Overclocking study – Intel Core i7 4790K & Intel Pentium G3258 – air, water, phase-change, DICE & LN2


Ok, I hope you enjoyed your reading today. If you got here and you liked the article, we have two bonus pages for you. The first bonus is … the beer cooled PC!!! Using the same gear as we did in our extreme water cooling section (EK-Supremacy Clean CSQ + EK-DCP 4.0 PWM) we replaced the water and antifreeze with chilled beer (7.5L of beer and 5KG of ice) and we took the whole system on the romanian national television (ProTV). Live, during the morning news we easily managed to get to 5.2GHz. We could have gone to 5.4-5.5GHz but we didn’t want to get any blue screen on live TV so we didn’t push our beer cooled rig too much.

And you should also know that we used a very “special” kind of beer, which can be purchased for the extraordinary price of 1.66 USD / 2.5L… So….yeah… beer is good for cooling you, but it can also be used to cool your CPU… And instead of a potato, here is a 2.5L beer !!!

    16. You had to go up to like 1.35V or higher to get your 4790k to almost 4.8ghz?
      I set my BCLK has high as it would go at stock (101.5), set voltage to 1.30 fixed, set multiplier to 50, knocked it down until it would boot (48), knocked it down to temperature within operating ranges (47), and then tweaked the voltage down until it stopped, then set it to Adaptive, with a max of just above where it stopped.

      result: 1.23V 4770.5MHz

      Then I bumped CPU Cache till it wouldn’t work anymore, at 45x.

      Max temp at 86 degrees. No matter what I set voltages to I can’t get it to operate at 48x without it constantly going into thermal throttle. Works fine at 47x.
      I can even get it to do 48x on one core, so long as I don’t start up GTA V.
