When troubleshooting computer issues, one of the primary systems we check is the computer’s memory (RAM). It’s a critical component that, when faulty, can lead to numerous performance issues or system crashes. To diagnose potential memory problems, we have access to different tools such as Windows Memory Diagnostic and Memtest86. These diagnostic tools are designed to identify issues by running a series of tests on the computer’s RAM.
Windows Memory Diagnostic is a built-in tool for Microsoft’s Windows operating systems, easily accessible from within Windows 10 and Windows 11. It provides a convenient way to perform a basic check of your system’s memory. On the other hand, Memtest86 is a third-party software known for its thorough testing process. It can be booted from a USB drive and operates outside of the Windows environment, which allows it to test memory more exhaustively. The choice between these tools often depends on the depth of analysis required and personal preference in maintaining system health.

Understanding Memory Diagnostics
Within this section, we’ll discuss the crucial aspects of memory diagnostics, focusing on the what, why, and common symptoms associated with memory-related issues in computing environments.
What Is RAM?
Random Access Memory (RAM) is a critical component in computers and other devices, acting as the main short-term data storage. It stores the information your computer is actively using so that it can be accessed quickly. The more RAM your computer has, the more data it can handle at once, which generally increases the system’s responsiveness.
Significance of Memory Testing
Testing RAM is essential because it can become faulty, leading to various system errors. Running a RAM test is a troubleshooting step we can take to determine if memory errors are causing system instability, such as crashes, blue screens of death, or system freezes. Accurately identifying faulty RAM is necessary to prevent data corruption and ensure the reliability of your system.
Common Memory-Related Errors
We’ve all seen our computer crash or suddenly reboot. These disruptions are often due to memory errors, which can range from minor annoyances to major data losses. Memory errors can manifest as:
- System crashes: Unexpected shutdowns or restarts
- Blue Screen of Death (BSOD): A critical error screen displayed by the Windows operating system
- System freezes: When the computer becomes completely unresponsive
- Data corruption: Incorrect or garbled information
Correct diagnosis and troubleshooting of these errors are necessary to minimize the risk of long-term damage to both hardware and data integrity.
Comparing Diagnostic Tools
When it comes to testing RAM for errors, we come across several options, but today, we’re focusing on Windows Memory Diagnostic and Memtest variants. Both serve a critical role in maintaining system stability by detecting memory issues.

Execution of Memory Tests
In our examination of memory testing, we’ll explore the actual execution of the Windows Memory Diagnostic tool, the usage of Memtest and Memtest86+, and the nuances involved in deciphering the results of these tests.
Running Windows Memory Diagnostic
When we consider Windows Memory Diagnostic, it’s worth noting that it’s a built-in tool within modern versions of Windows, offering a convenient first line of defense against RAM issues. To initiate a test, we’d normally access it via the Start Menu; simply type ‘Windows Memory Diagnostic’ and select ‘Restart now and check for problems.’ The utility then restarts Windows and tests the RAM, which can reveal potential issues with the DDR4, XMP profiles, or other memory modules installed.

- Select ‘Restart now and check for problems’
Using Memtest and Memtest86+
Booting from a USB drive or CD image, Memtest86 and Memtest86+ are thorough, stand-alone memory testing software programs. They both must be prepared on a separate disk or USB flash drive – a straightforward process involving tools such as mtinst.exe for Memtest86 and creating bootable media for Memtest86+. Memtest86+ is an open-source continuation, which is compatible even with Secure Boot enabled, crucial for newer systems.

| Create bootable USB/CD using mtinst.exe | Requires creating bootable media |
| Secure Boot compatible | Open-source, may lack Secure Boot compatibility |
Interpreting Test Results
After running these tools, interpreting the test results accurately is crucial. Windows Memory Diagnostic will automatically restart Windows after completion and log the results in the Event Viewer which we can check upon booting. We expect to find records under the system log, filtering for ‘MemoryDiagnostics-Results’ to spot any potential memory errors or signs of corruption. On the other hand, Memtest programs will present results on-screen, highlighting any memory errors across multiple DIMMs. It is important for us to carefully review the information provided to determine if further action is needed.

Troubleshooting and Resolution
When it comes to RAM issues, identifying the culprit is only part of the solution. In this section, we’ll guide you through steps to address detected issues, offer preventive tips, and highlight considerations for computer builds.
Addressing Detected Issues
Memory Error Prevention Tips
To minimize RAM-related troubles:
- Always opt for reliable and tested memory brands known for robust performance.
- Keep your system cool to prevent overheating, which can lead to memory errors.
- Regularly update your system’s firmware and BIOS to ensure optimal hardware compatibility.
- Conduct routine memory diagnostics to catch and address issues early.
Considerations for Computer Builds
When building a computer, consider memory right from the start:
| Compatibility | Scalability | Quality |
| Ensure the RAM is compatible with the motherboard and CPU. Check the QVL (Qualified Vendor List) for tested memory models. | Select a motherboard with enough DIMM slots for future RAM upgrades. | Choose RAM with lifetime warranties and support for peace of mind. |
Select RAM known for fewer errors, and consider error-correcting code (ECC) memory if your workload demands the highest level of data integrity. Lastly, balance RAM speeds with your CPU’s capabilities to avoid potential bottlenecks and maximize the performance of your applications.
