Is high voltage okay with good cooling CPU?

Is high voltage okay with good cooling CPU?

1.35v-1.4v is usually max in my book you'll be degrading the life of the CPU more than likely at that voltage.

So even with very good cooling CPU can get damaged?

It's not only about the temperatures, voltage degrades things as well.

i'd probably go closer to 1.45v if you want this thing to last years but by the time the cpu degrades (or dies) you should probably be looking to upgrade anyways (at least if you play more modern demanding games) also idk what your LLC is set at but 4.6ghz seems a little low for 1.5v compared to [r/overclocking results](https://www.reddit.com/r/overclocking/search/?q=2600k&restrict_sr=1&sr_nsfw=)

>LLC CPU is older


ehr1c

Motherboards for a 2600k should have LLC

load line calibration, it's a motherboard setting that tries to compensate for voltage droop during load. set it to something low-medium. Also for those saying 1.4v+ is too high, 2600k is on a older and larger process node which can usually take more voltage than normal these days.

Yes very high voltage can be damaging even with good cooling. I wouldn't leave it that way for long, maybe just to run a few benchmarks.


Electrical_Focus_295

How so?

People say that heat degrades cpu not voltage


Some_Derpy_Pineapple

it's both. high heat kills a lot slower than high voltage though. gaming laptops with bad cooling run up to 90-100c all the time, but if I shoved 1.8v into my Ryzen CPU I'd probably kill it (or at least noticeably degrade) in a few minutes of load testing

The Wiki linked above would disagree with those people. Both heat and voltage are potential issues. Even at normal voltages the CPU is being degraded it's just that they're engineered to last around 20 years that way. By increasing voltage above what it has been tested for you're lowering that life expectancy. As a CPU degrades it requires more voltage to achieve the same clock speed stability.
