if they are both the same then your best bet is to run them in the same timings as the amd certified ones like 

CL14-14-14-34
CL16-16-16-36

Info was about problems with  memory management.

Lost work in host and in virtual system.

Something is wrong beetwen this motherboard and corsair memory.

Maybe my bad decision that I bought corsair memory. Damn 

Didn't suspect such great incompatibility 

Can someone recommend me memory which work with this mainboard at 3200MHz but from experience not from compatibility sheet ?

nothing changed ?

but before you had windows crashes now none you mention

that seems a big change to me

After few tests on new OS nothing really changed , system is stable on 2933 Mhz .

I could raise to 3066Mhz and somewhere here is red line which I can't accross. Even with highier voltage.

Achieve 3200 Mhz seems to be beyond reach . 

Also nothing changed with soundblaster features, I have audio but can't use sounblaster features. Drivers  don't recognise sounblaster with last bios upgrade. 

So a lot of work and nothing really changes. 

ok follow these steps please

grab a usb stick (8gb)

go to windows media creation tool webpage (use google to find)

follow instructions to create a bootable win10 usb (make sure you select the version that you have the serial for  (it is win10 64bit ? )

then do a fresh clean install (this will not need loads of updates as it will be the current version)

next go to amd support direct and grab the chipset drivers

now back to windows and use windows update for any remaining drivers

DO ALL OF THIS ON STOCK CPU AND STOCK RAM SETTINGS................

if you have an ssd AND  a large storage spinning hard drive it seems prudent to actually install the os on the large drive and then use the free x470 program for combining drives for ssd speed

Than I come back to issue with unstable memory at 3200 Mhz but I afraid that without resolving it in bios it could be impossible. I see alot of topics with problems about memory with Ryzens and poor support from AMD in these cases. I didn't suspect that is so big problem 

Issue nr 2. Not working sounblaster features after bios upgrades. I think it's a problem with old drivers for realtec. With bios upgrade nobody changed drivers . But it would be nice if someone from Asrock can confirm it.

I couldn't agree more. Windows 10 is fiddly at the best of times, downright obnoxious when you are not running a fresh install on new hardware. 

Literally every issue I have had with my Ryzen system turned out to be Windows 10 related, not hardware (aside from RAM speeds). I had intermittent 10 - 40 second freezes, replaced every component in my system, reinstalled windows upwards of 10 times and nothing cured it. Eventually I put the original config back together and tried one last fresh install, I had lost my install USB so downloaded the latest Win 10 installation and made a new one. Problem solved. Turned out it was an update that was failing to install on my older install medium. I tested by reinstalling on another drive with the old USB installer, the problem was back.

The moral of the story, always download the latest install medium and make a clean install when you upgrade major components, especially motherboard. 

the ram could maybe make the 3200 speed using the ryzen dram calculator but i wouldnt advise this on a basically unstable windows install,we have seen time and time again problems with win10 when used on a new system without a clean install

which is exactly why i asked that question
