If you put the clocks back to default and it stops crashing (with no other changes) then yes, I'd say it's most likely related. Something to keep in mind is that certain 1070 cards got Micron memory rather than Samsung, due to a memory shortage during manufacture. As I understand it (I have a 1070, too) this is really only a problem for those trying to overclock - not sure it that's related to your problem or not. There is an excellent utility called GPU-Z that will identify the type/brand memory on your card, good to know info. You can find it at TechPowerUp (
HERE) - very reputable utility, universally respected and trusted.
Overclocking, generally, has become far easier because it's very popular, so the manufacturers make utilities just for that (MSI Afterburner, eVGA PrecisionX, etc). Of course, just because it's easier to do, doesn't mean it's simple: Anyone can use these tools to overclock, but the real issue is getting a
stable overclock (be it CPU and/or GPU). That takes a lot of testing under various conditions to ensure, and a lot of people want to take short cuts and not test properly for stability.
As for as WOFF and overclocking, it is apparently more sensitive than most other programs about overclocking, according to what the Devs have posted. They have consistently warned about overclocks, and that "just because every other game runs fine doesn't mean anything". This would indicate WOFF can have problems with overclocking, even if everything else seems fine. According to the WOFF FAQ, their testing methodology shows overclocking causes issues like stutter.
My own $.02 is that if your overclock causes issues like this, then you're not doing something right (
and that includes software you're running, too). Yes, there are endless accounts all over the internet about how overclocks cause this and that...which goes back to my point about how easy it is to do these days, but not necessarily easy to do right. There are scores of machines I overclocked out there running right now with ne'er a complaint, playing all sorts of games (almost every machine I build is used for gaming at some level, and the majority are overclocked). PUBG, BF1, Squad, Overwatch, Fortnite, ARK, GTA5, RoF, WoP, FE, etc...
No crashes.
No stutters.
No problems.
Fortunately, these days it's fairly easy to disable an overclock, and settings can usually be stored in a profile, even for BIOS-level overclocks. That makes trial-and-error troubleshooting a lot easier.
Good luck.
