Hi all,

Yesterday I've built a new rig. Everything worked fine except my gpu crashed everythime i started a game. I had to shut down the process trough taskmanager and got the message "display driver does not respond and has been succesfully recovered."
I tried everything to fix it and eventually I went playing with the GPU voltage.
Increasing the voltage didn't help a bit but decreasing it made it stable somehow!

I have a MSI R6870-2PM2D1GD5/OC GPU and decreased the voltage from the standard 1.2V to 1.1V.
I'm glad to know my gpu is not broken but I find it weird that a decreasement made it stable instead of increasement.

I would like to ask if there are any consequences I might find with this action. Is it safe? Does it make my gpu have a shorter lifespan or does it make it a bit slower maybe?

I'm eager to get a reply to this
 
if it works, it wouldn't hurt it. What i think may be happening: video cards now have an Idle speed and voltage, and a Load speed and voltage. I suspect there is something wrong with your card and its not bumping up the voltage under load, so by you forcing a voltage, although not as high as recommended, it may be enough to get it stable under load. you can monitor this with msi afterburner to see if this is what is happening.
 

Decreasng the voltage will not decrease the lifespan of the card. If anything, it will run a little bit cooler. And if you did not do anything to decrease the GPU clocks, it will not run slower.
