[SOLVED] ASrock X470 SLI does not allow my memory to go over 2700Mhz ?

[nutan_world]

Hi,
I have the following configuration on my system:

Asrock X470 Master Sli with latest bios 4.30

DDR4 16GB (2x 8192MB) Corsair 1 73,92 73,92 Vengeance LPX DDR4-3000

DDR4 32GB (2x16G) Corsair Vengeance LPX 3200Mhz (cmk32gx4m2b3200c16)

This configuration over 2700Mhz makes my bios reboot and come back to auto memory speed values (2100Mhz).

I read somewhere that I can only push up to the lowest speed of the different ram memories, in this case 3000mhz. But clearly not even there my system is allowing me to get to.

I have tried XMP settings with up to 1.39v but still it doesnt work ?

Mixing RAM can have surprising effects, usually not good, that's why nobody would recommend it. DDR3 was much more forgiving.
