Got my Gigabyte GTX 1070 WindForce OC today, already wanting a custom BIOS.
I can't really get over 2000mhz core in Firestrike and the best I can get in Firestrike is 19500 on graphics score while others are getting up to 22000...
There's something wrong with my card or the BIOS is gimped, there's never any visual anomalies or artifacts and the driver never crashes but Firestrike does.
Increasing the core voltage from 1.05 to 1.09 (+100) doesn't give the card anymore stability which I don't understand, and smashes it to the 111% power limit in Firestrike.
Constant VRel perfcap...
Unigine Valley isn't as demanding on the power and voltage limits so it can get a bit higher, but randomly restarts during the benchmark at higher clocks despite no visual issues.
There is no voltage drop or frequency spike prior to any of the benchmark crashes, they're quite random.
Maybe I'll have better luck in games but I doubt it. I've only found 1 other user of this exact card that has the same issue, though at higher clocks of around 2060mhz in Firestrike.
Sudden hard crash for no reason when everything is visually solid. Artifacting should be happening far before crashes so this doesn't make much sense to me.
Here's GPU-Z when the Valley restart happened midway through.
I've not touched the memory and only increased the core in increments of 10mhz. I got to 145mhz stock voltage and that was the first crash in Valley, raise the core voltage +100mv and it still happened, no added stability or overclocking headroom from the extra voltage.
Also apparently K-Boost is exclusive to EVGA cards this time around, they locked the feature despite it being available for everyone with Maxwell. So I can't lock my voltage and clocks to their maximum while testing to try to make it easier by stopping all the fluctuations.
Pretty disappointed. Seems like I'll be staying around 1950mhz...
Going to go hope it's magically more stable in games and hope you all figure out how to BIOS mod these super limited cards within the next few months.
