Hello
So i tried overclocking my Intel core i5 4670k to 4.2 ghz with arround 1.200 core voltage and the ring ratio to 4.1 ghz and with 1.175 v. it was fine.. so i thought..
I ran prime 95 for like 10 minutes and no errors or BSOD, so i closed Prime95 but 30 minutes later a bsod, so i went back into the bios and changed it all back to auto, because i thought i undervolted the cpu. But when i run cpu-id it says that my CPU is using 1.225 v at stock? is that a bad chip?
Motherboard: MSI Z87 g45 gaming with latest BIOS update.
