This contact frame replaces the OEM AM5 buckle used to secure the CPU in the socket. By applying universal pressure to all points of the CPU, it is a considerable improvement on the OEM solution, which places it on only two points of the processor and can lead to warping. AM5 is the standard socket for all AMD Ryzen 7000 and 9000 series processors. If you are unsure of the socket type of your CPU please message us and we can help.
