Hello There!
I recently increased my I5 6600k's speed by overclocking it a week ago, setting it to 4.5ghz with a voltage of 1.270v. During stress tests like AIDA64, I didn’t encounter any issues, but when playing games such as GTA V, after about 40 minutes or so, the system would crash. Sometimes it would display a blue screen with a sad face.
I’m trying to gather data from the problem but it keeps getting stuck, and other times the game freezes completely on the screen, forcing me to restart the PC.
I’m quite new to overclocking, so I can’t pinpoint the exact cause. I suspect it might be related to the VCore, but I’m raising it to 1.280 and still experiencing crashes. I really need your assistance to achieve a stable clock.

PC details:
Motherboard: MSI Z170A SLI (No Plus version: https://www.amazon.com/gp/product/B01DDR...UTF8&psc=1)
CPU: i5 6600k
GPU: MSI GTX 1060 Gaming X 6GB
RAM: Gskill TridentZ 2x8GB 3200Mhz
Cooler: Hyper 212 EVO
That’s all I have, please help me get a stable clock.

It looks like you've been unlucky with the silicon selection. Your particular chip requires 1.33V to operate stably at 5.5 GHz.

It seems your OC isn't behaving well. I recommend running a Prime95 small FFT test for one hour to check.
You might need a higher Vcore for the 4.5 GHz frequency.
Your PSU may not provide enough stable power for this overclock. Could you share the full make and model?
It's possible your motherboard lacks sufficient power phases for such an upgrade.
Alternatively, it could be that your CPU chip has reached its physical limits.

Hey, your PSU is an EVGA SuperNOVA 750 G2 80+. You're wondering about the Mobo, right? You managed to get it at 4.3GHz with a stable voltage of 1.275V. Then you increased the vcore to auto and noticed it dropping to 4.5GHz with a voltage of 1.35V.

Standard configurations often set Vcore excessively high. Consider increasing it to 1.3V at 4.5 GHz.

Kasper, adjusting the CPU to 4.4ghz at 1.3v remains unstable and odd. To achieve stable performance at 4.4ghz, I need to set the voltage to a minimum of 1.33v, increasing it from 1.28v all the way up.

It looks like you've been unlucky with the silicon lottery. Your particular chip requires 1.33V to operate stably at 5.5 GHz.
