Could exceedingly high vcore settings lead to instability in your overclock?
I have an i6600k and was following a guide on overclocking.
The first step was to go to 4.4 ghz with a vcore of 1.35, then adjust according to stability tests upwards of 0.05 to 0.1.
I tested my system for 20 minutes at 1.35 and noticed three out of four workers stopped.
At 1.36 it worked fine for 20 minutes.
Then I left it there a bit longer; temperatures reached about 84°C with a hyper evo.
Next, I considered that the higher vcore might have been unstable.
The recommended settings were 1.3v, 1.35v, and 1.36v.
I tried 1.30v and was stable for 20 minutes of prime95 and passed an overnight test.
Does this make sense?
Could the instability be due to testing errors or memory issues?
Sure, it does make sense. There are different sensors in the CPU and memory modules designed to protect against high voltages. Even if a certain voltage is set, there can still be higher transient voltages that trigger some safeguards. These events are too brief for the SW to register and are hard to detect.

Overclocking by merely searching reference data and voltages in manuals isn't sensible and could endanger your CPU.
You should begin with the desired frequency and gradually raise the VCore in tiny increments until stability is achieved. Keep in mind that each CPU is different and needs its own voltage for a stable overclock.
Regarding your question: I haven’t reached such high VCore values yet, and it seems they cause instability unless combined with other issues like voltage spikes or excessive heat.
I usually keep trying until I find the optimal balance between clock speed and voltage. For my 3700k model, it’s currently around 4.3GHz, but all these factors mean increasing VCore too much isn’t effective.
