What is CPU-VCORE-LOW?
Low CPU supply voltage is a high-severity processor (CPU) issue. Powering the processor below the minimum causes instability and crashes. Common triggers are weak resource, damaged VRM and bad EPS connector. See the troubleshooting steps below for the fix.
Common Causes
- Weak resource
- Damaged VRM
- Bad EPS connector
Step-by-Step Fix Guide
-
1
Check the 8pin EPS connector
Check the 8pin EPS connector resolves the majority of CPU-VCORE-LOW cases on its own, making it the logical starting point.
-
2
Test with a stronger PSU
A second occurrence often means a less common cpu instability cause is at play, which later steps address.
-
3
Check the VRM temperature
"Check the VRM temperature" is the next step worth ruling out for CPU-VCORE-LOW.

Frequently Asked Questions
CPU-VCORE-LOW is most often triggered by weak resource. Other reports point to damaged VRM and bad EPS connector as contributing factors.
Try "Check the 8pin EPS connector" first — it resolves most CPU-VCORE-LOW cases on its own. Only work through the rest of the guide above if it comes back.
CPU-VCORE-LOW is a high-severity error. It won't damage your PC instantly, but repeated occurrences usually point to a deeper problem worth addressing soon.
You shouldn't need to. Work through the guide above first — a reinstall is only worth considering if none of those steps help.
Not necessarily. CPU-VCORE-LOW can be triggered by software and driver issues, overclocking instability, or BIOS misconfigurations — not just hardware failure. Run through the diagnostic steps above before concluding the processor itself is defective.
