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, not all ports ( PCI-E PCI) have code output, which has nothing to do with the 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 diagnostic card. Many customers to read the code through or PCI-E. KQCPET6 V8 intelligent diagnostic card. Bluetooth transmission to the phone display (code, meaning and processing in the "Qiguan easy to use diagnostic card" APP automatically intelligent matching); no need manually enter the code into phone. can be partitioned (by wall to code or diagnostic results)Diagnostic desktop, laptop, mobile phone, a series of USB smart devices (such as TV, car audio, industrial USB devices, etc.) ; in addition to PCI, PCI-E, , MINIPCIE, USB interface diagnostic functions, M2 (multiple interfaces) and mSata new interface diagnostic functions A: Desktop test card B: Notebook diagnostic card color: red material: plastic Diagnostic desktop, laptop, mobile phone, a series of USB smart devices (such as TV, car audio, industrial USB devices, etc.) Interface Diagnostic:PCI,PCI-E, ,MINIPCIE, ,M2,mSata,USBinterface diagnosticfunctions password:1234 : Fit for desktop computer and laptop. An advanced computer motherboard CPU ram hardware diagnostic test card with motherboards stability test feature Latest 4-in-1 version with LCD panel extension connector An extra feature of quick test of the computer system stability Can work with/without CPU/RAM on board Come with extra (QG diagnosis) of testing the computers besides the Bios POST code Great for onsite technicians, computer admin and home/office personal uses Allows the users to test the hardware errors + testing the computer working stability in a matter of Package Contents: 1 x V8 intelligent diagnostic card set Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
