1. [EASY TO USE] Install the battery on the tester, and test each memory slot of DDR2 and DDR3 motherboards without external power supply.
2. [ACCURATE INDICATION] LED lights show open and short circuits of data and address lines, perfect for repairing non-working motherboards.
3. [VERSATILE COMPATIBILITY] Supports both and motherboards with DDR2 and DDR3 interfaces.
4. [DURABLE CONSTRUCTION] Heat-treated for high hardness, ensuring long-lasting durability.
5. [RELIABLE TESTING] Easily identify motherboard faults, no need to test resistance with clear LED indicators.

Specification:
Features:
1. Supports for / motherboards with DDR2 and DDR3 interfaces without external power supply.
2. Use LED to indicate the open and short circuit of the data line address line, used to repair the motherboard that is not turned on.
3. Due to different motherboard design, some lights may not be lit. Can use the same motherboard to judge the fault.
4. When testing the motherboard of , as long as the lamp is fully lit, it means normal, no need to test the resistance of the address line.
5. Finished by heat treatment, it is high hardness and durable.

Instructions for use:
1. Install the 3V (CR2032) battery on the tester, test each memory slot of the corresponding DDR2, DDR3 motherboard. The motherboard does not have power, press the switch on the tester, the test lamp is all bright and the brightness is the same. The signal line is normal, if the light does not shine or special bright, this signal has open circuit short circuit fault. (Note: In the test for motherboard, motherboards do not connect the CPU and a variety of connection cards can be measured in the test for motherboards (such as 940 motherboard, AM2 motherboard, 1207 motherboard, 1366 motherboard), to plug in CPU, test light Will be bright.
2. In the test DDR2 motherboard, the address line no pull-up exclusion, all the lights all bright, that normal, if the pull-up exclusion, the address , only that exclusion no open, but also with the pointer Table to further determine whether the BGA address line open. (How to determine whether the pull-up exclusion, the pull-up exclusion generally are designed in the memory slot to the general There are several exclusion, one end connected to the address line, one end of the power supply)
3. Pointer table to determine the address line method: the pointer table is pulled to X1 that is one ohm of the stalls, black table pen then motherboard, measured with a red table pen, respectively, DDR2 address line measurement hole, address line resistance that BGA address Line without welding, such as a larger swing, indicating that there are BGA solderable PCB or broken wire failure.
