Hey all....
 
I have a Z370 FTW board that's giving me some issues.  I went through the comparability list and picked out an i7 8700k (Coffee Lake).  
 
When it came to picking RAM I went through G. Skill's site and used their tool to pick out memory (model number F4-2666C15D-16GVR).  Ordered it up and didn't think to check the list on EVGA's site for compatabiltiy.  While it isn't specifically listed it has all the specs that the board should want/need.
 
Get it all together and crank it over for the first time and I'm getting a "4C" error to start with then it flashes through a few other errors (including an FF).
 
I've gone over it all a bunch of times and nothing seems out of sorts.  However I'm not seeing anything about what the "4C" error is.
 
Thanks for any help you can offer.
