CPU test system and server

Abstract

The invention provides a CPU test system, which comprises a first test board, a second test board and a controller, and is characterized in that the first test board is configured to provide a running environment for a first CPU and collect state data and running data of each module when the first CPU runs; the second test board is configured to provide a running environment for the second CPU and collect state data and running data of each module when the second CPU runs; the controller is configured to collect state data and operation data of each module on the first test board and the second test board and generate a test result. According to the CPU test system provided by the invention, when the number of PINs (Personal Identification Number) of signals such as MISC (MISC) transmitted by the onboard connector is not enough, the problems can be solved by converting parallel signals into serial signals and converting the serial signals into parallel signals. The problems of high test cost, low test efficiency and low test flexibility are effectively solved, and meanwhile, the heat dissipation problem and the generated environmental noise problem of a high-power-consumption CPU factory test are solved.

Description

technical field [0001] The invention belongs to the field of computers, in particular to a CPU testing system. Background technique [0002] In order to adapt to stronger data transmission and processing, CPU manufacturers are using the method of stacking cores to improve the performance of the CPU before the process reaches a further step. Other chip manufacturers will also carry out chip innovations to adapt to high-performance CPUs. Social progress has brought great productive capacity. At the same time, the power consumption of the CPU and the power consumption of the whole server are also rising, which brings great challenges to the factory verification of the CPU. It is not only difficult to test basic functions but also expensive. [0003] The CPU power consumption has been increased from 180W to 240W, and further increased to 280W and 350W. According to the latest platforms such as Intel and AMD, the CPU power consumption will reach more than 400W. Comparing Intel'...

AI Technical Summary

Problems solved by technology

[0004] like image 3 The traditional test and verification shown above all use the dual-channel design of the server motherboard to dissipate heat through air-cooling. The size of the board is relatively large, and it produces high environmental noise and high cost. After the CPU power consumption is greatly increased, this is achieved. Design is too difficult

Moreover, with the increase of CPU power consumption, it is more likely to cause damage to the motherboard due to high power consumption, and once irreversible damage occurs, the entire motherboard will be scrapped

The cost of testing increases dramatically
