CPU Over Voltage Error
CPU Over Voltage Error
I recently assembled a new PC but encountered a "CPU Over Voltage Error" during boot, though it still boots into Windows. The graphics card isn't recognized, yet the system powers on with fans and lights. I attempted to flash the BIOS, but the motherboard took over for seven hours without an error, allowing access to the BIOS interface.
Key details:
- Voltage peaks at 1.705V.
- After 20 minutes of idle in BIOS, CPU temp hits 40°C and motherboard temp reaches 29°C.
- Motherboard has both 8-pin and 4-pin 12V connectors; the PSU only has an 8-pin, but the manual says the 4-pin isn't needed.
- Experiments include updating BIOS, updating Windows, removing and reinserting the CPU, and disabling turbo mode.
The CPU voltage is managed by the motherboard/CPU. Have you attempted adjusting it in the BIOS? The PSU will only provide 12V to the internal power supplies. Even if it deviates significantly from specifications, the VRMs should still manage the reduction.

Hey there, that's a bit confusing. Thanks for asking! (And yeah, the default voltage is still 1.7V.)
