Warning!!
Below beta BIOS should only be flashed at your own discretion.
You could give it a try if you have good knowledge of BIOS and computer but generally speaking, please follow the information on MSI official download page of each model.
MSI BIOS Release Naming Rule Example: E7C34AMS.1B1(Beta) -> E7C34AMS.1B2(Beta) -> E7C34AMS.1B3(Beta) -> E7C34AMS.1B0(MP) -> E7C34AMS.1C1(Beta)...
It is possible the BIOS here is earlier than the BIOS on product page!!!

AMD ZEN3 5000 Series on X570 ACE/UNIFY/CREATION FCLK max out at 1600 (RAM Frequency: 3200Mhz) problem Update
Workaround: Update to latest beta BIOS on MSI website
Beta BIOS allows FCLK to go up to 1900, higher depends on CPU quality
If your FCLK can reach 1900 before updating beta BIOS, there is no need to update BIOS

Windows Event Viewer Error (Even System Restart)
Note. This should relate to individual AMD CPU but not motherboard
Symptom: When FCLK is higher, system is more likely to receive WHEA Logger error and sometimes can end up with BSOD and reboot.
Workaround:
WHEA Logger Error 18: Add a little vcore offset in BIOS (ex. +0.05V) or flash to AGESA ComboAM4PIV2 1.1.9.0 if it is available
WHEA Logger Error 19: Lower FCLK for now and wait for future BIOS update

MSI board
Gigabyte board
ASUS board

Solution: No ETA

Memory with RGB cannot be found in Mystic Light (DC)
Note. This issue should be common issue on all motherboard vendor
This issues are seen on some RAM when Ryzen 5000 CPU is used
1. G.SKILL F4-3600C14Q2-64GTZNB
:cry: With 5800X = DRAM RGB lights up, but DC does not see DRAM and is unable to control RAM LED
:biggthumbsup: With 3600X = DRAM function is all good and DC can control LED
2. Corsair CMW32GX4M4C3600C18 v4.31
3. HyperX HX436C17FB3AK4/64
4. Crucial BL8G30C15U4BL.M8FE1
:biggthumbsup: 2, 3, 4 all pass, DC can control RAM LED

Solution: DC 2.0.92.0/Mystic Light 1.0.0.99

USB Device on Front Panel Stutters When FCLK Goes Higher
Note. Rear USB port does not have such issue (User reports rear USB port can be affected)
Symptom: Problem can be seen on specific peripheral (especially those with RGB solution), USB device becomes unresponsive once in a while. Problem also disappears when system is under loading.
Workaround: Disable BIOS\OC\Advanced CPU Configuration\AMD CBS\Global C-state Control
Solution: AGESA ComboAM4PIV2 1.2.0.2 BIOS
