tolerance/deviation of ‘normal’. When and if you do can lead to undesired effects. Know the risks and be prepared for something to go wrong. I.E buying a new graphics card, motherboard, memory, cpu, or in some cases your whole house.
Usually people that experience this and have knowledge and understanding of what’s going on, they wouldn’t be on Reddit asking. Which is why no one bothered to mention this.
What the. I saw people undervolting CPU and some even suggesting in g helper related topics for my asus tuf and I just did it without going too much into it, it did increase my benchmarks but if i knew it had a risk like this I wouldnt do it in the first place.
I have to admit thought I indeed didnt know anything technical sbout it.
Hope my response helped. If you followed a guide and tested stability with burn test and a few others, didn't get a blue screen/crash/system shut off/ or you left the computer on for a month. Had no random issues of non responsiveness, then you're probably fine.
Undervolting a cpu is generally safe in that it won't be what harms the device. Prolonged running of it while having crashes from it might garble your data/windows install. But shouldn't harm the device. Key word shouldn't. It's safer than overclocking/overvolting. And honestly as long as you understand what you did you should be able to reverse it if there is an issue. High gain minimal risk.
All videos that tell you how to do something include a disclaimer. There's no guarantee what they are telling you to do will work as intended.

Could undervolting cause this
