ADATA DDR4 2133 8GB memory repair
ADATA DDR4 2133 8GB memory is damaged, replace 15 Ω drain resistor, and repair the fault.
Machine model: ADATA DDR4 2133 8GB
Fault phenomenon: the memory is broken
Maintenance process: the customer’s memory is broken, so it is replaced directly. The broken parts are still quite new. See the picture:

This kind of green bar has common failing, black 15 Ω,lighting cable buffer double drain resistance is very easy to break, this green bar 10 no booting, at least 6 of which are damaged by this small drain resistance.

Normally, the ground diode is 317 or so, until the second buffer resistance OverLoad is hit. After measuring the resistance of another section, there are 310 diodes, and things become very simple.
