6000 MHz Memory Kit is not running in 1:1 mode on ASUS X670E Hero

Jobrick3
Level 7

This is my setup:
- AMD 7905X
- Asus X670E Hero
- Vengeance DDR5-6000 96GB Kit, CL30-36-36-76, 1.4V, Intel XMP Profiles (CMH96GX5M2B6000C30)

As far as I understand, all memory up to and including 6000MHz should run in 1:1 mode with AMD 7000 processors.

My 6000MHz kit does not automatically run on 1:1 mode (MCLK = UCLK). Instead, it runs at 2:1 mode: MCLK is 3000MHz and UCLK is 1500 MHz. The MCLK/UCLK ratio is set to "auto" in the BIOS.

Can you please advice what to do? Why is it not running automatically on 1:1 mode and can/should I set the MCLK/UCLK ratio in the BIOS manually to 1:1? Is this a known issue?
