Adjusting my i7-7700K to 5.0Ghz at 1.270V caused crashes.
Adjusting my i7-7700K to 5.0Ghz at 1.270V caused crashes.
Hello everyone,
I'm just starting out with OC and have been spending a lot of time researching and watching YouTube tutorials. I'm still a beginner and really need your advice.
My system is an i7-7700K with H100i v2 cooling and an MSI z270 M5.
Last night I tried to overclock to 5.0Ghz at a core voltage of 1.270V. The AIDA CPU stress test showed stable performance and good temperatures. I skipped the FPU stress test because it would have immediately indicated overheating.
Later, when streaming CSGO at high quality, I managed to play for about 30 minutes before encountering a blue screen. The system worked fine at 5.0Ghz with stable temps, but crashes only occurred during streaming and high settings (CPU usage peaked at 85-95%).
I increased the voltage to 1.275V and the stress test revealed temperatures above 90°C. Then I reduced it back by -0.005V.
I checked online and saw that most people use 1.3V for this overclock, but since I got high temps at a lower voltage, I didn’t investigate further.
Could anyone help? Should I adjust the frequency or try a higher voltage? Or should I tweak RAM speed? Also, XMP was disabled throughout the process.

Updated: I achieved an OC of 4.8 with a voltage of 1.270V and stressing with prime95 was effective for an hour now. It’s clear that’s not sufficient, but after that I streamed for two hours without any crashes—those results are promising and could support longer tests.
Temperatures hit 100°C several times during the stress test, yet while gaming and streaming at high quality and 2k graphics in CSGO, they never exceeded +85°C.
There seems to be an issue with your cooling system; you shouldn’t approach even close to 70°C when gaming and streaming at this voltage. I use prime95 on my 7700k clocked at 5GHZ, under a budget cooler in close match conditions, and the temperature never reached 80°C.
You should address your cooling first before attempting overclocking—try...
You need to understand why it gets so hot. Have you installed the cooler correctly? Check out some tutorials on YouTube to confirm you did it properly. Ensure the pump is connected and the fans are working. Also, note that the voltage is too low for 5GHz.
Makentox, check why it gets so hot. Did you install the cooler correctly? Look up some guides on yt to confirm your setup. Ensure the pump and fans are connected. Yes, the voltage is too low for 5ghz.
Hello Makentox, thanks for the update.
It’s strange, but my cooler is functioning well. Idle temps stay between 25-35°C, reaching 60°C during gaming (without overclocking).
What should I do with the voltage? Should I just set it to 1.3v? People often mention the optimal setting for OC, but what if this model isn’t compatible?
Note: The temperature stays stable at v1.270, not exceeding 80°C under heavy load (streaming and gaming) on 5.0.
You can review this graph to see the comparison. My outcomes with 7700k were 1.310v at 5ghz, temperature stayed under 80°C during the Intel burn test, and I was using a cryorig h7 which is a budget cooler. http://www.overclock.net/t/1621347/kaby-...statistics
Consider trying an Intel burn test—it performs best for me. Aida doesn’t work well... I can handle Aida for several hours before crashing in Cinebench R15 or browsing the internet.
Each chip behaves differently, so you should just raise the voltage until it stabilizes. Some users reach 5ghz at 1.3 while others need 1.35. Be careful not to touch anything near the multiplier and manual (static) voltage until you identify a stable voltage range. Watch for voltage drop during the stress test. If it falls below 0.030+, modify the LLC in BIOS and set it higher.

Each chip behaves differently, so gradually raise the voltage until it becomes stable. Some users reach 5GHz with a multiplier of 1.3, while others require 1.35. Ensure you avoid touching anything near the multiplier and manual settings until you identify a consistent voltage range. Watch for any voltage drop that occurs during the stress test. If the drop is above 0.030%, adjust the LLC in BIOS and set it to a higher value.
I understand, but could you clarify the last part? Would a YouTube video or a link explaining how to check voltage drop and what signs to look for help? Thanks again.

You should address your cooling first before attempting overclocking. Consider replacing your cooler or remounting it with extra thermal paste. Download Corsair software to monitor fan/pump speeds. You can also visually inspect if all fans are spinning and feel the pump vibration or hear it during heavy load.
