I'm facing an issue with my Ryzen 7 5700X setup that I think might be related to memory or the integrated memory controller. Here are my specs:
- CPU: Ryzen 7 5700X
- Motherboard: MSI B450 Gaming Plus MAX with the latest BIOS
- RAM: Corsair Vengeance LPX 32GB (2x16GB) DDR4 3200 CL16
- OS: Fresh install of Windows 10/11.
Here's the problem: my system crashes when using the RAM at 3200 MHz. I've noticed that games, particularly Battlefield, cause black screens on my monitors and result in game crashes. While I can boot into Windows with the RAM at 3200 MHz, heavy gaming quickly leads to instability. However, when I run the RAM at 3000 MHz, everything is completely stable.
I've tried enabling XMP, manually setting DRAM speed, and tweaking voltages, but no luck. The RAM crashes under gaming loads even when I increase the SoC and DRAM voltage. I've also reset the BIOS and tried various configurations. It seems that my memory controller or Infinity Fabric prefers a more conservative setting like 3000MHz. I'm curious if this is a known limitation with the Ryzen 5000 series plus 2x16GB RAM on a B450 board, and if there are any specific BIOS settings I should double-check. Is 3000MHz the safe bet here?

It sounds like there might be an issue with the memory controller on your CPU. Some Ryzen CPUs handle 3200MHz RAM perfectly, while others struggle with it, especially with 32GB configurations. The RAM itself could also be a factor, particularly if it uses less reliable Micron chips instead of SK Hynix. Double-check the model numbers printed on the modules to see what you're working with.
Also, make sure you have the RAM installed in the correct slots, typically A2 and B2 for dual channel, and that you're running the latest BIOS version.
I had similar crashes at 3200MHz. For me, it was stable mostly but during gaming, it would crash randomly. I found that lowering the speed to 3000MHz made a significant difference, stabilizing my system effectively. It might just be the realistic setting to use with your current hardware.
