I recently upgraded my PC by adding two 8GB sticks of RAM to my existing setup, giving me a total of 32GB of DDR4 RAM. The new RAM is in slots 1 and 3, while the old RAM is in slots 2 and 4. Since making this change, my computer has been freezing and I've been experiencing Blue Screen of Death (BSOD) errors, specifically one with the stop code PFN_LIST_CORRUPT (0x4E). I've tried troubleshooting with various tools but haven't had much luck. My RAM speed is set to 2400, and I'm using the auto setting on the AI Overclock tuner, which I thought would help with any XMP issues. I have an ASUS RoG Motherboard. Can anyone share some tips or do you think I need to take my PC to a professional for help?

Mixing different memory kits can often lead to issues like you're experiencing. It's usually best to stick with a single kit that’s certified to work together. If you can, try running MemTest86 to check for any errors in your RAM. You might also need to disable XMP, as that setting is often optimized for only two sticks. Also, auto overclock settings might not always be stable, so it’s worth considering switching that off.
It's also a good idea to check your CPU model and see if you're running the latest BIOS update for your motherboard. The Intel Core i7-9700K should be fine, but sometimes, BIOS updates can fix memory compatibility and stability issues. What version are you currently on?
