Intel Core i9-12900K bumped up to 8 GHz along with overclocked DDR5 memory

In short: Intel Alder Lake processors and motherboards were just starting to ship to enthusiasts around the world, and the overclocker community wasted no time pushing them to their limits. The latter result was achieved by popular overclocker HiCookie, who managed to overclock the Intel Core i9-12900K to a whopping 8GHz.

The Intel Core i9-12900K is already a beast in terms of performance at stock settings, but that hasn’t stopped overclocking enthusiasts from pushing it further to find its limits. Last month, a popular guy in the overclocking community managed to get Team Blue’s latest flagship processor up to par. 6.8 GHz for Golden Cove cores (performance) and 5.3 GHz for Gracemont cores (efficiency). That means 31 percent overclocking P-cores and 36 percent overclocking E-cores – enough to set new Geekbench 4 and Geekbench 5 world records in both single and multi-core tests.

Taiwanese overclocker HiCookie achieved even more impressive results this week when trying to overclock P-cores, with the highest stable clock speed at a respectable 8GHz. HiCookie proudly announced the results on Gigabyte’s Spanish Twitter account for the Aorus sub-brand, along with screenshots of the CPU-Z bid. The 8GHz overclocking required setting the multiplier to 80x, and the V-core to 1.81V.

To do this, the overclocker used liquid nitrogen (LN2) cooling, a Gigabyte Z690 Aorus Tachyon motherboard and one 16GB DDR5 memory card. Along with overclocking the processor, HiCookie also increased the effective speed of the DDR5 module to 8300 MHz from the default 4800 MHz specification.

For reference, Intel’s flagship Rocket Lake has been bumped to around 7.33GHz, while the highest recorded overclock for the Core i9-10900K (Comet Lake) is 7.7GHz. The highest CPU overclocking ever recorded was achieved with the AMD FX-8370 (Piledriver), which was overclocked to 8.7 GHz.

Judging from this first series of overclocking results, Team Blue’s latest flagship desktop processor could have the potential to reach new heights if someone finds an even higher quality sample to play with.
