Embodiment Construction
[0024] see figure 1 , is a computer motherboard testing device 100 provided in an embodiment of the present invention, and is used to test whether a computer motherboard 200 can work normally. The computer motherboard 200 includes a plurality of memory channels 210 and a CPU 250 . Each memory channel 210 includes a plurality of slots 211 for inserting memory. The multiple combinations of the slots 211 include combining the slots 211 in each memory channel 210 with the slots 211 in other memory channels 210 respectively, and combining multiple slots 210 in each memory channel 210 Combine separately. In this embodiment, the number of memory channels 210 is two, and the number of slots 211 in each memory channel 210 is two, so there are combination of slots. The memory channels 210 and the number of slots 211 in each memory channel 210 are not limited to this embodiment. Corresponding to different combinations of slots, when the memory is inserted into the corresponding slo...

The invention relates to a computer main board testing device, which is used for testing a computer main board. The computer main board comprises a CPU (central processing unit) and a plurality of internal memory channels. Each internal memory channel comprises a plurality of slots. The computer main board testing device comprises a plurality of memories which are plugged in the slots, at least one switch chip, a microcontroller and a testing module. The at least one switch chip comprises a plurality of input pins which are electrically connected with the slots, a plurality of output pins which correspond to the input pins and are electrically connected with the CPU, and a control pin. The microcontroller is used for storing various combination ways of the slots, giving a serial number to each combination way, and transmitting control commands to the switch chip through the control pin according to the sequence of the serial numbers so as to control the slots in the slot combination way corresponding to the current serial number to be connected with the CPU and other slots to be disconnected with the CPU. The testing module is used for judging whether the CPU can control the corresponding memories to work in a correct working mode or not in each slot combination way. The invention additionally relates to a computer main board testing method.
Description
technical field [0001] The invention relates to a computer main board testing device. Background technique [0002] Since the computer motherboard includes multiple memory channels, and each memory channel includes multiple slots for inserting memory, the combination of slots of different memory channels and slots in the same memory channel There are many kinds. There are many working modes of the memory, and each working mode corresponds to a corresponding combination mode, and the working mode is different when the memory is inserted into the slots of different combination modes. In the production process of the computer motherboard, it is necessary to test whether the CPU can control the memory inserted in the slot corresponding to the combination mode when the memory is inserted in the slot of each combination mode. Work in the corresponding working mode. The current practice is that the operator manually inserts the memory into the slot of each combination mode and s...
