I gained clock speed beyond this. I got my core clock to 765 stable with no memory overclock, and I had no artifacts. How I did that is beyond me, but my card was running at like 52-53c idle, and like 78c load, so that was way to hot opposed to it being at 725 and 1300 memory and being 42c idle and like 55c loaded.
