This is a used Ryzen 9 5900x CPU, 3.7 GHz base, 4.8GHz boost.
This CPU spent much of its life in ECO mode to reduce power consumption. With a 240mm AIO cooler, it ran around 40º at idle and around 70º at full tilt. No bent pins or defects of any kind. I even saved the original box and packaging.
This CPU offers excellent speed and responsiveness for various computing tasks. The CU is designed for use with Socket AM4 motherboards, featuring a L3 cache of 64 MB and a bus speed of 3200 MHz for optimized performance. Ideal for demanding applications and gaming, the Ryzen 9 5900X is a top choice for those seeking a powerful CPU for their computing needs.
