Overclocking my i5 6600k
Overclocking my i5 6600k
Right now I'm operating at 4.7 ghz with a voltage of 1.38 and temperatures below 75°C. I'm curious if increasing the output could push me further.
Perfect overclock achieved, very appealing design indicates a solid chip.
Chugalug is correct, stay below 1.4v as the limit for longevity and stability.
Ensure hardware monitoring confirms actual draw around 1.38, avoid peaks or spikes.
Skylake on certain boards may briefly exceed this threshold due to voltage fluctuations; verify your unit doesn’t surpass it significantly.
Stress testing without tools like Prime95 is advisable, and observing the hardware over several hours can reveal any unexpected voltage surges above the target.
Theoretically you could overclock it to any number, but the amount of required voltage spikes around the 4.6 mark with the 6600k.
I wouldn't go above 1.40v as this is the stage at which this model of CPU would begin to suffer from a lowered lifespan.
You have a great higher than average overclock as it is, I wouldn't be worried!
Overclock perfectly, the design is impressive—it clearly indicates a solid chip.
Chugalug has a point, stick to 1.4v as the safe limit for longevity; keep an eye on hardware to ensure it stays around 1.38 and avoid any peaks or spikes.
Some motherboards might show slight voltage fluctuations, like a Skylake chip occasionally adding a brief spike.
Be cautious—monitoring over a few hours can reveal if the voltage ever exceeds the recommended 1.4v.
I've reached a maximum of 1.387, currently holding around 1.376.
It isn't specified in the provided text why Prime95 should not be used with a Skylake (6600K) chip.
Prime95 has been demonstrated to put the CPU under excessive stress, leading to instability or potential damage in certain situations. I want to make it clear about this in terms of CPU lifespan. Raising the voltage to 1.5v doesn’t guarantee a four-year lifespan; it simply indicates that the power delivery has surpassed Intel’s recommended limits. At that point, the lifespan may decrease slightly—perhaps from 12 years to 10—but it’s unlikely your CPU will fail completely before then. I’ve overclocked for years without any issues, and my 2600k is still functioning well in an older setup since 2011.
Chugalug_ has mentioned that Prime95 can put the CPU under excessive strain, leading to instability or damage in certain situations. I think it’s important to re-examine my previous remarks about CPU durability. Putting the voltage at 1.5v doesn’t guarantee a lifespan of only four years; it simply indicates that the power level has surpassed Intel’s suggested limits. This might shorten the life by a few years, possibly reducing it from 12 to 10 years, though it’s unlikely your CPU will fail completely before then. Personally, I haven’t seen any failure in my own setup, and I’ve been pushing overclocking for years. My 2600k is still working well on my older system, which has been running since 2011.
Hello,
I recently assembled a new rig about a week ago. My previous one stopped working, and I’m still trying to figure out why. I tested the PSU using a tester (not under load), and everything looked normal [Corsair GS700]. One day I encountered a BSOD and the machine shut down completely. After restarting, it worked again, but the next day it failed once more. I never accessed the BIOS afterward. The fans would spin up, and the LED indicators on my Gigabyte motherboard would flash, then the system would power off repeatedly—an endless cycle of start and stop.
I suspect either the motherboard or the processor failed. The chip was a Wolfdale 8400, which performed well for nearly nine years. The same went for the Gigabyte GA-EP45-UD3P board and G.Skill RAM. It might have simply given up after being overclocked to 3.9ghz for more than eight years.
I had limited options for troubleshooting—no spare processor or PSU, no extra memory, no POST card, etc. I tried my best, but the outcome remains unclear. The BSOD mentioned a checksum error and that the system powered down to protect itself from hardware damage. I’m curious about what exactly failed.
My new setup is decent, using an MSI Z170A M5 Gaming board with an Intel 6600K and 16MB of Crucial Ballistic RAM.
What tools should I use to stress-test the Skylake CPU? I have Intel Burntest, Intel XTU, and a few reliable monitoring programs.
Thanks,
