Asus Strix Z690-A Gaming Wifi D4 - Is there an option to set Gear 1 or Gear 2 in bios

Per the title, I did not see the option to change between Gear 1 or Gear 2 for the CPU IMC.

Is this option in the Asus bios?

In the ASUS ROG BIOS, you can select the Memory Gear Ratio in the Extreme Tweaker menu under the Memory Controller : DRAM Frequency Ratio option.

In the AI tweak for a Z690-A DDR4, I see the following:

BCLK Frequency : DRAM Frequency Ratio
Auto
100:133
100:100

Memory Controller : DRAM Frequency Ratio
Auto
1:1
1:2
1:4

Do I need to change anything with the BLCK Frequency or leave on Auto?

Also, 1:1 = Gear 1 and 1:2 = Gear 2, is this correct? And what is 1:4?

I'm not sure what BCLK frequency does apart from limiting your RAM frecuencies.

1:1 means Gear 1
1:2 means Gear 2
1:4 means Gear 4

Stick to Gear 1 or 2 to best performance.

Thanks for clarifying!
