B550 BIOS question(s)

I am trying to learn about all of the BIOS entries as I get familiar with my new systems. I have one with a B550-I and another with a B550-F (wi fi). Under the "Advanced" section of the BIOS is a sub section title "DF Common Options." What does DF mean? Is there someplace where I can get information on "Scrubber", "Memory Addressing," "ACPI," and "Link?" Any feedback/direction would be appreciated.

Okay, I believe DF stands for Data Fabric. Does that make sense? Within Ryzen's architecture, the Data Fabric controls the communication between CCXs and Memory. Given the options that are available under this section, this would make sense. Anyone with thoughts on this?

You are right about DF.
Most of these bios settings can be found by just googling them, but there are some interesting documents:

That last one is the ASUS BIOS manual for B550 chipsets

Thanks! The first link I had already found and I have no shortage of Asus BIOS manuals. That second link has some really valuable information that will be very helpful. I appreciate the response. For the most part, the internet has been my friend when it comes to figuring out some of these settings but "DF Common Options" was a killer to sort out. Once I got Data Fabric, that opened up a bunch of additional search items. It is interesting how few people actually understand all of these options and, unfortunately, the motherboard manufacturers do not help with their cryptic BIOS manuals. I am continuing to grind through all of the entries and I am learning a lot along the way. Thanks again!
