DDR2 and DDR3 instructions for use with light tester
1. The DDR2 test method:
The DDR2 test is divided into two parts, the first part of the test for LED lights, use the battery or ATX20 power can be, will tester inserted into the mainboard DDR2 slot (note: the power CONNECTOR on the main board of the various from removed), press tester switch, among observation two rows of LED lights, all light and brightness is OK, such as LED not bright or high brightness is corresponding signal for open or short circuit, the second part is the current test, can only be used ATX20 power, will ATX20 insert tester. A multimeter to dc 200 MA file out, whose hands inserted into the red TP1 tester hole, the black one on the tester anlaogue display measurement test point signal current.
2. DDR3 test method:
DDR3 only need to use LED lamp test, use the battery and ATX20 power can be, will tester inserted into the mainboard DDR3 slot (note: the power CONNECTOR on the main board of the various from removed), press the switch on the tester, observe three rows of LED lights, all point (except some motherboard, a portion of the different LED not bright, CLK2, CLK2 only in the test to light, MA15 DDR2, DQS8, according to design DQS8 judge) and bright and brightness is OK, such as LED not bright or high brightness is corresponding signal for open or short circuit.
Suggest using DDR2 and DDR3 and protect notch protect notch DDR2 and DDR3 protection of gold finger.
Description:
DDR 2 & DDR 3 Memory Slot tester is used to test open circuit or short circuit of PC mainboard memory slot. When the mainboard generate alarm for memory failure, while the memory would not work or when the mainboard work well and the memory size does not show enough, It can be used to test the error.
Remark: when testing motherboard memory slot, most repairers only test using a very expensive ram machine to diagnose it. This tester is suitable for some inital checking for the slot instead this kind of complex equipment. It is difficult to repair it successfully for using multimeter to test every slot footpin of motherboard. By using our tester, it is easy and save time to see the open circuit or short circuit point through the signal on board
It is powered by CR2032 or 20 pin power plug, it does not include the CR2032 battery.
