Ryzen 2200G Vega Drives crash windows when RAM speed is above 2400

System specs:

  • AMD Ryzen 3 2200G
  • ASRock AB350 Pro4 ATX mobo
  • G.SKILL F4-2666C15D-8GVR (DDR4 2666\Timing 15-15-15-35\CAS Latency 15\Voltage 1.2V)


RAM is detected at 2133 by BIOS.

I can change to 2400 or 2666 using XMP profile and base OS appears to be stable.

Also, Passmark memtest86 reports no errors in 4 complete passes when running at 2666.


However, as soon as I attempt to load/install the Ryzen Vega display drivers (tried multiple versions) the system crashes with a black screen (signal still goes to monitor).


On a new OS build running 2666 when installing the drivers I get the black screen crash during driver install.

If I do the configuration with RAM set to 2133 then everything works, but when I switch back to 2666 I get the Windows logon screen for about 2-3 seconds on boot and then it crashes black again in the same way.


I don't understand how Windows seems completely stable and Passmark passes all tests at 2666 but the system crashes when attempting to use the drivers.


Is this really a memory issue?  I have some people saying that the APU may be bad - but if that is the case why does it work at 2133/2400?
