Hey, I see you're using a Ryzen 7 2700X with 32GB of Vengeance RGB (4x8GB) on an X470 Pro Carbon board. When trying to pick XMP profiles 1 or 2, the system doesn't boot and resets RAM to the default 2666Mhz. You managed to set it to 3333Mhz in profile 1 with two sticks, but now it's stuck at the rated speed in profile 2. Anyone have any tips? You're also on the latest BIOS update.

Your chip is designed for speeds of "up to" 2933 MHz. Exceeding that isn't assured. Your particular CPU might simply not be able to push past that limit when all four DIMM slots are filled. Consider testing with just the two new modules in the same setup as before. https://www.amd.com/en/product/7656 https://en.wikichip.org/wiki/amd/ryzen_7/2700x A solid AM4 board works well—just drop a Ryzen 5000 series into it for optimal RAM performance and noticeable gains in processing power.

Adjusted to 2933, it caused instability in the overclock. Disabling it resolved the issue.

Older Ryzens tend to be more selective about overclocking RAM. Using four sticks instead of two adds extra complexity for the CPU's memory controller. You might succeed by adjusting clocks and voltages manually. On the motherboard's support page, there’s no RAM listed that exceeds 2666 MHz (https://www.msi.com/Motherboard/X470-GAM...upport#mem)
