Upgrading a X370 Fatality Professional Gaming

I don't know.
Without this support from jzelectronic.de the Asrock world would be much poorer...

Did you do it at default bios settings? The guy at asrock said as another poster above said, is to only boot up at 2133mhz memory settings but he said the x370 professional gaming would boot up..

Yes. I tried many variants. CMOS reset, switching another memory, using only 1 stick of memory, disabled m.2 ssd, disabled Reset SW cable, switched to another videocard. More then that i even tried manually set ram speed to 2133 on both sticks of different memory using ryzen 1600. Once you install ryzen 3600 and nothing happens. Very very very sad for Asrock.

Update Microcode AMD AGESA Combo-AM4 1.0.0.3 https://shop.jzelectronic.de/news.php?id=1563435396&sw= Have these been tested to work and not brick boards? It is the same as Taichi X370 Beta Bios L5.61 with Combo-AM4 1.0.0.3 If you fear to brick the board, you anyway should not try to use the board with a new Ryzen until Asrock comes with the total final bios version and some users are saying: "Yes, everything is running fine"

I'll give it a try when my 3800x gets here.

I'm currently on bios 5.3 and everything works as it should with 2933mhz memory. The Asrock technician said the 3800x would boot up fine on 5.3, but it would only boot with memory at 2133mhz frequency..

Thanks.

Somewhere in Reddit I saw suggestion about infinity fabric clocks, for now only 1500mhz is stable...I do not know all correlations of the system but guess that infinity fabric clock speed is half from RAM speed, so 3000/2 = 1500mhz match with my settings.

yes, its double data rate memory ie:DDR, and the infinity fabric runs at native speed. which if youre running 3000mhz memory you'd see 1500mhz on the infinity fabric... That's why they say the lowest latency and 3600mhz memory is the best to run on Ryzen 3000.. 3200mhz and 14cl would be a good base supposedly

Im running 3000mhz (2933actual) at 15-15-15-36or35 so i might see a 2 or 3 fps loss from 3200mhz 14cl memory, but I could never get the Flare-X 14 cas latency memory to boot on my board, no matter what I tried it was never stable.
