I have ASROCK Z170 PRO4 v 7.50 If I add DDR4 to either , or both of the 2 slots closest to the CPU, system boots, and everything is OK . But this is highly undesirable because its not in DDR mode. and I can't use all four slots. If I add a stick to either or both of the other two slots, the system will not post. It just sits there doing nothing forever, but I can sorta hear the CPU fan surging. I've tried the same two sticks that worked in the first two slots in the others, so I know my memory is OK. Ideas?

Have you tried reseating your CPU? While you have it out of the system check the CPU for any warping/bending of the substrate (the green PCB). Intel switched to a thinner substrate with the release of Skylake and it had a nasty habit of warping when too much mounting pressure was applied by the CPU cooler. Some critical memory controller connections (contact pads) on the CPU are located on the outer corners. -------------
