Hi,

I have Crucial 8GB DDR4 3466MHz CL16 Ballistix Elite 1 stick only (2nd is on it's way) and XMP only works if I put it in A2 slot. Works fine at 3466 CL16. If I put it in the A1 it won't go past 2133.

Do you have your sticks in B2/A2 slots? The manual shows this is the proper config for 2 sticks.

EDIT:

From: http://forum.asrock.com/forum_posts.asp?TID=7798&title=asrock-z370-k6-gaming-ram-slot-issue

The solution was IO-L Init Value. Can somebody explain the IO-L Init Value?
You can find it in the OC Tweaker 4th Timings.

I changed the standard value (auto=4) to 5.

Now the modules run at 4.133mhz at specified Timings (A2 B2 socket).

I downvolted the kit to 1.35v. primestable for 1 hour now.

So the kit runs nicely on this board but i ve no clue what the IO-L Init Value does.

even 4.266mhz boot so far 1.4v

Hello,

i have problem with speed of my ram Corsair Vengeance LPX DDR4, 2x8GB, 3466MHz, CL16 (CMK16GX4M2B3466C16) - when i set up XMP profile with standard 3466MHz after PC reboot it restarts to 2133MHz.

But when i set up XMP profile and manually choose to 3100MHz it can run.

I also tried to switch ram voltage to 1.5 V but it didn't help.

Bios is updated to the newest version (1.80)

MOBO: ASRock Z370 Gaming K6
