Hi Guys
Exactly the same issue here:sigh!:,
Mobo Asus Z170-A (BIOS 1203 latest)
RAM Kingston DDR4 2666 4x4GB C15 (HX426C15FBK4/16)
yes i know it's corsair forum and Asus z170 pro gaming mb thread, however the issue\symptoms are regardless ram/mobo, its seems as Z170 chipset or mobo issue.
1st step : XMP 2666Mhz - no errors
2nd step :
I've found this thread

so I setup my RAM 3000 15-15-15-35 1N 1.30V and is 100% MemStable i can run 8h test and there is no errors at all :!:
System is stable games/all memory/cpu test etc...
However as NJC mentioned "cold start" is total lottery, sometimes boot up sometimes won't :evil: waiting for another Asus BIOS.... :[pouts:
