Crysis 3 crashing (while overclocked)?

Haven't tested other games yet, but Crysis 3 crashes the GPU driver (sending me back to desktop) after about 30 seconds or so if I overclock the GPU. Even if it is a modest overclock to +135MHz on core or even less than that, it still crashes. Temps aren't the issue as the game doesn't have long enough to even allow temps to build up to problematic levels.

I'm not entirely sure what the issue is, I haven't modified the voltage or power limits at all. So only clock changes.

Just wondering if you guys have any idea what the cause could be? Is it simply that Crysis 3 is too demanding to allow for a GPU overclock?

 

Your GPU just isn't stable at that clock then. Either raise the voltage or lower your OC.

 

Test some other games and see if crashing occurs. Also reduce OC until point when crashing stops and tell us on what clocks is card stable...

 

Crysis is very very tough on the GPU, so my money is on the overclock not being stable.

 

I'd agree, it seems to be an unstable OC... you mentioned +135, have you tried say +50? I have played with various OC's with Crysis 3, nothing extreme, but didn't run into any crashes. So far haven't needed an OC though, just for fun and testing. :thumbsup:

 

+ 1 for this.

 

Try some other taxing games before you reach a final conclusion?
What driver are you on?

 

If you are using the GTX 780M, then its possible you can't really overclock it anymore from stock clocks without risking crashes.
If I'm not mistaken, that gpu is a rebrand of the GTX 680M which has been overclocked at stock voltage and providing a 30% performance boost in the process, but at the same time, if it is, then its no wonder you are crashing the card with even more OC-ing.

 

No it's the full GK104 with 1536 CUDA cores like the desktop GTX 680/770. The 680M has 1344 cores like the desktop GTX 670.

 

Yeah, good point, I will. 326.80 beta.

 

Sir, if you want to see if your video card is crashing because of an overclock, do the tiniest OC possible. My video card currently crashes if I so much as put 7MHz on the core. You read that correctly. If it doesn't crash at stock and it crashes while OC'd, start as small as you can and build up to when you see the crash. If ANY OC of any kind crashes your card with certain games, then your card probably has problems working above a certain clock and having all of its loads maxed out, and the one or two games that DO crash you simply tax the areas that crash you most often. Maybe your frame buffer crossing a certain percentage of use is the problem when it's OC'd, or maybe it could be raw core power. I don't know of any ways to tell specifically, but it's worth a thought.
