Intel Core Ultra 9 Desktop Processor 285K - 24 cores (8 P-cores + 16 E-cores) up to 5.7 GHz

Working well

I like it It is stable, fast , without heating ... Easy to install

Excellent processeur, stable et performant dans les applications de productivité mais aussi en jeux, bien aidé par les derniers microcodes d’Intel et les optimisations des firmware de carte mères. Bien moins energivore que les générations précédentes Raptor Lake. Contrôleur mémoire bien mieux optimisé.

Wat kun je hierover zeggen? Lekker snel, wel prijzig, maar dat weet je op voorhand. Het is de bedoeling de pc te gebruiken voor AI.

Procesador , espectacular no da ningún problema nada que ver a las generaciones 13 y 14, es ponerlo y a correr , me sorprende también los bajos consumos que tiene y lo fresco que se mantiene, no te voy a engañar si haces overclocking si suben bastante las temperaturas y necesitas una buena refrigeración líquida. Pero en potencia y para jugar va muy bien,

My latest build June 18, 2025 was an all blackout no ARGB workstation to run SolidWorks: Intel Core Ultra 9 285k, MSI MAG Tomahawk Z890E wifi motherboard, G.Skill Flare X5 DDR5 64GB 6000 MT/S, Samsung 990 Pro SSD 1TB M.2, Thermaltake Toughpower GF A3 1050 watts power supply, upHere 8x6mm heat pipes direct contact 280Watt TDP CPU air cooler, Corsair 4000 RS Frame case, Corsair RS 120mm case fan, and PNY Nvidia RTX 2000 ADA 16GB GPU. The first thing I did was to update the BIOS on the mobo. With nothing(no RAM no CPU) on the mobo I inserted a 32GB USB flash drive with the latest BIOS file on it into the BIOS flash USB port, connected the power supply 8-pin and 24-pin cables to the mobo, turned on the power supply and press the BIOS flash button on the mobo, and in about five minutes the BIOS update was done (the LED light went out). Assembled all the parts into the case. I applied a very thin and even layer of thermal paste to both the CPU and the CPU cooler. For air flow I did three 120mm fans intake in the front and one 120mm fan at the rear. This fans arrangement forces cool air to flow across the entire motherboard which cools the RAM, VRM, help CPU air cooler intake and the GPU. I ran Cinebench 2024 and Core Temp for a10-minutes multicore stress test. With all 24 cores running at 100% the temperature range for all cores varied from 73 to 78 with every now and then a couple of cores spiked to 82 on for a few seconds then came back down under 80 degrees. The 285k drew around 205watts during the stress test. Even all six fans (four on the case, two on air cooler) rammed up to 100% the whole system was not noisy at all. I let the system burnt in for 24 hours and not a single hiccup. The CPU was very stable, the temperature was low and the system was very quiet. The Nvidia RTX 2000 ADA 16GB GPU is not for gaming and this system was not intended for gaming but for work station doing CAD type program specifically SolidWorks. I did a similar system back in January this year with the same CPU and mobo and I must say I was and I am impressed by the performance, reliability and stability of the Intel Core Ultra 285K and MSI MAG Tomahawk motherboard. Final thought: In day to day real life working with SolidWorks the 24 cores of the CPU will hardly reach 100% capacity. This is an over-built quiet system with a lot of horsepower to spare and most importantly a stable system for professional work.

Great CPU when using the latest mobo bios, however the latest Intel 200S BOOST update thing is a useless gimmick. On the Asus Proart board, the XMS tweaked profile gives far better speeds and lowers the ram latency by 17ns which doesnt OC the CPU at all.
