Hi!
I have 2 modules G.skill f4-3000c15d-8gvgb (2x8Gb).
I know that this memory is not in the list of QVL, but it runs on a regular 2133MHz. The site G.skill indicated that it was tested for 3000 (power 1.35V), but this is for Intel.
On BIOS version 5.1, I was able to get stable work on the 2733. Everything above, after starting Windows, led to crash - a black screen (the higher the frequency the faster the system crash).
But after updating to 5.5, stable work is only on 2666.
I thought that with the update there will be an improvement in the work, and then it became even worse.
Should I need increase DRAM voltage or roll back BIOS?

I did some experiments.
1. At 3000 MHz, Memtest86 does not find errors.
2. In safe mode, everything works fine.
3. If I uninstall the AMD Vega driver, it still works in normal mode.
4. As soon as I install the driver, after reboot after a few seconds the screen turns black.
As far as I understand, this is some kind of bug with drivers.
