I have my 9900k over clocked to 5.0 across all cores. I used a guide I found on you tube
I have overclocked before with success.
The errors im getting are
A corrected hardware error has occurred
Reported by componet Processor core
The embedded controller EC returned data when none was requested. The bios might be trying to access the EC without sychronizing with the operating system.
I have never blue screened. I did have a crash that my video drivers stopped working but wouldnt that be my overclock on my gpu ?
