You might want to revisit your GPU OC then. Sounds like it's not stable enough for the harder tests.
Nah, it's the missing (or corrupted) SystemInfo file i learnt about, Googled for it, gave me that info; Futuremark support says it happens with any test, when Win 10 Fall Creators update installed, this thing messes with SystemInfo file or some such shit. Will do a more thorough research bout it.
Thanx regardless.
Valley might not be that demanding, even though it should be with it's lush terrain, rain & other effects, but Heaven 4.0 is still a resource hog to this day, i would prefer it over any Fire Strike, Time Spy or any other 3DMark test any day: the entire "continent" filled to the brim with DX11 tessellated goodness. Time Spy Extreme - now that would be more appropriate, (4k & DX12) but i haven't "upgraded" ($$) to Advanced edition yet, so.....
P.S. Checked C:MD again, CarMODgeddon mode, with this GPU OC profile, runs great. Even funnier than that, it actually runs like charm after i uninstalled 3DMark in it's entirety.
Also, Time Spy Extreme reserved for multi-GPU/multicore rigs, with CPU & GPU(s) OC'd, plus one needs a 4k monitor, one i'm eyeing for now is
this one - a 4k, 27" LED IPS goodness & with prices for PC components "not declining" (for a lack of a better word) i don't see myself using that particular test or 3DMark in it's entirety this week, or even next few months. Again, thanx regardless, cheers.
