Embodiment

[0017] The detection device for quickly locating faulty memory sticks described in this embodiment has an overall structure as attached figure 1 As shown, the detection device mainly includes a server main board and an external digital tube small board, and the server main board is provided with a CPU, a BIOS chip, and several memory sticks extended by the CPU; Tube interface, the external digital tube small board can be connected to the self-test digital tube interface through the cable, and the detected fault memory location is displayed through the digital tube small board.

[0018] as attached figure 1 As shown, there are two CPUs on the mainboard of the server in this embodiment: CPU0 and CPU1, and each CPU can expand eight memory sticks. The corresponding relationship between the CPU and the memory sticks is as follows:

[0019] CPU0 corresponds to: CHADIMM0\CHADIMM1\CHBDIMM0\CHBDIMM1\CHCDIMM0\CHCDIMM1\CHDDIMM0\CHDDIMM1;

[0020] Corresponding to CPU1: CHEDIMM0\CHEDIMM...

Abstract

The invention discloses a detection device and method for quickly positioning a failure memory bank, and relates to a memory detection technology. The detection device mainly comprises a server mainboard and an external nixie tube small board; the server mainboard is provided with CPUs, a BIOS chip, a self-detection nixie tube interface and multiple memory banks expanded by the CPUs, and the nixie tube small board is connected to the self-detection nixie tube interface through a patch cord. According to the detection device and method for quickly positioning the failure memory bank, a memory failure code table is built, and when memory failure detection is performed, failure memory codes are displayed through the nixie tube small board and compared with the memory failure code table to quickly position the position of the failure memory bank; the time of server operators for excluding the failure memory bank can be saved, the workloads of the operators are reduced, the debugging efficiency of a server production line is improved, and the server productivity is improved.

Description

technical field [0001] The invention relates to memory detection technology, in particular to a detection device and method for quickly locating faulty memory sticks. Background technique [0002] Usually, on a general-purpose server motherboard, the supported memory sticks range from 8 to as many as 32. In the process of server production and assembly, if the memory module is not inserted properly or the inserted memory module is damaged, the server will often have a failure of no display when it is powered on during the power-on debugging stage. [0003] In order to locate the cause of the fault, the operator adopts the most direct method: unplug the memory sticks one by one, then insert the memory sticks into the motherboard one by one, and then turn on the power to see if there is a display when it is turned on, until the memory sticks are found. Replace the memory module or re-insert the memory module to eliminate the non-display failure. Due to the large number of me...
