Allows you to test if all the contactors of a RAM slot are in good condition and active. Instant visual test thanks to a LED diodes tray. Compatibility: Any DDR Slot DDR SDRAM 2 (DDR2) or DDR SDRAM 3 (DDR3). Processing mode: - Insens a battery in the tester (battery not supplied but you can use the motherboard battery during the test!) Then position the tester on the port DDR to be controlled (one side DDR2, one side DDR3), - Press the small button located on the tester and view the diodes. All must have the same brightness: a diode too dark can point out an open circuit, while a too bright diode can point out a short circuit., No particular skill is required, just a finger is enough to press the button. The motherboard is not necessary to be fed to test the viability of contacts.
