5820k voltage over 1.3

[AdamX99]

Hi, I've recently built my first PC after many years of buying off the shelf macs, I have an ASRock Extreme 4 and 5820k with Liquid cooling in a large tower, the Motherboard comes with an OC Tweaker in the bios with an easy drop down menu for overclocking (a sin to use I'm sure I'll be warned) however, the lure of a one click option to overclock has drawn me in, my only concern is that when I run the CPU at 4.6ghz the voltage is set automatically to 1.32v, various forums indicate that I can achieve these speeds at lower voltages! Upon stress testing at 4.6ghz using the inbuilt easy option, the CPU temp sits at a steady 65 degrees C with fans happily sitting away at circa 1000rpm. I'm pretty happy with this but my concern is that by pushing the volts over 1.3 I am causing damage or unnecessary wear to the CPU? Should I have these concerns with such low temperatures? Thanks

that voltage is okay, but I would recommend going into advanced mode and seeing if you can not push your chip further at that voltage, or if you can lower the voltage slightly. that is not going to have much of an effect on the life of the processor, however, extra voltage is extra heat. look at it this way. perhaps running the CPU at 1.35+ volts and letting it get into the 70s might take a year or two off of the processor's life, but considering that those things can last for a decade easily, by the time it does croak, it will be long obsolete.

I would say try to keep it under 1.35 volts but really it's up to you. Heat kills processors much more than over-voltages so be careful and don't let it get to high. If this is your first time over-clocking I say watch a video or two to learn the basics and you should be good. You should be able to get a bit more 4.6 ghz at that voltage but not much more so don't worry. Anyway an extra 0.1 ghz won't make much difference.

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 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.

Cool, I've got a Corsair H100i so maybe ramp it up a little more!

you could always try to go further, we let the end voltage be 1.38 because we needed the 4.7 GHz clock speed and it is a top of the line render server that will probably be decommissioned in three years, so the CPU can take a bit wear. although the temps never got over 75, so I doubt that will even make much of a difference.
