Safe overclocking tips for i7 8700K
Safe overclocking tips for i7 8700K
I'm just starting out with overclocking and have some questions about whether a 5ghz setting is suitable for my CPU. This machine is mostly used for converting and editing video and audio files, and I'm aiming for maximum performance. The current specs are a stock i7 8700K at 3.7ghz, paired with a Gigabyte GTX 1050 GPU, 16gb Gskill RAM, and idle temperatures around 25°C. When running at full capacity, the temperature stays between 73 and 74°C, never exceeding 50°C, and it remains stable at around 5020 MHz without any crashes or performance drops. I've checked with CPU-Z and found that under heavy load, the VCore decreases slightly but stays within a safe range, so it seems stable overall.
The maximum overclock you can achieve with an 8700K depends largely on obtaining a high-quality chip. As of March 22, 2018, the percentage of I7-8700k chips that can reach aggressive voltages around 1.4 with delidded cooling is as follows: 4.9% at 88%, 5.0% at 99%, 5.1% at 54%, and 5.2% at 22%. This caveat about delidded chips applies, as it enables better thermal management. Gradually increase your multiplier, keep an eye on the Vcore using cpu-Z, and avoid letting it reach 1.4 or slightly lower. Limit stress test temperatures to 85°C. Using speedstep and adaptive voltage will reduce both the multiplier and Vcore during idle periods.
The 8700K is capable of reaching 5GHz provided adequate cooling is available. You might require an all-in-one cooler or a high-end air cooler to achieve this.
The 8700K can reach 5GHz easily with adequate cooling. You might need an AIO or a high-end air cooler. I own the Cooler Master Hyper 212 Evo and it maintains a good temperature compared to other air cooled 8700K models. Do you have any suggestions for reference guides?

Note the caveat about delidded chips—it enables better cooling. Gradually increase your multiplier, watch your voltage with cpu-Z, avoid reaching 1.4 or lower, and keep stress test temps under 85°C. Using speedstep and adaptive voltage will reduce both multiplier and voltage when workload is low.

The maximum clock speed for an 8700K depends on your chip quality.
As of 3/22/2018, the percentage of I7-8700k chips that can run at an aggressive vcore around 1.4 with delidded 4.9 99%, 5.0 88%, 5.1 54% and 5.2 22% is noted.
This doesn't mean the chip can be cooled poorly; it just allows better thermal management.
Increase your multiplier slowly.
Watch your vcore using cpu-Z—avoid letting it reach 1.4 or slightly lower.
Limit stress test temperatures to 85°C.
Use speedstep and adaptive voltage, which will reduce the multiplier and vcore during idle periods.
Thanks, I'll try 5GHz if safe and report back when it works.
Your main way to stay safe is using vcore. The chip will slow down or stop if it senses a high temperature, which is near 100 degrees.
Your key to safety is vcore. The processor will slow down or shut off if it senses a high temperature, around 100°C. I managed to reach 5GHz without issues, but noticed the VCore fluctuates slightly under load. At 1.304V it usually drops to about 1.2V, isn’t that typical? The temperature stabilizes at 73°C during the stress test on CPU-Z.
Geofelt:
If you're steady and vcore isn't too high, that's enough.
I don't get into the small details of overclocking.
What you're seeing is probably vdroop.
Thanks a lot for your assistance.
