I have a pre overclocked evga 780 that works great with its factory overclock but when I overclock it a little more it will crash but only when I am playing a game. All of my stress testing programs (furmark heaven and valley) pass with flying colors but its always a no go when I play any game. The game will just freeze and not recover except for one or two instances in batman arkham asylum. I just want some advice as to why this is happening?

It's probably at it's limits for OCing. This is likely to be at a low boost in clock speed because it is factory OC'ed already. Not every bench/stress will crash an unstable GPU/CPU/RAM, but it is strange that there aren't any of those three programs inducing a crash.

The rest of your specs including power supply make and model?

You will probably get game crashes after overclocking if your PSU isn't powerful enough to handle the overclock, or you've pushed your card too hard. Actual video games tend to be more intense than the test programs :p

Actually that's not true at all. One of the few things AMD and Nvidia agree on is that Furmark is basically a heat causing virus. No game will push a card as hard as Furmark either with heat or voltage.

Also his card is factory overclocked. It's warrantied at the speed it shipped with. And EVGA warranties overclocking anyway.

It certainly could be a substandard power supply though.

Yeah I know, but what I meant was the game will go on for longer. Most of the time you won't run tests for hours, but with video games you play for a while. :p

True. And I have seen both cards and CPUs that pass stress tests with flying colors and fail in general day to day use. But in general a stress test will push harder than any game will ;)

Well my PC specs are
CPU-amd 8150 oc to 4.5 ghz
Mobo-Gigabyte 970a-ud3
PSU-seasonic 750 watt 90+ gold
Ram-gskill ripjaw 1600mhz

oh yea and the memory on my card must be great I got it to overclock to 1900mhz no problem in game stable its just the core clock that is being stupid. The only reason I am overclocking is because metro last light dips into the low 20's and that bothers me especially in a shooter.

Cool. I wouldn't recommend overclocking anything to the max though, because sometimes the heat can kill the card :p 

Best solution

Well you have one of the best power supplies on the market so that's not the issue. Back off the overclock a bit until it's stable.

Yea I just guess even the 780 can't handle metro as full settings lol
