This is an advanced PC device that is capable of testing the PC computers with different types of CPUs, including ALL series of previous and latest Intel / 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 (LPC 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 provide the code output function of PCI, LPC or PCI-E. This is not a problem with our diagnostic card. Many customers want to read the code through LPC or PCI-E. KQCPET6 V8 intelligent diagnostic card. Bluetooth transmission to the phone display (code, meaning and processing method in the "Qiguan easy to use diagnostic card" APP automatically intelligent matching); no longer need manually enter the code into phone. can be partitioned (by wall to view code or diagnostic results)Diagnostic desktop, laptop, mobile phone, a series of USB smart devices (such as home smart TV, car audio, industrial USB devices, etc.) ; in addition to PCI, PCI-E, LPC, MINIPCIE, EC USB interface diagnostic functions, add M2 (multiple interfaces) and mSata interface diagnostic functions A: Desktop test card B: Notebook diagnostic card color: red material: plastic Diagnostic desktop, laptop, mobile phone, a series of U
