This was a really interesting post (!) maybe there is a hope for a new official bios after all but it has to be some very strange complicated issues taking such a long time?
Not sure if PBO settings are doing anything for me either but I an not concerned at all since performance is good enough anyway.
Yes, 3600mhz RAM for me too and good benchmarks as well. I don't think the 5406 (test/beta bios) gave me better performance but maybe better stability. There have been other updates since then though, Nvidia, AMD chipsets among others but I haven't reinstalled Windows 10.
Everything is running really well currently, long time ago since I had a crash. Been playing some PUBG and CS:GO and not having a single crash. If not even PUBG is crashing then something strange is going on ;-) (but maybe PUBG's latest patches helped stability, not sure). CS:GO isn't saying much though, probably one of the most stable games in the world? ;-)
My guess is that a majority of stability issues for Ryzen systems is because of RAM issues. Many trying to tweak their RAM but they end up with settings not 100% stable.
Not at my computer right now but CR20 multicore is almost exactly 5000 (slightly higher).
TimeSpy is between 10300-10800 depending on how I configure my GPU (aircooled 1080Ti).
PCMARK 10 scores between 6835 - 6924 depending on current configuration
It's funny how a cheap X370 board deliver almost the same performance as expensive X570 boards I think? The difference in running a 3700X on a good expensive X570 board comparing to this X370 is probably very, very small performance wise. For really beating this board you will have to have really good RAM and also correctly configured otherwise small negligible difference. I believe this board will run well on all Ryzen 3 series CPUs with possible exception from Ryzen 9 3950X (not sure about compatibility with this one).
It's a bit funny if people ditching this board for more expensive X470 or X570 boards without gaining almost no performance? ;-) Maybe this board (at least higher RAM speeds) wasn't perfect for Ryzen 1 series but it is certainly a good match for Ryzen 3 series.
All we want is a new bios but I am not stressed at all about this since my system currently is running very well. :-)
