680 Overclocking (Calling all owners!) - Page 40

post #391 of 1059
I have a little theory here after reading the thread. To put it simply those crashes when setting the offset too high are because of the GPU Boost throttling down and may be fixed in the next driver update by adding more steps until the max frequency or not throttling down too fast.

Cuz as far as I know none on the whole thread had a hard lock after a failed OC.

Would be great if someone could test Unigine enabling the frame limiter past his max stable GPU offset. Then while running it increase the frame limiter a bit and check for stability until the app/driver crash.

Sorry if I'm asking for something stupid.

So in BF3 where I was getting crashing. I did boost the FPS cap to 100. Increase all settings to max and the game bounced from 80-120. No crashing though at +155 and +400 Gonna keep pushing though.

I set BF3 at 85fps and 100fps and it worked fine. Set Precision when the game was closed though. Not sure if that's what you're saying, that the Framerate Limiter wasn't working. I might be reading it wrong.

No lag, no stuttering, and no tearing! BF3 is amazing now (coming from 570 SLI)

The limiter is not a perfect science. It makes sure the card is always working to achieve "atleast" 100FPS So any less the card works carder, any more and it will not race to far ahead. This reduces how much the card will self throttle the boost and downclocking feature.

It works fine, I just wish we could disable the boost feature I'd rather it stay perfectly stable.

So you mean that you set it at 100fps in Precision and it will downclock less because it is trying to get up to that 100fps limit?

More or less that's about the gist. But it's better then it going boost, downlock, boost, downclock in rapid succession and forcing a driver crash. Everything I've done so far has pointed towards that. But I'm sure it's gonna be fixed. It's a driver issue, not a hardware limitation.

Yeah I was thinking, EVERYONE'S overclock crashes have been "Driver has stopped responding..." or whatever it says, meaning obviously driver related. Has anyone gotten a lock up and had to reset? That's how my 570's were with mature drivers. Do all these driver crashes when overclocking mean that most of these overclocks will be stable in a few driver versions and that we won't be hitting the hardware limits until we start getting some lock ups? I mean I had drivers stop responding on me with the 570s, but not EVERY time there was an unstable overclock.

A few folks are saying it's unstable OC's. But I'm standing by my theory of rapid throttling will crash the drivers at the present state. As that's what all my tests are showing.

And it makes sense too since there don't seem to ever be any lock ups or hard resets.It's the driver every single time, and with everyone on here, I think we've experienced a TON of unstable overclocks. But not one lock up like I'd get with other overclocks all the time.

Has anyone run Witcher 2 yet?

This tech is new. Stop thinking about overclocking as what we've been doing for a few years. It's a new beast, and as such start thinking differently.
