Just out of curiousity, what makes your GPU go 100%?
In Turbo mode memory should clock +150MHz, 7151MHz would be the case.
With issues many now are having, GPU is lowering to "power saving clocks", that it reducing GPU Memory clocks with 1000MHz, and Core clocks to around 500-750MHz
I'm sure our GPUs are fully working within weeks. There are tons of new updates at Asus download site, they working on it.
