Desktop Memory System: open circuit or connection. A pin, trace, socket or component no longer carries its required signal.

The distinguishing clue

One rail or channel is absent while neighbouring stages work.

Checks before an assessment

Record the exact memory-kit and motherboard models from existing records, plus any capacity or POST message. Do not force modules or repeatedly swap them during power-on tests.

Stop point: Forcing a module into a damaged or incorrectly keyed slot can ruin both parts.

Workshop confirmation and repair

Device-level check: Compare known modules and slots, inspect socket condition and review supported timings.

Targeted check: Trace continuity and signal progression with power isolated where required. If confirmed: Repair the open path and its mechanical or thermal cause.

Repair boundary: Repair the confirmed slot, channel, board or compatibility fault.

Related cause to rule out

When the fault changes with temperature or chassis flex, also consider Desktop Memory System: intermittent solder joint before choosing a repair.

Checks after the work

After repair or replacement, check each channel, full capacity, memory test and sustained workload.
