2.20 @ Fatal1ty X370 Gaming K4

it works pretty alright, it reset my 3.9gh oc and my 2666mhz (F4-3200C16D-16GTZB) ram oc, ill see if i can get my ram to 2993-3200 and ill get back to this post

Save your OC settings before you update BIOS


****************EDIT******************
post times seem to have become faster
single thread performance was a slightly better on cpuz bench test
XMP profiles still don't seem to work with my ram (cant overclock my ram past 2666mhz manually)

All these new Ryzen board updates seem to have is an update to the AGESA string to 1.0.0.4a, but as we know the update description does not cover all updates, unfortunately.

I'll be trying the similar 2.30 version for my board.

You say that POST seems to be faster? That is certainly welcome.

The XMP profiles for DDR4 memory that was released before Ryzen, and designed for Intel Z170 and Z270 boards, like your F4-3200C16D-16GTZB, tend to not work with Ryzen systems. The main thing seems to be the Command Rate (CR) XMP data is always 2 for Intel, while Ryzen prefers a CR of 1 for memory speeds above 2400.

I use G.SKILL FlareX 3200 memory, supposedly designed for Ryzen, and so far the XMP profile does not work. Or at least it won't work at 3200. All we can do now is set the timings, speed, and DRAM voltage manually. Also, increasing the SOC voltage from the default 0.900V apparently helps with higher memory speeds. The voltage to use is a pure guess, but I've seen people use 1.4V or more. I'm NOT sure how safe that is, so please be careful if you try increasing the SOC voltage. That is similar to increasing the VCCIO and VCCSA voltages on Intel Z170 and Z270 systems for higher memory over clocks.

One thing I must say about saving the OC settings before any UEFI/BIOS update, which is good advice, is this. All ASRock UEFI updates will remove any UEFI profiles you have saved from the previous version. That's because the existing profile may not match the layout of the new UEFI version. So saving your OC and other settings must be done manually, by writing them down.

Another thing you can do is put a USB flash drive in a USB port on the IO panel, and when in the UEFI UI with a screen displayed, press the F12 key. That will save a picture of the screen (only what you see on the monitor) to a file on the flash drive. You should see a message that the screen image was saved after pressing F12.

I tried 2.20 today and so far, I only saw that I couldn't run my memory at 2933 anymore. 
Before, I used to run 2933 with 1.35V and CL18, now it works fine at 2666 with 1.20V and CL16.
