I have tried a lot to fix this issue and also tried every available ‘fix’ out there:
What eventually ended up being the fix for me:
Make sure your RAM timings are right. I am using Corsair vengaence ram with a Hynix module instead of Samsung b-die. On my Ryzen system this didn’t allow me to select an XMP profile (which makes sure your ram timings are properly configured) and use 3200mhz for the frequency. I disabled XMP and set it to 2933mhz, because that worked, and let it be.
I now enabled XMP and manually set my ram frequency to 2933mhz. But that’s my specific case. The thing is, if you have not done this yet; enable your XMP profile in your bios to make sure your memory uses the right timings.
You can read a bit more about it in my thread posted above ^^.
Edit: you can use any frequency where your ram runs stable by the way. Mine just happend to be @ 2933mhz…
