5820k voltage over 1.3
5820k voltage over 1.3
Hi, I just set up my first PC after years of buying prebuilt machines. I have an ASRock Extreme 4 and 5820k with liquid cooling in a large tower. The motherboard includes an OC Tweaker in the BIOS with a simple drop-down for overclocking—definitely something to watch out for. However, the temptation of a one-click overclock option has drawn me in. My main worry is that when I run the CPU at 4.6ghz, the voltage is automatically set to 1.32v, but forums suggest I can reach those speeds with lower voltages. During stress testing at 4.6ghz with the built-in easy mode, the CPU temperature stayed steady at around 65°C while fans ran at about 1000rpm. I’m satisfied with these results, but I’m concerned that pushing voltages above 1.3 might cause damage or unnecessary wear. Should I worry about this at such low temperatures?
that voltage is fine, but I suggest trying advanced mode to check if you can't push your chip further at that level, or if lowering the voltage slightly would help. this won't significantly impact the processor's lifespan, though extra voltage generates more heat. think about it this way: running the CPU at 1.35 plus and keeping it in the 70s for a year or two might reduce its life, but since those components can last a decade, by then it will be long past its prime.

I would suggest keeping it under 1.35 volts, though the decision is yours. Heat damages processors more than over-voltages, so be cautious and avoid high temperatures. If this is your first time over-clocking, watching a few videos to understand the basics will help you succeed. You should be able to reach around 4.6 ghz at that voltage, though not much higher. An additional 0.1 ghz won't significantly affect performance.
Robert Cook suggests checking advanced mode to determine if pushing the chip further at that voltage is feasible. He advises either increasing the voltage slightly or lowering it, noting that extra voltage generates more heat. He explains that running the CPU at 1.35+ volts and allowing it to operate in the 70s could reduce its lifespan by a year or two, but since such conditions can last a decade, the device would likely become obsolete long before then.
Thank you, it did indeed crash during test number 8 at 65 degrees. I'll start investigating further.

Thanks, it actually crashed on test number 8 at 65 degrees? Not sure why but I'll do a little digging? It could need more voltage. Boost it slightly. I ran into that with a 5930K. It would seem stable and pass a bunch of tests, but then would fail under rendering. So, we just raised the voltage about 5/100ths of a volt and it was good to go. We had a thermal take water 3.0 so we could afford to raise the voltage.
Robert Cook shared his experience regarding a crash on test number 8 at 65 degrees. He mentioned uncertainty about the cause but plans to investigate further. He noted that the issue might require higher voltage, suggesting a slight boost. He recalled similar problems with a 5930K unit, which stabilized after adjustments. Raising the voltage by about 5/100ths of a volt resolved the problem, and they had enough thermal capacity (3.0) to make the change.
Great, you have a Corsair H100i and might want to crank it up a bit more!

You could always try pushing it further, we set the end voltage to 1.38 because we required the 4.7 GHz clock speed. It's a high-end render server that will likely be retired in about three years, so the CPU can handle some wear. Although temperatures never exceeded 75, I think it won't make much of a difference.
