I just got the GigaByte X570 AURUS XTREME board a couple of days ago.
Before this I had (and have) the GigaByte X470 AURUS Gaming 7 WiFi and I have discussed my experience with this board and the 3600X I have extensively in the thread Definitive guide to configuring the Ryzen 3900X
Running my 3600X (which I got to gain experience with the Ryzen 3000 series CPUs) I had no problems to speak of on the X470 Board. It was running 18.104.22.168 ABBA BIOS.
When I got the X570 board I flashed the backup BIOS to 22.214.171.124 ABBA (F5b) and the main BIOS to 126.96.36.199 B (F10A)
On the newest BIOS I have had nothing but grief trying to configure the BIOS, even something as innocuous as setting the XMP profile causes the board to go nuts.
I switched over to the secondary BIOS with 188.8.131.52 ABBA BIOS and have no problems with the RAM whatsoever.
The RAM I have is four DIMMS of Team Group Edition TDPGD416G3600HC16ADC01 3600 16-16-16-36 and had absolutely no issues with it - even overclocking it to 3733 16-16-16-32 - on the X470 board.
I looked at the GigaByte site and found others who seem to have problems since "upgrading" their BIOS to the new 184.108.40.206 B version and I have to agree with those who say it is borked.
Whenever I set the XMP profile of the RAM on 220.127.116.11 B, the board goes into a round of what I assume is RAM training when it reboots and at some point just hangs, BIOS error 22 is displayed quite often, but not always.
The problem is that I will be getting the 3950X CPU when it comes out at the end of this month and a pre-requisite for running this CPU according to AMD is the BIOS version 18.104.22.168 B.
