Hello.
My configuration: CPU is i7 8700K.
Motherboard Maximus Hero X.
Ram DDR4 Ballistix Elite 16GB Kit (2 x 8GB) DDR4-3466 UDIMM BLE2K8G4D34AEEAK Specs: DDR4 PC4-27700 • 16-18-18 • Unbuffered • NON-ECC • DDR4-3466 • 1.35V • 1024Meg x 64
I updated the bios to the latest version.
By default, the memory operates at 2133.
If i go more than 2800Mhz, or load my XMP profile, the system won't boot.
If I manually set 16 - 18 - 36 and the 2666 system works well.

If possible please tell me the solution to my problem. Thank You.*

Have you tried enabling XMP with just (1) stick ....(Tweak Mode 1 if supported by board) and manually applying dram voltage @ 1.35v with 3466 mhz ? ...Just throwing that out there cuz I've seen some boards that would not post at rated speed if 2 sticks where initially applied with set frequency but would post with 1stick on reboot....and applying 2nd stick afterwards...just something to try.

Yes I tried it, in each of the 4 slots.

Did an Rma fix your issue? I have the same problem of 1.088 vram. I'm sending mine in soon. I already have a Rma set up.

If you did sent it in, did you need to remove the m.2 nvme shield? I'm not sure if I should leave it screwed in or not.
