Test plate with diodes for DDR4 memory arrays

Allows you to test whether all contactors on a DDR4 strip are in good condition and active. Instant visual test thanks to a tray of LEDs.

Description:

The plate features two ports for DDR 4.
For its operation, the tester needs to be powered, you can do so either from a USB power supply (cord supplied), or by inserting a CR2032 battery in the slot provided. A switch allows you to select the type of power supply chosen.
Once a strip has been inserted, you shouldn't notice any anomalies; all the diodes should light up in the same way.
A flashing diode indicates a false contact,
An unlit diode indicates an open circuit,
A highlighted diode will signal a short circuit.
No special skills are required, just look at the diodes!.

Note that this tester will not test for possible errors in the RAM, just the quality of its contacts.
