How do I override my CPU Voltage?

[Arya]

I've got a new 6700K. After a lot of tinkering it's running beautifully and delivering a lot of power, but it's running a higher Voltage than is necessary to keep it stable. I want to drop the Voltage down so it'll run cooler and last longer, how should I apply that?

It's running 1.35 max voltage right now, that's safe but it's unecessarily high. From what I understand I can drop it down into the 1.25 range without any loss of function - and get colder temps by doing it. Given it's the height of summer, cooler temps would be very welcome.

run voltage setting in bios only.. turn off auto for vcore voltage and set it to desired voltage 1.25-1.3 auto will ramp up voltage.. turning on llc (load line calibration) if you have it will help regulate voltage as well..

keep in mind in turbo the voltage will go up somewhat that might be what your seeing as well

Thanks. And you're right, I think it's Turbo that's been kicking the voltage up.

I scored a jackpot in the Sillicon lottery, my chip is stable at 4.55 GHz at 1.35 Vcore and 66 degrees. Which is why I want to turn it down - running above 4.2 isn't getting me any extra performance in-game, so I may as well maximise the life of this rather lovely chip.

If you want to maximize lifetime, then just leave it on stock. Pretty much everything else in your PC will derp out long before the CPU.

Alright, thanks.

It's taken a lot of fine-tuning in BIOS to get everything working just right, but holy crap it's been worth it. This PC is a monster.

I mean, you can always screw around with voltages, and i'm a huge fan of downclocking and undervolting myself, but you may cause a lot of instability. Stock frequencies will serve you well for ages, and a slight & plain frequency OC won't cause any harm either (*if properly cooled obv.)

If i may ask: in another topic you wrote something about a 3770k. Why did you upgrade to a 6700k?

[Arya]

I do have a 3770K, but that system had a lot of problems and I decided that - given the amount of parts needed to rescue it - I may as well buy a full new system and start from scratch.

Just get rid of SpeedStep and Turbo; then manually OC the CPU (even if all you do it manually run it at the Turbo speed) and then get that VCore off Auto and lower it until stress tests are stable runs. VCore on Auto will always be way too high.

Thanks! Will do.
