The PC fails to cold boot following an overclocking attempt.
Sorry for the poor English.
My system specifications are as follows: Gigabyte Z97X gaming 5, Corsair vengeance 8GB x2 at 1600MHz, I7 4790k, MSI GTX 980ti 6G, PSU Corsair HX850i.
I went to BIOS to attempt overclocking, adjusting the multiplier from 4.4 GHz to 4.6 GHz and V.core to 1.250. Then I used IBT with 30 loops and 10GB RAM to stress the CPU. There were no BSOD crashes, and I played CPU-intensive games like AC Unity, GTA V, and Syndicate. Everything seemed normal. The CPU temperature reached 75°C using Hyper 212.
After that, I turned off the CPU for a while. About two hours later, I restarted the PC, but it still wouldn’t turn on. The PSU made a normal click sound, but the PC didn’t enter POST, and neither did the fan or LED chassis fans.
Eventually, after switching to a different power outlet, the PC turned on, but if I turned it off again, the issue persisted. So I think I need to change the power supply. I decided to reset the multiplier back to 4.4GHz and V.core to 1.2, and everything worked again. No more problems.
Do you know what happened to my CPU or motherboard while I tried overclocking? Any help would be appreciated.
Then just stick to the 4.4ghz setting, since you're having issues at 4.6ghz. Also, the performance difference between 4.4ghz and 4.6ghz isn't significant. Or consider increasing the core voltage slightly, such as 1.26V or 1.27V, because if your chip can boot at 4.6 GHz with 1.25 V, it indicates you're using a decent chip.
