Greetings and a happy new year to every one of you.
After having a lot of issues with my I7 7700k chip the past year I decided to dive in again on the overclocking part of it to make use of the unlocked feature.
Around a year ago I had a lot of trouble even getting it to run on default clocks. My system would lock up a lot, the temperatures were horrendous on air - talking easily going into stable 90°C+ and dipping to the 100°C mark. I sent in the whole new setup twice for RMA reasons and got it back both times saying no issues found. Undervolting wasn't possible at all. Even an offset of -0.010V would cause locking up.
After that I went ahead and delidded, dropping my temps under default clock to stable 60-65 at load - the thermal compound unterneath the IHS wasn't even connected to it. The heat pretty much was transferred through the air inside.
For the stability I had to resort to auto voltage and the most aggressive LLC setting of my mainboard which is LLC1.
Ever since the system runs smooth on the following specs:
I7 7700k | 4200mhz default clock | no multi core enhancement | auto vcore around 1.280V max
4x4GB DDR 4 running on XMP with 3200mhz
ASRock Z270 gaming K4
For the overclocking part I can't manage to get near 4.800mhz cpu freq / 4200mhz cache, even on 1.360VCore the system locks up in less than 5 minutes of benchmarking or stress testing. Even when opening for example a browser it will happen. The temperatures while it manages to run are around 75°C, sometimes going up to 80°C under load which I expected for being on air cooling only.
Seeing different results from others reaching goals of 4.8-5 on lower VCores, some way below the 1.360 I went up to gets me curious if I just lost the silicon lottery or if there may be other culprits involved. Maybe I need to push more volts but I'd rather have some input of more experienced people before frying up anything.
So long, thanks for looking into my issue and let me know if you need any additional info could provide.
