Thanks for chiming in RasmusP , very informative as always
Since it's a 2 x 8-pin card it's as good as always bouncing off the 350w power limit, whether it's running at stock clocks or OC'ed. Only a couple of watts difference really.
But after reading your post I did some more tinkering and I think I found the card's sweet spot: 1890mhz at 875mV.
With the boost curve flattened at that point, core frequency stays pretty much locked at 1890 under 98-99% load without downclocking, whereas before it was constantly fluctuating.
It's still flirting with the power limit though...averaging 346w and occasionally peaking over 350. Might have to go for something like 1860@850, or drop the +500 on the memory. But then again, my main goal now is achieving the highest stable average core clocks possible, not lowering power consumption as temps are good.
So far it seems stable in Heaven benchmark (2 hour loop) and TimeSpy (benchmark & stress test), now I need to test it in games to determine final stability.
