GTX 690 Overclocking

[dblinkhorn]

Hey guys,

I just got a GTX 690 and I was just wondering about my OC results. So far I've only been able to get +115 MHz and that's with maxing out of voltage @ 1.175v (and 135% power target for everything). +110 is possible without touching the voltage, but nothing higher. With the increased voltage I can also get +375 on memory, but only about +150 without the voltage bump. From the bit I've been reading, it seems like the average is about +150 core and +400 core. Is my +115 within the normal range of max OC on these chips or did I just get an unlucky chip?

Thanks!

The real story is the actual clock speeds in game. Enable an overlay like precisionX has and watch what your cards clock to at various settings.

They vary so much it's hard to tell - especially since the actual boost clock for each card is different. Instead of reporting your offset, you need to compare the actual final boost clock (as +115 on your card may be the same final clock as +150 on someone elses). Also, changing the voltage on the slider doesn't really do anything, it'll run at 1.175V no matter what you select there.

The highest I've seen on either card is 1189Mhz and that's with the +115 offset. Is that really true about the voltage? Why do they even put in the option to change the voltage if the card is already doing it?

Actually if you look at voltages while adjusted you will likely find it running at a lower voltage than what it does without adjustment. Seriously don't touch that slider unless you have a Lightning or PE from MSI.

All keplers are voltage locked, touching that slider does nothing. All 680 / 690 cards run at 1175mV at max load unless they are throttling, there is no need to mess with the slider in precision. You cannot adjust voltage any kepler cards, except the msi lightning.

Okay, I'll keep that slider at default. I guess since I'm getting close to 1200Mhz with boost that's probably a decent OC for this card, and I got a lot out of the memory, too.
