Yes, it is stable at that speed. Well, last time I checked it was still an improved FPS indicated by Heaven at that high memory clock so no I'm not yet hitting GDDR5 memory correction. Although, I have to double check on that.
Setting at 250W will not damage the card at all. It's basically setting the max limit and the draw is ultimately dependent on the card load anyway. Increasing the GPU clocks more will produce a crash in Heaven and increasing the mem clocks usually produce artifacts OR a Heaven crash as well. Does that mean voltage problem? Or can using KBT 1.27 to adjust the power throttles alleviate these?
If you can reach higher speed for gpu while leaving memory at 3000 or even under, then might be power, but i guess if it is stable at that speed then you are probably near max and power problems might start only after voltmod with higher clocks, if even then...
I got to 3750memory with 760 and 770 bios, but do not know if the timings or different os something, because i get better result with 670 bios at 3400 vs 770 bios at 3750, while at same gpu speed, but with 670 bios i see first errors at 3500, nothing at 3750 with 760/770 bios, only crash at 3800
