Hi everyone, I'm sure you guys get alot of these but I am still new here. Last night I tried to overclock my gtx 770 and i raised up the memory and the clock a bit too high and on my screen it turned pink and nothing was working. The display just went crazy and the driver crashed I tried 3 times but i shut my pc off each time it started going crazy and everything reset to default on the card. Right now im using EVGA precision and i'm just using fps target to do it for me. Everything is on default right now and i am scared to touch the memory and boost clock again. I'm really paranoid even though i didn't run a game or use the pc while everything was pink, i'm scared i did damage. Did i damage my GPU? It works just fine it hasn't crashed and i don't see any pink dots or anything. What did all of those pink dots and the display looking all messed up mean? I'm really scared I screwed up something.

You might have temporarily set it to high, and after the reset it went back to normal with no permanent damage.
Though I wouldn't do that again.

alrighty, thank you. yeah i won't touch those settings unless i know for sure i know what the hell i am doing, but man i got so scared that i really screwed something up.

That's the sign that you pushed the card too far and will likely not cause damage. Just don't tamper with the voltage unless you know what you're doing.

If you want to give it another shot, try increasing the memory clock 10-20MHz at a time and stressing for a few minutes each time until it crashes again. Then put it back to the last stable setting then do the same for the core clock but try slightly smaller bumps until it crashes. Then you'll have your max stable overclock!

You poked the bear, yet the bear didn't claw back.

Next time you're getting mauled.

Don't do it again.

If you feel the need to overclock a stock air cooled card, increase the base clock only, and leave the memory speed alone, because the greatest discrete GPU failures are from damaged memory chips.

One of the most disturbing findings I have run across is the improper installation of the heat sink on the card and it happens from every brand name out there.

Some have everything installed properly and some don't, meaning the thermal padding fully covering all the memory chips, and the voltage regulators on the card, plus the thermal compound on the GPU die or heat spreader properly applied.

These things are unknown until you pull the heat sink and see whats going on under the hood, that's why I personally never overclock a GPU until I know what's under the hood has been properly done.

Am I suggesting you remove your heat sink and inspect underneath?

Not unless you know what you are doing, and not unless you have replacement thermal padding, because it is not supposed to be reused as it seats in with heat, and all cards generally use 2 different thicknesses of thermal padding, one thickness for the memory chips and a thicker for the voltage regulators.

Additionally some good thermal compound on hand for the GPU itself.

Pink dots is artifacting, and artifacting is bad, you can stumble into a situation like this and walk away after it's all reset to default with no card damage, or you can continue overclocking the memory and seriously cripple your card.

Artifacting is a warning, your memory chips have no temperature monitoring so you cannot go by your GPU temperature reading and think you're safe, if one of your thermal pads is only partially covering the memory chip it's not being properly cooled.

All hardware is different even when everything is properly covered, just because Joe can reach certain overclock ###s, does not mean you can as well, there are no guarantees when it comes to overclocking.
