6700k Overclock Guidance
6700k Overclock Guidance
Hey there, I just got an i7 6700k and a Corsair H100i V2. I wasn’t sure where to begin with overclocking.
Right now I’ve set my 6700k to 4.5GHz @1.28V, it’s stable during a 15-minute realbench test (and probably will last longer without problems). The temperatures are as follows:
(minimum temps = idle after 15 minutes)
I’m new to CPU overclocking, so I’m wondering if this is okay and whether I should tweak the core multiplier and voltage.
Also, am I doing a good job with the current GHz/voltage?
And overall, are these temperatures acceptable? Since it was a stress test, I expect them to be lower than gaming levels.
If you have any questions, feel free to ask—I’m using Arctic MX-4 thermal paste.
Thanks!
I also have an i7 6700K and a Dark Rock Pro 3 cooler. I recommend using Offset Voltage (Adaptive Voltage) for overclocking instead of fixed voltage or automatic motherboard OC settings. This allows the CPU voltage to adjust when the load decreases, which also helps save power.
For example: I’m running my i7 6700K at 4.6ghz (4.56ghz in Task Manager) with a +85mV offset. My CPU reaches a maximum of 1.344v. Under heavy stress, the temperature can reach up to 74°C. I’m also using Corsair Veangeance LPX 3000mhz at 2933mhz, increasing VCSSA and VCCIO, which required a 4.7ghz OC. At that setting, the CPU needed only 1.39v, causing temperatures to rise more than necessary—about 10°C higher than desired.
To note, every CPU...
Hi there, I just purchased an i7 6700k along with a Corsair H100i V2 and wasn’t entirely clear about where to begin with overclocking. Right now my 6700k is running at 4.5GHz @1.28 Volts, it’s stable during a 15-minute realbench stress test (it could probably last longer without problems), and the temperatures are as follows: minimum idle temps after 15 minutes. Since this is my first attempt overclocking any CPU, I’m wondering if these settings are acceptable or if I should be tweaking the core multiplier and voltage. I also want to know if the current GHz/voltage combination is suitable. Are these temperatures reasonable for a stress test? Also, I’m using Arctic MX-4 thermal paste. Please let me know if you can address any of my questions! Although the chip itself isn’t great, the cooling performance is impressive. You might try pushing it higher until you hit around 75–80°C max. Also, avoid trying to drop the core voltage to 1.4V or lower. I’m a bit jealous because my i7 4790k @ 4.5Ghz already reached 80°C on an ASUS Realbench V2.54 during an 8-hour stress test with a Noctua NH D15 S. Would you consider trading?
I also possess an i7 6700K along with a Dark Rock Pro 3 CPU cooler. It is highly recommended to perform overclocking using Offset Voltage (Adaptive Voltage) rather than fixed voltage or motherboard Auto OC settings. This allows the CPU voltage to adjust when the workload decreases, which also helps in saving power usage.
For example: I am running my i7 6700K at 4.6ghz (4.56ghz in Task Manager) with a +85mV voltage offset. My CPU reaches a maximum of 1.344v. Under extended stress testing, the temperature peaks at 74°C. Additionally, I am using a Corsair Veangeance LPX 3000mhz at 2933mhz, increasing VCSSA and VCCIO, which required a 4.7ghz OC. At that setting, my CPU needed 1.39v, causing temperatures to rise significantly above the necessary level—about 10°C higher than desired.
Please remember, every CPU behaves differently. It’s advisable to discover your optimal sweet spot. You might be able to achieve 4.7ghz with a lower voltage than mine. Your temperatures are acceptable, but it’s wise to run a test for at least 30 minutes to confirm the maximum temperature.
In summary, consider applying an offset voltage and observe the achievable frequency at stable temperatures.
Yes, setting the cpucore/gt voltage mode to adaptive+offset in the BIOS should work.
