Random shutdowns when gaming overclocked

Hey everyone

I'm getting random shutdowns while gaming overclocked. All my temps are perfectly ok (CPU <65C, GPU < 73C) so its not a typical shutdown.

I'm not sure whats causing it. Drivers definitely have something to do with it, but dont fix it. Different (older/newer) drivers can last anywhere from 30 mins to 2 hours before it shuts off. But no driver has fixed it.

When it shuts off i get no BSOD or anything. Just instantly everything turns off and restarts after a few seconds.

My overclock is not anything crazy. And the temps are way under normal for gaming, so i dont think thats the problem. Its a 20% overclock to 810/630/1620. The same OC XoticPC guarantees on their laptops.

Thanks for any help in advance.

 

What clocks are you using? Lockups/crashes/shutdowns will most likely be related to the Core/shader clock, memory clocks unless raised too high should just artifact.

 

Nope no artifacts, gameplay is normal and runs great.

Clocks are what I listed, 810/630/1620. Xoticpc puts that OC on thier g73s and garuanees it, and so I don't think it's too much for it to handle. Especially with the temperaturs being so low . I tried lowering it down to 800 core clock and the corresponding shader clock, had the same result.

I read something about the VBIOS possibly being an issue?

Thanks

 

Your OC is unstable, and the blank screen is the drivers resetting from an error. Dial down your overclock.

And no one overclock setting can be guaranteed. New games + updated drivers can change the stability of an overclock. Plus do not forget the aging of a component.

If anyone at XoticPC told you this, then that's the 2nd bad practice I've seen them do.

 

810/630/1620? That would be core/shader/memory in mhz correct? If so, then how the hell did you oc gpu memory to 1620mhz and NOT get artifacts? hmmm.....

Truth right there.
My default OC is 800/1100, stable for any game, but while playing the Witcher 2, the screen would sometimes go black (at least once every 20mins) anywhere between 5-10 secs with audio still in the background, and then everything would be normal again like nothing happened. No crash, no error. Just a black screen pause.

Culprit: OC. Set clocks down to 790/1090 and never happened since.

 

Ok my bad, here is my source for that information though, not from xotic themselves .

As for the clock speed questions mine match the gpuz screenshot on that page ^

I chose those clocks because I figured they are pretty stable if they were "backed by a seller "

I will lower my overclock and stress it later today

 

Different GPU than ours.

 

They have to be changing the voltage and or Vbios settings to be able to guarantee a stable overclock because every chip is different and produces different results.

That post also does not say what will most likely be in their small print that they cannot guarantee this against changes in drivers/software/games its probably that its stable during a stress test or benchmark.

That is Core/Memory/Shader for the Nvidia. The shader is always double the core.

 

Weird lol




But anyway that must have been the problem. Lowered my clocks down to 775/628/1550 (Screenshot attached). Stressed for hours since i made my last post and that seems to be the stable one. Currently running the best drivers that worked for my previous overclock (267.76). So I'll have to try the newest drivers and see what happens with them.

Thanks alot
