Hello. I encountered a problem where my computer fails to POST when there are multiple RAM sticks installed in the DIMM_B2 slot. This has happened before, requiring me to return the product for repair. I’ve tried several fixes like clearing CMOS, re-seating the CPU, updating the BIOS from 1415 to 1516, and rearranging RAM positions to identify issues. The key finding is that using just one stick in either A1 or A2 triggers a Q-Code 15, preventing the system from booting. Waiting 10-20 minutes after inserting RAM doesn’t resolve the issue. Placing two or more sticks in any slot also causes Q-Code 15 and POST failure. My current setup includes: Windows 11 Home Edition 64-bit, ASUS ROG Crosshair x670E HERO (BIOS 1516), AMD Ryzen 9 7950X with four x4 Thermaltake TOUGHRAM XG 16 GB at 6000MHz (experiencing issues at EXPO 1 and stock speeds), ASUS ROG Strix NVidia GeForce RTX 3080 OC Edition, Samsung 980 SSD NVMe M.2 1TB for the boot drive, a Samsung 870 EVO 2.5 Inch internal SATA III SSD 2TB for storage, and an ASUS ROG Strix 1000W AORUS Waterforce x360 AIO.

No, I don’t use old BIOS files. They’re outdated and can cause instability.

I got the first motherboard and CPU in April, especially after concerns about burned CPUs arose. After reinserting the CPU, I checked it and saw nothing unusual. I also reduced the voltages to minimize the chance of burning the CPU. Around the time RAM problems started, voltages went back to their normal settings.
