I was used of having huge headroom for oc with AMD. With thuban you could easily squeeze 1 Ghz more on the 1090T. With Vishera, you could even go past the magical 5 ghz limit on water. So I was expecting a little more of Ryzen. I mean, if you consider the turbo, you only win 200-300 mhz. It's very small margin. But who knows, they might work this out in future Ryzen stepping.
