1.2Voltage exceeds safe limits for 8600k at 4.4-4.5ghz
1.2Voltage exceeds safe limits for 8600k at 4.4-4.5ghz
I'm checking how my overclocking setup is doing. At 4.5ghz with 1.2volts, I'm unsure if it's too high, too low, or just right. The hyper 212 x turbo dual fan cooler keeps the temps stable, and my CPU stays under 60% even at full load. Is this a suitable setting?
How well you can operate at a 8600K depends largely on obtaining a suitable chip.
As of 3/22/2018
The percentage of I5-8600k chips that can handle an aggressive vcore of 1.4 or higher and remain delidded is:
4.9 – 96%
5.0 – 85%
5.1 – 66%
5.2 – 38%
5.3 – 13%
You’re doing well. No adjustments needed if you’re satisfied with 4.5.
Delidding helps lower chip temperatures, possibly by around 20°C.
Increasing the multiplier means the vcore must also rise to keep stability.
It’s the higher vcore that raises the temperature.
Keep an eye on your vcore using cpu-Z; excessive values can harm the processor.
1.4 is near the limit, I wouldn’t stress about 1.3.
Using adaptive voltage and speedstep will affect the multiplier and its related vcore.
There isn't a perfect balance because it varies with your cooling setup. As long as you're under 1.4v, it's fine.
1.2v works well for a 4.5ghz boost. If your temperatures stay below 80C, you might reach 4.8ghz with 1.25-1.29v.
There isn't a perfect balance because it varies with your cooling setup. As long as you're under 1.4v, you're fine. At 1.2v it's quite good for a 4.5ghz boost. If temperatures stay below 80C, you might reach 4.8ghz with 1.25-1.29v. I won't push it too far right now; I'm content at 4.5ghz and think adjusting to 1.19 or 1.18 could help stability.
It seems you'd like to confirm stability. For consistent results, I recommend running OCCT for approximately 8 to 10 hours with a large dataset.
TechyInAZ says it works well. Just confirm stability is solid. For my testing, I ran OCCT for about 8-10 hours with a big dataset. Then I played Fortnite and GTA at top settings for roughly an hour each, observing the voltage remained steady at 1.2 and stayed around 4.5ghz for most of the time, occasionally reaching 60.
If that's the only thing you do, it's a completely acceptable test. However, I'm not very confident it's fully stable.
For better results, I suggest running OCCT for about 8 to 10 hours, then performing memtest86 overnight to verify your memory.
I'll give it a shot tonight!

You’re managing well. No adjustments needed if you’re content with 4.5.

If you raise the multiplier, the vcore must also increase to keep stability.
It is the higher vcore that raises the temperature.

Around 1.4 is optimal, I wouldn’t stress about 1.3.
Using adaptive voltage and speedstep will reduce both multiplier and vcore when usage is low.
Many testers rely on AVX instructions, which are uncommon in gaming.
Such a stress test may reveal two lower multipliers than what’s achievable in real scenarios.
If you’re okay with occasional shutdowns, don’t worry too much about stability.
If that occurs, assume your overclock was too extreme, tweak it, and proceed.
On a stress test, 85°C seems reasonable; this is the default target for OCCT.
The CPU will automatically throttle or shut down if it senses dangerously high temperatures.
This threshold is roughly 100°C.
If your typical operating temperatures sit around 75°C, that’s acceptable.
