Considering my motherboard might be failing... (VIDEO)
My 5900X model from March 2022 is operating smoothly—except for a couple of issues: occasional POST failures or missing video at startup. I’ve confirmed these happen only a handful of times, usually after a cold boot, though they seem to increase recently. It never overheats or stalls under load. In BeamNG.drive, I can spawn and defeat thirty vehicles in rapid succession without any problems, and it behaves well in American Truck Simulator, with just minor frame delays. I’ve tested all standard fixes, so I suspect the problem isn’t BIOS-related, CPU instability, RAM faults, display glitches, or cable issues. Another curious sign is that the display sometimes misreads signal type and resolution, which initially led me to assume a GPU problem. There’s also a pattern where the motherboard and GPU Aura change colors when the machine is off—unless the PSU switch is disabled. I only noticed an orange debug LED today, which I identified as DRAM. Watching it light up during boot gives strong clues the RAM is failing.
Specifications: Ryzen 5900X (PBO enabled/disabled), Asus TUF Gaming B550 PLUS (ready for 5000GB, booted into BIOS immediately), Asus KO RTX3060ti-8GB-OC (with and without OC), Crucial Ballistix DDR4-3200 (DOCP supported), WD Blue SN570 1TB M.2, WD Black 6TB HDD, Corsair iCUE Commander Core XT, Corsair 4000X case, Corsair SP120 fans (3x), Corsair LL120 fans (3x), Corsair RM850x PSU, thermal paste on XT150.
I’ve tried reseating RAM, GPU, and all cables—temporarily fixed or thought it was resolved. I swapped the HDMI cable, moved the M.2 drive, relocated the GPU, changed the display cable, and even removed the PSU rocker switch. Each time I saw an orange debug LED, it pointed to DRAM. During testing, the fans turned through blue, red, white, and green, then orange, red, white, green—clearly a RAM issue.
I’ve also run MemTest86 on each RAM stick separately; both passed without error. The problem appears to be with the motherboard, possibly due to a shared component that failed after initial assembly.
Have you explored another BIOS version? I've noticed certain revisions on AMD boards can cause retrain stability problems. Memory failures sometimes lead to GPU error codes, though this isn't common. My X570 Master has experienced random 4F code errors during boot, even with limited RAM. The fix involved removing the CMOS battery for ten minutes, reinserting it, and restarting the system. I'm unsure if the PSU was on initially, so test both scenarios to find what works. It's a simple solution with minimal risk, making it worth trying before updating the BIOS.
Yes, this occurs. The system may run accurately and pass memory tests, yet it often becomes unstable under normal conditions and fails after the first reboot.
Yeah, I'd leave it out for a little bit longer (again, my board was 10 minutes+), but that's about the only other thing I can think of to try and fix it. If that doesn't fix it, contact ASUS.
