So according to reamde I should try 2816 x 4 and 5 =  11264 14080 tc. Low results here.
If my math isn't off the overclockers guy uses shaders x 11.63 ish and thats way off according to readme.

The readme don't always apply 100% (sometimes way off) to find the sweet spot. I am wrong here?
Can cards really differ this much or is this a problem with win 8.1 and or AMD drivers??
