Processor Intel Ultra 9 285K, 5.70 GHz, 4 Cores, 36M Cache, FCLGA18W

The Intel Core Ultra 9 285K is a desktop processor from Intel's Arrow Lake family, designed for high-performance desktop systems. It supports the FCLGA18W (socket 1851) platform and combines performance and efficiency cores to deliver up to 5.70 GHz turbo frequency, DDR5 memory support and integrated Intel graphics. The processor is suitable for workstations, gaming rigs and productivity desktops that require multithreaded performance and platform security features.

Advantages

This CPU offers a hybrid core architecture with 8 performance-cores and 16 efficient-cores (24 cores total) and 24 threads, a large combined cache (36 MB CPU cache and 40 MB L2), and high turbo frequencies (up to 5.70 GHz) for single-threaded bursts. It supports DDR5 memory up to 6400 MHz, PCIe 5.0 lanes, a broad set of Intel platform technologies (including vPro, Turbo Boost, Deep Learning Boost, Turbo Velocity Boost and advanced security and manageability features) and a 36-month warranty with serial-number validation.

Suitable for

• Multithreaded workstation applications (video editing, 3D rendering)
• High-performance gaming builds
• Software development and compilation tasks
• Business desktops requiring manageability and security (vPro)

How to use

Install the processor into a compatible motherboard with FCLGA18W (socket 1851) following the motherboard and CPU manufacturer instructions. Use an appropriate cooling solution rated for the processor's TDP and ensure correct BIOS support for Arrow Lake CPUs and DDR5 memory. Apply compatible DDR5 memory modules in the recommended slots to enable dual-channel operation, and configure BIOS settings for XMP/overclocking only if your cooling and power delivery support higher frequencies.

Usage recommendations

For reliable operation in high-load scenarios, pair the Intel Core Ultra 9 285K with a motherboard that provides robust VRM design, a quality CPU cooler, and DDR5 memory certified at 6400 MHz or the motherboard-supported speed. Keep firmware and chipset drivers up to date to take advantage of security and performance features.
