How do I check for a possible cause ‘app or driver memory leak’?

If there is no change in the first step, compare in order until ‘Running memory diagnostics’. If symptoms disappear immediately after certain actions or the conditions for their occurrence change, this can be an important clue in narrowing down the cause.

Memory keeps growing when you leave certain programs running for a long time: When do you need a professional check?

Even if you follow the above solution steps in order, if the memory leak symptom repeats or hardware abnormal signals such as a burning smell, abnormal noise, overheating, or failure to recognize parts appear, we recommend backing up important data and having a professional inspection.

An app's memory usage keeps increasing over time

Q: What should I check first if I see symptoms of a memory leak?

First, proceed with the ‘Turn off XMP/EXPO and memory overclocking and check’ step. Memory profiles use higher speeds than rated and may be unstable depending on system combination. We recommend that you avoid changing multiple settings at once and check to see if your symptoms change after each step.

Among performance issues, “memory leak” symptoms may be related to app or driver memory leaks, browser extensions, or background processes. After returning memory settings such as XMP/EXPO to default, perform diagnostics and module/slot cross-testing.

How to solve

Please check them in order from the top. If the issue is resolved, you do not need to proceed to the next step.

Disable XMP/EXPO and memory overclocking and check

Memory profiles use higher speeds than rated and may be unstable depending on system combination.

Difficulty Moderate time 10-20 minutes cost 0 won

1Disable XMP/EXPO in BIOS.
2Leave the memory speed as Auto or default.
3Try using it enough to see if the symptoms disappear.

confirmation point

After these steps, see if the “memory leak” symptoms decrease or disappear. If there is no change, check for possible app or driver memory leaks in the next step.

Running memory diagnostics

RAM errors can be confirmed by repeated crashes, blue screens, and file corruption.

Difficulty Moderate time 30 minutes to several hours cost 0 won

1Run Windows Memory Diagnostic or Trusted Boot Memory Check.
2If an error occurs even once, check each module and slot individually.

Recheck RAM installation status

If the module is not fully inserted or has poor slot contact, capacity loss or POST failure may occur.

Difficulty Advanced time 15-30 minutes cost 0 won

1Turn off your PC completely and unplug the power cable.
2If you have experience working inside a PC, remove and reseat the RAM until both retaining clips lock.
3Check the recommended slot order on your motherboard.

Cross-test one by one or slot by slot

This will help you distinguish between bad modules and bad slots.

Difficulty Advanced time 30 minutes or more cost 0 won

1If there are multiple modules, test them one by one.
2Check other slots for modules that appear to be normal.
3If the error is traced to a specific module, suspect its RAM.

Check BIOS updates and memory compatibility

In particular, the new CPU/DDR5 combination improves memory compatibility with BIOS updates.

Difficulty Advanced time 20~40 minutes cost 0 won

1Check your motherboard manufacturer's support page for BIOS changes.
2Please refer to the memory QVL and CPU support list.
3Avoid power loss during BIOS update.

Frequently Asked Questions

We've put together a list of things we frequently check regarding this issue.

Related issues

If the symptoms do not match exactly, please check the issue below.

Performance

Memory usage continues to be high

If “high RAM usage” repeats, it is better to narrow the scope to program overruns and memory leaks rather than changing several settings at once. After returning memory settings such as XMP/EXPO to default, perform diagnostics and module/slot cross-testing.

Memory

RAM errors cause random app or Windows crashes

When troubleshooting random programs and Windows crashing due to RAM errors, it's important to rule out the causes one at a time. Based on the “random crash” symptom, check for a defective RAM module or slot or XMP/EXPO instability, then proceed to the next step. After returning memory settings such as XMP/EXPO to default, perform diagnostics and module/slot cross-testing.

Memory

The problem is that the installed RAM is not recognized at all.

If “RAM not recognized” repeats, it is better to narrow down the problem to poor RAM installation, slot or module problems rather than changing several settings at once. After returning memory settings such as XMP/EXPO to default, perform diagnostics and module/slot cross-testing.

Memory

Problem not booting after adding/replacing RAM

Among memory problems, the symptom of “No booting after changing RAM” may be related to memory training or poor installation. After returning memory settings such as XMP/EXPO to default, perform diagnostics and module/slot cross-testing.
