Hi Everyone,

I just upgrade my PC with a Z270E Strix, i7-7700k and 2x16Go 3333Mhz RAM
Everything works great but, when I choose the XMP Profile 1, I can't boot..
I don't have the POST.. and the PC won't boot..

What is the solution ?

I Run the Latest Bios (1009)

Thank you !

DDR4-3333 requires some manual tweaking on some CPUs. Start with your VCCIO and SA voltage.

DDR4 frequency range	Required CPU VCCIO Voltage range	Required CPU System Agent Voltage range
DDR4-2133 ~ DDR4-2800	1.05V ~ 1.15V	1.05V ~ 1.15V
DDR4-2800 ~ DDR4-3600	1.10V ~ 1.25V	1.10V ~ 1.30V
DDR4-3600 ~ DDR4-4266	1.15V ~ 1.30V	1.20V ~ 1.35V

Probably requires more tweaking.

I just try Every Values between 1.10V and 1.25V (0.1 by 0.1 V) for VCCIO
And the Same for SA from 1.10 to 1.30 (0.2 by 0.2 V)

And I'v No boot..

If i do a CMOS he boot without issues
