With the development of cloud computing applications, informatization gradually covers various fields of society. People's daily life and daily life are more and more communicated through the network, and the network data volume is also increasing continuously. In order to meet the increasing demand of information services, the functions of the server are also more and more abundant. According to moore's law, the number of circuits integrated on an integrated circuit chip doubles every 18 months.

Server motherboards are also becoming more complex to support more and more functions. Due to the particularity of the operation of the server mainboard, the requirement on the signal transmission rate is higher and higher. Therefore, in order to better perform the power integrity test of the server board, especially to implement a more accurate test on the power integrity of the CPU and the Memory VR (Voltage conversion), Intel makes detailed test specification and test specification on the power integrity test, and pushes a corresponding test tool to better assist in completing the VR test of the CPU and the Memory.

For VR testing of Memory, it is necessary to complete testing with Dual Inline Memory Modules (DIMM) VRTT (Voltage conversion Test Tool). The voltage and current conditions of each group of DDR under a certain test condition can be effectively surveyed in real time by the tool.

The existing connection modes of DIMM cards comprise flexible cable connection and hard board card connection, wherein the flexible cable connection is realized by connecting each independent test tool through an electric wire, the distance between the flexible cable connection is small, and if the flexible cable connection is simply pressed by hands, poor connection is easy to occur, so that the test time is wasted; the distance between the hardboard cards is large, the hardboard cards can be pressed by hands, but PIN needles on the hardboard cards are protruded, and if the hardboard cards are directly pressed by hands, the hardboard cards are extremely easy to be injured and are not beneficial to the personal safety of operators.
