: 5GHz overclock at 70°C?
: 5GHz overclock at 70°C?
It's not too bad, I've never done overclocking before.
I just pushed my 7700K to 5GHZ across all cores at 1.32 volts. The Intel Extreme Utility stress test is running now and it's holding steady between 70-73 degrees, which is only a few degrees warmer than when I ran it at stock speed. Is this actually achievable? Could my system be underreporting the temperatures? It would have stopped by now, wouldn't it?
Relevant specs:
i7 7700K, delidded (Conductonaut liquid metal, Thermal Grizzly Kryonaut paste)
Noctua NH-D15 cooler
5 be quiet Silent wings 2 fans (4 140mm intake, 1 120mm exhaust)
2 silent wings 3 top exhaust (previously connected to a radiator)
Be quiet Silent base 801 with airflow front panel
Also, if this really reflects the thermal margin I have, how much higher can the chip go? SiliconLottery claims the best chips can reach 5.3GHZ!
Be cautious about these assertions, but let's try it.
Apply a standard moderate load using tools like CPU-Z or benchmarks such as 'stress CPU'.
Observe the temperature readings.
My 7700K running at 4.7 GHz stays around 60°C under these settings—though that 300 MHz gap still matters.
Just because temperatures remain stable doesn't guarantee it will be reliable or have extra headroom...
Test Prime95/small FFTs (AVX/AVX2 off) for 15 minutes without any issues.
