Is this temperature suitable for your current overclock, and can you increase it further?
Is this temperature suitable for your current overclock, and can you increase it further?
hey guys if you've pushed your i5-8600k to 4.6 and it still doesn't hit 70 during long gta sessions at full settings, are you okay to try 4.8? Your furmark 'cpu burner' shows it stays under 83°C.
When it comes to OC there's no recommended voltage, as every cpu responds differently. There were some i7-8700k that at stock showed 1.4v for stability, and some that were good with 1.2v. So the only recommendation is lower = better. How low that is depends entirely on your particular cpu. You might still be way above the lowest point, you'll have to start dropping by 0.05-0.08v and retesting until you loose stability, then bump back up 1 notch. Same goes for 4.8GHz or 5.0GHz.
Stability and temps are 2 different things. You are stable now, but have temp room for higher. You could get stable at 5.0GHz, but have totally unacceptable voltages and temps. It's a dance. And takes a while to dial in, possibly months. With stability testing...
Furmark CPU burner alone isn't optimal...
Stability of overclock voltage depends on workload: Cinebench R20
Use Open R20, go to File > Preferences > Minimum Test Duration.
Input an extremely high number (like 9999999999), click OK, then Run.
Execute for a minimum of one hour; the longer it runs, the better.
Ensure thermal stability with the CPU cooler by running Prime95 Small FFT with all AVX options turned off.
Cancel in Open P95, proceed to Advanced, and verify SUM(INPUTS) error checking.
Navigate to Options > Torture Test > Small FFTs.
Toggle all AVX options, then click OK.
Execute for 30 minutes to an hour.
What does 'nowhere near 70' refer to exactly? 61C or 69C? I'm planning to add another 100 MHz and check stability.
If you need something slightly less intense than Prime95 (as described earlier) but still more demanding than typical games, CPU-Z, benchmarking, or stress tests are quite sufficient for the temperature readings you're observing, with an extra 5°C added to it...
Alright so ive done all this and lowered my voltage to 1.25 at 4.8ghz and ive ran both tests at around an hour time with no single stability issue, my temps never went above 86.
Is this enough to say that this will be a stable overclock to run permanently?
And maybe if needed i could go upto 5 ghz, and if i do want to do that which voltage is recommended?
Im using a liquid cooled 240mm 2 fan cpu cooler on my cpu and my cpu is the i5-8600k.
When discussing OC settings, there isn't a standard voltage to follow since each CPU behaves differently. Some i7-8700k models showed 1.4v for stability at stock, while others performed well with 1.2v. The best advice is to use a lower voltage, as it generally improves stability. The exact amount varies based on your specific CPU model. You might still be operating well above the minimum threshold, so gradually reduce the voltage by 0.05-0.08v and re-test until stability is achieved, then increase it slightly. The same applies to higher clock speeds like 4.8GHz or 5.0GHz. Stability and temperature are separate concerns—your system can be stable at certain frequencies but may struggle with extreme voltages or high temps. It’s a process that requires patience, often taking several months to fine-tune.
