Determine the appropriate voltage for overclocking a 6700k CPU to 4.6 or 4.8ghz.
Determine the appropriate voltage for overclocking a 6700k CPU to 4.6 or 4.8ghz.
I received a response from ASUS stating they adjust the motherboard's voltage to ensure CPUs always operate. I’m not very familiar with the details. What voltage should I use for a 4.6 GHz processor? And for 4.8 GHz? What voltage is considered too high, and how fast could a CPU fail if the voltage is excessive?
1. Likely around 1.3, though it changes depending on the chip.
2. Possibly 1.35 or 1.4, but not advised unless using water cooling.
3. Anything above 1.45 that maintains for over 30 seconds, unless it involves extreme water cooling or LN2.
4. It's hard to give a definite answer since no testing has been performed; higher voltage generally reduces lifespan, especially with lower current.
every cpu increases performance in its own way
my preferred setting stays under 1.4v with good cooling
some users push beyond 1.4v but I tend to avoid it
rough guide: 1.35v for 4.6ghz
1.4v for 4.8ghz when the processor supports it
Is 1.425 volts too low for the system? From what voltage level on the CPU would it typically cause damage?
every cpu has its own overclocking behavior
my personal setting stays under 1.4v as long as the cooling is good
some users push higher than 1.4v but i tend to avoid it
rough guide suggests 1.35v for 4.6ghz
1.4v works for 4.8ghz if the processor supports it
i achieved 4.8 with 1.28
The maximum overclock level depends on the quality of your chip. Intel limits it to a maximum of 1.5v, but you might only be able to go up to around 1.4v before issues arise. As of May 2016, the percentage of users who could successfully overclock at a stable 1.40v Vcore varied. For the I7-6700K, the percentages were: 4.9% at 2%, 4.8% at 17%, 4.7% at 59%, 4.6% at 93%, and 100% at 1.4v. You can run your I5-6600K at 4.8 with 1.4v and 1.4v is a well-binned chip, requiring minimal cooling—just an air cooler with a 120mm fan. Adjust your OC settings so that voltage and clock speed decrease when the CPU isn’t under load; Speedstep and adaptive voltage can help with this.

mcnumpty23 shares their experience
every CPU overclocks at a different rate
my preference stays under 1.4v, as long as cooling is adequate
some users push higher than that, but I tend to avoid it
a rough estimate suggests 1.35v for a 4.6GHz CPU
1.4v works for 4.8GHz if the processor supports it
I achieved 4.8 with 1.28
it seems you might have been lucky, making this question less relevant
since it clearly points to a very safe voltage range

every cpu overclocks differently
my personal pick stays under 1.4v with good cooling
some go beyond that but i avoid it
rough guide: 1.35v for 4.6ghz
1.4v for 4.8ghz if the cpu supports it
I achieved 4.8 at 1.28
I don’t think that’s possible… probably a "boot to desktop" voltage
run a stress test, prime95 or high-end game (GTA V PC) and I’ll confirm
also why do folks ignore Load Line Calibration and Current Capacity?
they’re crucial for a clean boot… LLC is correctly LVL 7 and Current Cap
140% in that range would likely work
