I have an Intel i7-13700K CPU with 32GB of RAM running at 6400MHz with XMP enabled. I've heard that I might experience stability issues because Intel claims the CPU only officially supports RAM speeds up to 5600MHz. However, my motherboard's QVL states that my setup is compatible. Should I lower the speed to 5600MHz for stability? If that's the case, how do I change the settings? Do I need to tweak other RAM timings or just keep XMP enabled? Also, should I be using XMP 1 or 2?

If your setup is stable at 6400MHz, there's no need to drop it down. It’s pretty rare to have issues at that speed with two DIMMs. If you’re experiencing crashes, it might not be the RAM causing it. But if you want to try lowering it to 5600MHz for peace of mind, go ahead and tweak it.
To lower your RAM speed, just enable XMP which auto-configures your settings. Then, change the DRAM Frequency from 6400 to 5600MHz in your BIOS. Save and exit. If you want to experiment, you could try stepping it up to 5700, 5800, or higher to see if it remains stable.
Before making any changes, I recommend updating your BIOS, as there are known issues with this CPU that could affect performance. If your RAM is passing tests, don’t just assume it’s the culprit. If you still want to drop the speed, keep XMP enabled and try setting it to 6000MHz first. You paid for that speed, so don’t give it up without reason!
