Question Need assistance to have Infiniti Fabric running at 1:1

[Mir96TA]

I am trying to figure out why infinite



Fabric is not matching with memory
What do I need to do for FSB😀ram to run 1:1 ?

Thanks for the assistance

Look for something in the UEFI related to infinity fabric frequency and dividers. I'm not sure what brand board you have but on Asrock boards that's in the overclock section together with DRAM OC and XMP settings. On these Asrock boards, the auto setting does 1:1.

As it has indicated in CPUz it Gigabyte B450 Arous Pro WiFi
Infinity Fabric divider

I checked one of the Gigabyte systems I have on hand and the "System Memory Multiplier" is set to "Auto" and so is the "Infinity Fabric Frequency and Divider".

I have manually dialled in following

I don't know what to do for coupled mode.
Before it was set for Auto, then I changed it to 1800, half of 3600
now 1900 set it up for half of 3800
Which is half of it.
I am not sure what do I need to match it ?
CPU Clock ?

.... go back, and read the definition of "double data rate"? You're doing well, if you have 3800 RAM synced 1:1 with 1900 FCLK.

You can confirm with ZenTimings:

I am curious what VSoC you are running for that level of FCLK? You will want to be sure it is not too high if left on auto.

That is a ridiculously high fclock for Matisse.

I got troll by CPU Z memory.
Zen Timings got me stand corrected.
Thanks Cake Monster

I would like to answer you, however I do not understand what you are asking ?
Are you asking did I adjust voltage to VSoC ?
The answer is no. I dont know, if I need to or even know where that is.
Can you please share, how I can answer your question ?

VSoC is the voltage for the memory controller, IF, etc, on the IO die for your CPU. Sometimes you will need higher VSoC than default for higher IF clocks, such as 1900MHz and higher.
From the post above, it looks like it is 1.1 Volts. That is fine.

Understood.
