GPU cooked?

[Crystallight]

Hello my screen went both off while gaming I think my gpu overheated I quickly turned my pc off and took my gpu out.

I took my gpu apart and re-added some new thermal paste to it and re-seated my gpu.

Is it safe to turn it back on again?

Thats quite extreme! You didnt try to check the temperatures?   Yes, try to turn the PC on again.

No wasn't checking I'm quite worried what going to happen. Shaking a little from it.

well "if" there is any damage, it is already done, can't see any harm in booting it up. i see no reason(based on what you've said) to think something catastrophic happened, crashes do occasionally happen. boot it up and check your temps, and play a game or run a benchmark while checking temps.

PC started up fine I knew overvoltage was not a smart idea I thought it could handle it though new thermal paste seem to of helped it sound less like a jet engine.

What program did you use to ''overvolt'' it?

Does any GPU actually get a performance boost from overvolting?

 

I think if anything it would actually make it run slower because you will bounce of the power limit with a lower clock speed.

 

If you want to overclock your GPU you need to raise the maximum boost clock whilst undervolting.

 

Overvolting hasnt really been a thing for quite a few generations.

 

you are trying to run the lowest stable voltage you because a modern gpu has a dynamic voltage curve , all you are doing is creating an offset to run any giving clock speed at a lower voltage which is a good thing for achieving high clock speeds.

 

Anyways its extremely unlikely there's any damage done , What's happend is that you've had a hard GPU crash.

 

It's really not a big deal and shouldn't have caused you to go running for thermal paste the second it happend.

 

I had many of them trying to get a stable undervolt , most just crashed to desktop but a few times I completely lost the GPU connection and had to hard reset.

 

Also what GPU is it?
