Is my overclock safe
Is my overclock safe
I've just pushed my i7 4790k beyond its limits for the first time. The CPU looks clean with liquid metal between the dye and IHS. My overclock is stable at 4.7 ghz with a core voltage of 1.250. Turbo boost is on, EIST is active, enhanced turbo is off, and nothing else changed. Task manager shows 5.7 ghz under load, which is higher than the reported frequency. My temps stay around 65 degrees. Is this normal?
Continue using the 4.6/1.250V setting, as it might be a restriction of the motherboard. It's worth noting how much overclocking the additional 100-200mhz could be risky today, especially since getting replacement parts would be costly or hard to find due to its age. At 65°C under full load at that voltage, it remains safe and should last for a while.
Ignore the speed task manager reports as they seem inaccurate. Your voltage and temperatures are safe, making it suitable for overclocking or delaying. However, is this a good approach with a 65C through a game or CPU benchmark? If yes, run Prime95 Small FFT with AVX disabled and report the temperature. As long as it stays below 85°C during stress testing (or under 80°C while gaming), everything should be okay.
So 65C at 30 mins is acceptable, but if you're using air cooling you can stop, whereas with an AIO you might want to test for an hour.
You might be able to push it a bit more with overclocking if you wish.
I cooled using an aio, finished the full hour with a max temp of 65 degrees. It looks stable. I’d try 4.7 ghz or 4.8, but it boots directly to the blue screen.
Continue using the 4.6/1.250V setting, as it might be a constraint of the motherboard. It's intriguing to observe how much overclocking the additional 100-200mhz could be risky today, especially since locating replacement parts would be costly or hard to find due to its age. At 65°C under full load at that voltage, it remains safe and should function for a long time.
