[0002] A server is a device used to provide computing or application services in a network environment. It works by installing various modules on the motherboard, including processors, RAM, and other modules. As the functions of server motherboards in the manufacturing industry continue to increase, the performance requirements for testing memory modules are also gradually increasing. The CPU architecture is constantly updated and the server motherboards under test are constantly upgraded. The new technology field of DDR5 has higher performance, larger DIMM capacity, stronger data integrity, and is easier to maintain. In order to ensure the normal operation of the server, the connectors connecting the processor and RAM on the motherboard and the corresponding module functions need to be tested to check the reliability of the corresponding functions. Directly connecting the memory card for testing does not allow the specific location of the fault to be obtained, which is not conducive to maintenance and adjustment after the motherboard function test.
