Product Content

DDR4 illuminated test card fully supports INTEL, AMD all motherboards DDR4 interface, can quickly and accurately test the motherboard various data and address lines open, short, use bright LED on and off to indicate that each bus and a control signal, replaces the traditional method of individually measured with a multimeter, easy to use, intuitive, it is an indispensable tool for maintaining computer motherboard.

Instructions for use:

1, will be equipped with a battery (CR2032,3V) Insert the battery holder and the test card is inserted in the corresponding model of the motherboard, the motherboard plug in CPU, press the switch on the test card, you can determine the open portion of the motherboard memory, short-circuit fault , such as a lamp is not lit, check whether the CPU socket and memory slots open or shorted to ground. If a special bright light, you will have to check whether the lamp short to power.

2, the tester can also be false load resistance card.

Precautions:

1, after repeated use, the tester dimming, because the tester battery voltage is not enough, ask the user to replace the battery.

2, various signals of this tester, because various manufacturers and chipset motherboard design, it may show a different part of the signal, maintenance personnel with the same control board can determine fault.

New laptop DDR3 lamp test instructions

Product synopsis:

This product for a generation notebook DDR3 test lamp upgrade the product, product comprehensive support laptop forward and reverse interface, it is to use leds light and destroy data to indicate the signals of opening address lines with short circuit, instead of traditional using a multimeter measurement method for them one by one, to repair it didn't turn on, don't show, don't read the fault of memory and so on the mainboard, maintenance is an essential tool notebook computer motherboard.

Instructions:

1, with the 3.3 V in tester (CR2032) battery, insert the corresponding notebook motherboard respectively of DDR3 memory each slot, mainboard don't have electricity, the bright and brightness lamp test consistent, signal lines that normal, if has the bright lights or very bright, indicating that this signal have open short-circuit fault, using a multimeter to further define the fault point. (note: all kinds of signals, because tester in each of the contractor the mainboard design and the different chipset, a part of the signal may show that the different, please maintenance personnel using the same motherboard control judge fault.)

2, memory pin the corresponding signal in the list below:
