F4-3400C16D-32GTZ with Asus ranger mobo

[ram-user]

Hello,
I have buy a kit

2x16go 3400
F4-3400C16D-32GTZ

But i can't put 3400Mhz with XMP profil (it's don't boot)

My config
I7-6700K
Asus Maximus Ranger (3400 OC / slot / 16Go max by slot 64Gb maxi on 4 slot)

The maximum possible for boot it's :
DDR4 3066
CPU ratio 41

I have put DDR4 3400 with CPU ratio 34 (it's boot)
But I really want a ratio CPU 42-43 with DDR-4 - 3400

Do you know what's happen, if i must change something on voltage or in advance tweaking ?

Thanks, sorry for my english...

Do you have the latest BIOS/EFI?

We have that motherboard tested for a maximum of DDR4-3000 with 16GB modules.

Only Extreme, GENE, and Deluxe model can support full 3400 specs.

Hello,
it's work now, I have put 3,5V fixed for ram (XMP put only 3,4, it's not enough for a good run)
