z790 Dark Hero - won't boot with XMP Enabled

Hello all, 

I'm having an issue with my new build where the system won't boot with XMP enabled.

Specs:

  • Mobo: ROG MAXIMUS Z790 DARK HERO
  • CPU: i9-14900k
  • RAM: Corsiar Dominator Plantinum RGB 64GB - 6400 MHz (CMT64GX5M2B6400C32)
  • Graphics Card: ROG-STRIX-RTX4080-O16G-GAMING

Before purchasing mobo, CPU and RAM, I reviewed compatibility. The RAM kit is listed on the HCL for this motherboard on ASUS's site for 14th gen processors.

It boots fine on bios defaults, but when I enabled the XMP profile it tries to boot and seems to go into the memory training process and will run the process for a while but then eventually stops with Q code 55.

I have updated to the latest bios for the board (version 0506)

Any thoughts?
