Hey everyone! I'm encountering a frustrating stability issue with my setup and could really use your advice. Here's the rundown: I'm using a Ryzen 9 9900X processor on an ASUS TUF Gaming B850-Plus WiFi motherboard with Lexar Thor DDR5-6000 RAM. The system runs excellently in single channel mode with one stick of RAM for over 40 hours without any issues, but once I switch to dual channel with both sticks, I get random black screens or hangs after about 12 hours.
Sometimes I see MEMORY_MANAGEMENT errors, and the system just sort of cuts out with an odd sound before resetting itself. I've already tried various troubleshooting steps like updating the BIOS, changing DRAM frequencies, and adjusting voltages, but nothing seems to resolve the issue in dual channel. Notably, I've tested my brother's higher speed RAM in the same configuration and it seems to work fine.
I'm curious if this is a known problem with the B850 chipset and DDR5-6000 RAM on Ryzen 9000 series CPUs. Should I consider RMAing my RAM, or do you think the motherboard might be the culprit? Has anyone with a similar setup found stability with these specs? Any help would be greatly appreciated!

I've had success running a similar setup with 6000 MHz RAM, but the key was to manually configure the timings and voltages. It might take some experimenting, but if you haven’t tried yet, set the timings to match what’s recommended for your RAM and adjust the voltage accordingly. Sometimes that extra bit of tweaking can make all the difference!
It sounds like you're dealing with a classic dual channel RAM issue, and it's been reported that some configurations with the Ryzen 9000 series and B850 boards can be finicky, particularly with certain RAM types. Before making any drastic moves like RMAing your parts, I suggest collecting those minidump files and analyzing them. They can point to whether it’s the RAM or something else entirely.
I had a similar problem that turned out to be alignment with the motherboard's supported RAM types. Your Lexar Thor DDR5-6000 isn't listed on the ASUS QVL, so it might be worth trying RAM that is known to work well with your board. In my case, switching to a different brand that was on the QVL resolved my issues. Might be worth a shot!
