14-core Arrow Lake desktop CPU
The Intel Core Ultra 5 245KF is a 14-core desktop processor with six performance cores and eight efficient cores. It fits the LGA 1851 socket and has a 125 W base power rating. The chip is sold as a refurbished unit without integrated graphics.
Best for discrete graphics builds
This CPU suits builders who will pair it with a dedicated graphics card and want PCIe 5.0 and DDR5 6400 support. Systems that rely on integrated graphics or need a lower power envelope should look at other models.
125 W base power decides cooling
The processor runs at a 125 W base power with performance cores reaching up to 5.2 GHz and efficient cores up to 4.6 GHz. Your cooler and case airflow must handle this thermal load for sustained boost clocks.

คำถามเกี่ยวกับสินค้านี้
What motherboard socket does the Core Ultra 5 245KF require?
The processor fits the LGA 1851 socket, so the motherboard must use that exact socket.
Which step is often missed when installing this CPU?
Applying thermal paste and securing the cooler before powering on is the step people forget, and the chip has no integrated graphics to fall back on.
What memory will need replacing if I upgrade capacity later?
The CPU supports DDR5 6400 in dual-channel up to 256 GB, so any future capacity increase means buying DDR5 modules.
