Hey everyone! I'm having some major issues with my system, and I'm hoping to get some insights before I start replacing parts. My Ryzen 5800X3D is getting stuck at only 573 MHz due to an alarming 1,650% Power Reporting Deviation on my ASUS ROG Crosshair VIII Formula motherboard. This is causing my system to freeze up and display a "Detect HDD" message—even when there are no hard drives connected.
Here's a rundown of my setup:
- **CPU:** AMD Ryzen 7 5800X3D
- **Motherboard:** ASUS ROG Crosshair VIII Formula (BIOS 5302)
- **GPU:** ASUS ROG RTX 4080
- **PSU:** ASUS ROG Thor 1200W
- **RAM:** G.Skill TridentZ Royal 64GB 3600MHz (2x32GB)
- **Storage:** 2x Samsung 980 Pro 1TB, 1x Kingston A400 SSD
- **Cooling:** ROG Ryujin II 360
The issues include extreme slowdowns where the CPU slows to 573.4 MHz, showing a power reporting deviation around 1,650%. Restarting the system doesn't help, and sometimes I experience complete lockups displaying Q-Code AA or Code 30. I've done a fresh Windows install and tried various BIOS settings and cable replacements, but the problem persists.
The issue seems inconsistent; some days the PC runs fine, while other days it crashes multiple times. I'm starting to wonder if my motherboard is the culprit. Can anyone offer any advice or insight before I consider a replacement?

Thanks for those tips! I applied the -2500 offset and during the Cinebench test, the reporting stayed at 96.5%. It's around 40-70% at idle now. So it looks like that helped a bit!
You might want to check your AIO cooler to rule it out. Even though your CPU temperature is around 40°C, the low clock speed could indicate it's not cooling efficiently. Make sure the pump is plugged in and working and check the RPM in the BIOS. Feel the tubes; one should be warm and the other cold.
The power reporting deviation you're seeing means your CPU thinks it's receiving 16.5 times more EDC, TDC, and PPT than AMD recommends. In the ASUS BIOS, you can adjust a setting called core current telemetry, which is what HWINFO64 uses to report those values. Try setting it to a negative offset, starting with -2500, and then run a Cinebench R15 stress test. You want to keep the reporting in the 90%-110% range. If that doesn't help, your motherboard sensors might be malfunctioning.
