Xmp profile 1 cannot be enabled without boot failure.

 

Z170x-ud5 gigabyte with f5 bios.

 

Won't run at 2666. Only at 2133.

 

Which specific kit do you have, and have you tried F4 bios or just reflashing F5?

Vengeance lpx 2666 ddr4

 

2 8 gig sticks.

 

 

What is the specific kit part number?

 

Do you have 2 of these modules?

I fixed it.

 

Turns out if you are running two sticks they need to be in channel 1 and 2 on the board. I had them in 3 and 4. No good. You cannot enable XMP. Now im at 2666 and overclocked on the cpu.

 

Should be in 1 and 3 as far as the slots on the motherboard go.
