Raptor Lake 9.1 GHz overclockers share secrets and techniques and strategies behind eclipsing a 17-year-old CPU frequency world file
Not approach again, we coated a world record-breaking overclock of an Intel Core i9-14900KS reaching a whopping 9.1 GHz. Throughout the time since, the group accountable had been invited to Intel to hold an extended presentation on how they did it [h/t Skatterbencher]. It is usually worth noting that this spectacular 9.1 GHz overclock was solely achieved on a single P-Core of the Core i9-14900KS CPU in question. The whole video presentation is embedded underneath, and as well as accommodates additional historic context and technical information on the achievement.
All through the presentation, an vital elements for attaining a world file in CPU overclocking runs are given. These embrace utilizing liquid helium cooling as an alternative of the additional well-known and customary liquid nitrogen, however moreover a combination of most temperature administration and sheer luck which might be very troublesome, expensive, or every to breed. Within the occasion you’ve got heard of the “silicon lottery” for attaining regular CPU/GPU overclocks, that might not apply additional to the sector of cutting-edge (nonetheless lastly unstable throughout the long-term) OCs like this one. For example, the golden sample Core i9-14900KS getting used is solely 100 MHz larger than totally different lottery “winners”.
As one might uncover from each the presentation or the header image we used for this write-up, overclocking headroom has trended to some extent of terribly diminishing returns since 2007, when 8 GHz was first achieved. Whereas desktop CPUs are recurrently climbing in complete effectivity and out-of-box Improve frequencies, it seems obvious that we’re starting to run into some extreme bodily {{hardware}} limits trying to comprehend 9 GHz and higher.
Even measuring CPU frequency exactly whenever you’re pushing it that prime requires a considerable quantity of expertise and even custom-made software program program, which SkatterBencher wrote for that exact goal and talked about all through the presentation. Moreover, with the “measuring it” downside in all probability solved, plainly 10 GHz and higher overclocks won’t be achieved on fashionable CPUs anytime shortly.
Who’s conscious of, though? Maybe if binding CPUs with diamond turns into widespread, the toughest cooling and vitality limits could possibly be overcome and produce us into the world of true 10+ GHz CPUs. In any case, we’re grateful to overclocking followers like SkatterBencher and ElmorLabs who chase these expensive and unwieldy world info. That is hoping we will not be prepared for for much longer to see this “unbeatable” file broken, even when it’s just by only a few hundred Megahertz.
