i5-6600k keeps crashing
Hello,
I attempted to increase my CPU's clock speed after 18 months of use for the first time.
I mainly play CPU-intensive games such as CPU PUBG and R6, where the processor reaches full capacity and it affects my consistent performance in competitive matches.
This is my initial overclocking attempt; I was aware of the potential risks and followed the recommended steps.
Below are the components I used.
Initially, I tried the default settings at 4.2 and 4.4 GHz, but temperatures rose to 75-85°C.
Then I experimented with a multiplier of 42 and 44, which kept temperatures around 65°C.
I tested voltages of 1.25, 1.275, and 1.3 for each multiplier.
I ran the Intel Extreme Tuning Stress Test for 30 minutes on each setting and observed no issues while monitoring with CPU-Z and HWMonitor.
I also tried enabling and disabling XMP profiles.
What could be going wrong?
Prime95 version 26.6 is available on this site. Anything above that version also evaluates AVX instructions, which are relevant for scientific research tasks. It generates significant heat and may lead to instability.
Two of the cores failed. I recommend increasing the vcore slightly—try 1.3 or 1.31v. When using an i5 [email protected], my vcore was 1.328v.

Adjust the load line calibration to medium or the center; this should enhance system stability under heavy CPU usage.
zyh1987:
adjust the load line calibration to medium or the middle, as I forgot whether it relates to a specific number system. This should help with stability under high CPU load.
I checked LLC and can select Off, Level 1, Level 2, Level 3, or Level 4.
I switched to level 1 but the system still crashes. I don’t understand why it isn’t stable.
Increase your core voltage by one step. Also, let llc provide a graph illustrating that lvl1 remains flat while lvl4 slopes upward; you’d prefer 2 or 3 levels. Here’s the excellent guide by Der8auer—though it applies to an Asus board, you can compare it to an Asrock board.

So: I followed the video instructions. I raised my Vcore to 1.28 and set a 44x, then adjusted XMP to Profile 1 and LLC to Level 2.
I ran Intel Extreme Test for an hour and everything was normal—temperatures stayed below 68, and I didn’t see any bluescreens during gaming.
After that, I tried Prime95 as shown in the video. But then problems started:
Prime95 didn’t work on all cores after just one minute. When I began the small FFT, only two out of four cores were active (probably because only two temperatures rose to around 80, while the other two stayed at about 40).
What’s going on here? Any advice?
Prime 95 test, was it a crash or just insufficient stress on all four cores? Also, in the power setting, switched it to performance mode.
