The flagship Intel Core Ultra 9 285K processor of the new Arrow Lake-S series was overclocked to 7488.8 MHz – almost 1.8 GHz higher than Intel’s stated maximum frequency for this chip. The processor was overclocked by the Elmor overclocker using the Asus ROG Maximus Z890 Apex motherboard and a lot of liquid nitrogen.

The overclocked processor set several new world performance records in various benchmarks, including the 3DMark CPU test for 1T, 2T, 4T and 8T profiles (one, two, four and eight threads, respectively). Additionally, the overclocked Core Ultra 9 285K scored an impressive 60,840 points in the Cinebench R23 benchmark.

Note that the Asus ROG Maximus Z890 Apex motherboard was used by other overclockers (BenchMarc, OGS, Dreadzone and CENS) to overclock G.Skill CUDIMM DDR5 RAM to speeds of 12,066, 12,046 and 12,042 MT/s, respectively, as previously reported . These records did not last long. They were overtaken by overclocker Kovan Yang, overclocking Kingston Fury Renegade DDR5 CUDIMM memory to a speed of 12,108 MT/s.

In terms of clock speed, Elmor did not surpass its previous record set earlier this month. Then the AMD Ryzen 9 9950X processor and the Asus ROG Crosshair X670E Hero motherboard were used for the experiment. The enthusiast overclocked this chip to a frequency of 7.54 GHz, thanks to which he also set many different performance records in various benchmarks, including Cinebench R23, Cinebench R20, Geekbench, 7-Zip and others.
The Core Ultra 9 285K processor is equipped with 24 cores – eight high-performance P-cores and 16 energy-efficient E-cores. The chip received 36 MB of L3 cache and 40 MB of L2 cache. Each P-core has 3 MB of L2 cache. Each of the four clusters has four E-cores and 4 MB of L2 cache memory. The processor supports dual-channel DDR5-5600 UDIMM or DDR5-6400 CUDIMM RAM, provides support for 20 PCIe 5.0 lanes and four PCIe 4.0 lanes (another 24 PCIe 4.0 lanes are provided by the Intel Z890 chipset of the motherboard).
