I've been pushing my Athlon X4 860K to 4.0ghz with a 1.49 vcore for a week now. I did some checks and learned that using a higher vcore can reduce its lifespan (really scary!). How much does it actually last? If I start with a brand new CPU and installed it properly with good cooling, how long should it last—months, years, or maybe just a year? I'm still getting used to overclocking.
You're just enjoying gaming lately. Mostly creating custom builds since Chrome slows down noticeably at 3.7GHz. I feel like I've got everything covered—power, VRM, cooling—and wonder if it'll hold up for a few months.
It’s not what you’re looking for, but a 1.49v at 4.0GHz is unrealistic. Unless you have a powerful FM2+ board, I’d be concerned about the VRMs before the CPU. It seems unlikely you need more than the standard voltage boost to run all cores at that speed. In fact, the stock voltage might be too high or too low for such high clocks (many FX chips handled this). It’s an intriguing point, but check if it really matters to you.
1.5V might damage a chip within about a year. That’s correct—I’ve worked with FX processors, and most of the boards I used didn’t perform well.
Avoid pushing the board beyond its limits—overclocking could damage the VRMs under stress. For a stable setup, aim for the lowest possible voltage that still meets your clock speeds. 4.0 It's reasonable to expect a much lower operating voltage than what you're currently using.
I'm a HUGE fan of undervolting, which is basically 'inverse overclocking'. Anyhow, my decade old Core 2 Duo E8400 used to run at 1,050mV back when it was new but now it requires a bit more voltage at 1,062mV otherwise it gets unstable and goes BSOD. Since the voltage ceiling is rather 'whopping' 1,200mV, I believe I can still squeeze out a decade or two out of that poor old thing. To answer your question, 1.5V sounds rather extreme and if you care about longevity and want to run that CPU for years to come then you better bring it down to rather humane 1.35-1.40V range. As for me, I undervolt my CPU and GPU solely to keep my PC as quiet as possible and the dramatically decreased power consumption is a bonus!
