"My initially favored ASUS Prime X299 Deluxe also has only 8 plus 4 PINs. My goal of 4.7 GHz with a cache clock of 4,000 MHz seems hardly accessible with the board.
Also the heat development (105 ° C @ load), which I always feared, in the SpaWas of the board, seems to have been confirmed. As it currently looks, sufficient cooling for a good 24/7 OC is not easily possible.
This is a crucial disadvantage of the Skylake-X. Nevertheless, I would not buy because of the bad gaming performance no thread-Tripper."
