ASUS X570-E equipped with 5900X QCODE 00
Hey there! It looks like you're experiencing a QCODE 00 error on your motherboard despite updating BIOS to version 3001. You removed the rest of the components except the CPU, power cables, and the CPU itself, but the issue persists. Your old 2700X was working fine, so it might be a problem with the 5900X. Consider checking if the motherboard is compatible with your CPU model or reaching out to the manufacturer for support.
Examine the CPU and look for bent or missing pins. Verify the EPS power connector is connected properly (top left corner of the motherboard). Assess your PSU wattage—maybe it’s insufficient. The error typically points to the CPU. If you have another CPU to test, you can eliminate the motherboard issue. Consider why you used the flashback feature during BIOS flashing; did the system fail to start? Generally, X570 boards released after August should boot Zen 3 at least into BIOS.
The CPU seems fine after initial checks. All EPS connectors are securely plugged in the 12 pins. With an 850W gold PSU, the power supply isn’t likely the issue. I didn’t realize the August update was relevant until after installing the motherboard. I tried a 2700W model but had no success. It might be a problem with the BIOS. I’m considering returning the motherboard to Amazon and getting a new one.
