My 5820k will operate at 4.4GHz with 1.19V, yet it won’t reach 4.5GHz even when the voltage is raised to 1.35V. Did I succeed or did I fail? From what I’ve noticed, a bit more than 1.25V is usually needed for 4.5GHz, but I might be mistaken. I’m comfortable with 4.4GHz at 1.19V, and low temperatures are manageable, though this is my first attempt at overclocking the CPU, so there could be an error.

In the process of overclocking, a significant increase in VCORE is often needed for only a slight improvement in clock speed. This represents the overclocking barrier, indicating you've reached it. At 4.4Ghz you're effectively winning the lottery, while at 4.5Ghz you might lose it. Many observations suggest around 4.4Ghz corresponds to about 1.23V and 4.5Ghz to approximately 1.3V.

Did you verify the full stress test for the 4.4GHz overclock? Also, what temperatures are observed during idle and load conditions?

Following Prime95 26.6 for 20 consecutive hours under 70°C, I think it's stable. Idle temperatures are in the high 20s to low 30s, just a bit above ambient.
Edit: Apologies for not using the reply button. Chrome seems to be acting oddly today.
