Big BIOS leap: Ryzen 2600x to 5800x3D on B450

Hey, I hope this is an easy question and I wanted to ask it for future folks that might be in the exact same scenario. I saw very, very similar questions but didn't see the below called out specifically.

Cutting to the chase.

* I am using the Asrock Fatal1ty B450 Gaming K4 on BIOS ver 3.40

* Upgrading to Ryzen 7 5800X3D.

* Have not updated BIOS from 3.40 due to not having a Raven, Summit, or Pinnacle Ridge CPU.

* [CPU compatibility per Asrock says BIOS 5.30 for that processor](https://www.asrock.com/mb/amd/fatal1ty%20b450%20gaming%20k4/index.asp#CPU)

* [Asrock's BIOS version history with notes.](https://www.asrock.com/mb/amd/fatal1ty%20b450%20gaming%20k4/index.asp#BIOS)

* BIOS version 4.50 is the first version to support 5000 series CPUs.

What isn't perfectly clear to me is the order of BIOS upgrades. Do I go straight to version 5.30? Or do I need to upgrade to 4.50 > 5.30?

*Side note:* I have a 30 series Nvidia card, so I'm not worried about upgrading to BIOS 5.60 at this time since that appears to only be needed for 40 series cards.

Lastly, I am also upgrading my memory to higher capacity/timings. I would like best practice for the order to do everything. Here is how I have it plotted out so far:

1) Install memory first and test. Assuming that goes to plan:

2) With 2600X still installed, flash BIOS to 5.30 (or 4.50 > 5.30)

3) Install CPU and pray.
