Bad CPU OC
Bad CPU OC
A few days back, while overclocking my CPU, everything was functioning properly. I accessed the BIOS to lower the core voltage and restarted the system. After the restart, I received an error message saying "CPU Over Voltage Detected." I checked the BIOS settings and found that the core voltage was at 1.7v. Since I'm using a 8700k, I was concerned it might exceed the safe limit of 1.37v, especially given the high temperatures. I wasn't sure if my temperatures were normal or not, but after resetting the CMOS to verify everything was back to default, I tried running some games again.
It appears that my games are crashing after about 10-15 minutes, with the same issues occurring for each game. The ones that crash are PUBG and Tarkov; I'm not sure about others. The games freeze, but I can still hear audio and notice it reacts to keyboard inputs. I also observed instability in Windows, such as the desktop freezing or becoming unresponsive temporarily. There are also micro freezes when launching programs.
My main concern is whether a poor CPU overclock could be causing these problems and if it might have damaged other components. I performed checks on my RAM and hard disk, both showing 100% health. I was able to run CPU and GPU stress tests without any issues.
I reset the CMOS again today and noticed Windows performance improved somewhat (though not completely), but games continued to crash with minor frame drops and micro freezes. I've tried all the tests I could think of, but I would appreciate a second opinion on whether other parts besides RAM and M.2 drives might be affected. If I don't find any solutions here, I might have to replace my CPU.
It's entirely feasible the CPU was affected. Under typical overvolt conditions, heat accumulation can lead to damage gradually, but such a situation might result in immediate harm. Additionally, since the memory controller resides on the CPU, this component could also be compromised. You may want to try a budget low-end CPU before investing in a new 8700K.

It's entirely possible the CPU was damaged. On normal overvolts heat buildup does damage over time but a setting like that could cause immediate harm. Also the memory controller is on the CPU so that part of it may be bad. You might get a cheap low end CPU to test with before shelling out for a new 8700K.
I wasn't thorough enough, and tested heaven benchmark again and it crashed, every time after about 1 minute or two. Prime95 would not crash, although temps were higher than normal. This leads me to believe that my card was possibly damaged during a waterblock installation. I just build my custom loop 4 days ago. Either way, I ordered a bew 8700k and will return it if the problem persists. I hope it doesn't because this card is $1300.
