I see the problem, and given that my board is a Gigabyte Aorus ultra gaming X470 you have me wondering if it's my board that caused my issues as well.
My SniperX RAM does work at XMP settings, but the PC was prone to an occasional crash particularly in far cry 5 until I set the RAM to 2933. A couple of BIOS updates helped as well and it's been stable for 2 months now.
Still if testing with Ryzen does become an option I would appreciate and I'm sure I'm not alone in that. One of the more daunting aspects in going for Ryzen is knowing what RAM you can use. Even if all that's said is it works at default and XMP settings on board X.
For me personally of course I'd have loved the gigabyte board to have been used because it's the closest to mine, and the world exists for my benefit right? 😛
