This is an advanced PC device is capable of testing the PC computers with different types of CPUs, including ALL series of previous and latest / AMD / Cyrix CPUs. It can test the components of computer main board working or not and test the initialization of the system hardware, such as: System Chipset, CPU Initialization and Registration, HDD Controllers, System Cache, Extended Memory RAM, Keyboard/Mouse Controller, Sound and LAN Controller, Video Memory and Controller etc.Note: The diagnostic card is only an auxiliary tool, the purpose is to detect the motherboard failure through the code, but not all ports ( PCI-E PCI) have code output, which has nothing to do with the quality of the diagnostic card, the code is reserved by the manufacturer.The purpose is when the motherboard has a fault. The manufacturer can read the motherboard fault code information in some ways.There are many PCB motherboard manufacturers in the world. Each manufacturer of PCB motherboards is different, and each manufacturer open testing ports are different, Even some motherboards do not the code output function of PCI, or PCI-E. This is not a problem with our diagnostic card. Many customers want to read the code through or PCI-E.KQCPET6 V8 intelligent diagnostic card.
