Yesterday upgraded my CPU from an i5-4690 to an i9-10850k and also got a new Motherboard (ASRock Z490 Phantom Gaming 4/ac)
I don't know whether it matters or not, but I didn't setup my PC from new, so the windows installation and all the data from my old PC are still on my harddrive.
After booting the system for the first time, I wanted to check the performance of my new i9-10850k and wanted to test it in Cinebench R23. But when I started the Multi-Core test the PC instantly shutsdown and restarts after a couple of seconds.
Next I tested the Benchmark of UserBenchMark because maybe Cinebench is just incompatible with the i9-10850k or something. This Benchmark started with 1 Core used more and more cores after time. It was still working with 8 cores but then it jumped up to 64 cores and the PC crashed. So the limit is somewhere between 8 and 10 cores (because this CPU has 10 cores).
Then I wanted to see whether this also happens when playing CPU-Heavy games like Cyberpunk, it worked. But maybe this wasn't hard enough for the CPU.
Since then I have been playing around in the BIOS, changing voltage settings, changing the number of activated cores, CPU Frequency Ratio, etc. and tested everything in Cinebench. I looked up some Overclocking guides for this CPU with the same Motherboard, to see what settings work out for others but even with those settings the PC crashed when starting the benchmark.
So, I learned a couple of things:
- The PC only crashes at a CPU Frequency of 4.7Ghz (sometimes 4.7GHz worked out in Cinebench but 4.8GHz is definetly the limit when using all 10 cores)
- Using less cores worked out sometimes and sometimes it still crashed.
- I don't think it crashes because of the temperature, because this happens just too fast, i don't think the temperature couldn't rise that fast. Also when using some settings (that I sadly don't remember) the CPU was at 105°C during the Benchmark (before the motherboard automatically regulated the Mhz so the CPU doesn't burn down).
- I also don't think this happens due to my Power-Supply-Unit. It can handle up to 600 watts, that should be enough, shouldn't it?
For now i went back to the normal settings and just don't start any benchmarks, but I don't want to live in fear of a sudden PC crash when I am working or gaming on this PC.
So do you have any ideas what the reason for this is? My guesses are that the CPU is broken, my RAM is broken, my CPU-Fan is too weak or the PSU is too weak (last 2 should be unlikely)
