Passmark Memtest86 Pro Keygen is an advanced memory diagnostic software used to thoroughly test the RAM (random access memory) in computers for errors. This bootable program runs comprehensive scans to detect faults in memory that can cause crashes, blue screens, data corruption, and other system instability issues.
What is Memtest86 Pro?
Memtest86 Pro is the premium paid-for version of the popular free memory tester, Memtest86. While Memtest86 is capable of testing RAM, the pro version offers a more robust feature set focused on advanced memory diagnostics.
Some key capabilities unique to Download free Passmark Memtest86 Pro:
- Comprehensive Test Suite: Runs 13 different RAM test patterns to expose a wide range of errors
- Faster Scanning: Multi-threaded testing utilizes all CPU cores for quicker test times
- Error Debugging: Detailed error reports pinpoint failed RAM stick, channel & errors to aid troubleshooting
- Long Duration Testing: Ability to scan over many hours/overnight for more rigorous testing
At its core, Memtest86 Pro assesses memory integrity by writing various test patterns to RAM and reading it back to check for discrepancies. Any errors indicate flaws in RAM that can manifest as operational issues like crashes and blue screens. It will also detect errors caused by overclocked memory or CPUs that are unstable.
How Memtest86 Pro Differs from Memtest86
Memtest86 Pro builds on the capabilities of the free Memtest86 tool with premium features focused on robust memory diagnostics:
Feature | Memtest86 | Memtest86 Pro |
---|---|---|
Test Patterns | 9 | 13 |
Testing Modes | Single Pass | Continuous, Customizable |
Max RAM Tested | 4 GB | >64 GB |
Error Debugging | Limited | Advanced Reports |
Boot Media Options | CD/DVD, USB | Bootable USB Drive |

Complete Suite of Memory Tests
Memtest86 Pro has an expansive built-in test library encompassing a wide spectrum of memory checks:
- Random Value Tests: Checks memory using randomized test patterns
- Compare Tests: Writes memory, reboots, then compares initial vs current content
- Moving Inversion Tests: Flips bits in moving patterns to find errors
- Block Move Tests: Manipulates memory blocks to check usability
- And 8 more patterns to stress test RAM…
Running the gamut of these tests ensures no RAM defects slip through undetected.
Multi-Threaded Testing for Faster Execution
Unlike single-threaded Memtest86, the Pro version splits testing across all available CPU threads.
By harnessing multiple cores, complete scans can run significantly faster:
System | Cores/Threads | Est. 3-Pass Runtime |
---|---|---|
Older 2 core CPU | 2 threads | 4.5 hours |
Modern 6 core CPU | 12 threads | 1.5 hours |
Faster test times allow more rigorous memory vetting.
Advanced Error Reporting and Debugging
Memtest86 Pro provides highly-detailed error logs that aid diagnosing faults:
- Pinpoints exact RAM module and address with failure
- Shows test pattern that exposed issue
- Indicates severity level of errors
With precise failure data, users can quickly identify and replace bad memory components instead of troubleshooting blindly or replacing good hardware.
Long Duration Testing
While Memtest86 is typically run for only a few passes, Memtest86 Pro is designed to scan over extended periods to uncover marginal memory integrity issues.
Testing over 10+ hours or overnight allows drilling down on stability problems caused by:
- Borderline unstable overclocked RAM/CPUs
- Intermittent faults in modules
- Heat related issues
Catching these under marginal conditions prevents ghost errors plaguing overclocked systems.

Recommended System Requirements
Before deploying Free download Passmark Memtest86 Pro Keygen for scanning, ensure your system meets these suggested requirements:
RAM: Systems should have at least 128 MB of RAM, but 1 GB or higher is recommended for more thorough testing.
Operating Systems: Memtest86 Pro runs from a bootable USB drive, so it can test all OS types by booting outside the installed OS environment.
Motherboards: Works with most modern Intel and AMD motherboard models. May have issues with some server boards.
CPU: Any x86 or x64 processor. Multi-threaded CPUs enable faster test times.
BIOS: System BIOS should support booting from USB drives, have OS Optimized Defaults applied, and memory settings set to factory specs.

When and Why to Use Memtest86 Pro
There are several situations that warrant deploying Passmark Memtest86 Pro Free download to diagnostics system memory for errors:
- Random computer crashes/freezes – Failing memory that gets corrupted randomly can cause operational instability and crashes that seem to happen out of the blue. Scanning with Memtest86 Pro can check for memory faults causing the crashes.
- New RAM installation – When installing new RAM modules, it’s strongly advised to test them thoroughly with Memtest86 Pro to validate stability at XMP speeds, compatibility with the motherboard, and to detect any DOA modules needing return/replacement instead of troubleshooting endlessly.
- Long term aging computer – Systems more than 2 years old that have never had RAM tested should run preventative Memtest86 Pro checks. This might catch intermittent faults creeping in as hardware ages before they become more serious.
- Overclocked memory/CPU stability verification – Applying RAM overclocked profiles like XMP or manually overclocking memory requires stability testing with Memtest86 Pro. You’ll also want to test overclocked CPUs that push RAM past stock speeds. Memtest86 Pro error-free runs indicate the overclocks are solid versus general stress testing utilities that often miss memory related crashes.
Bottom lineāif you’re encountering any system crashes, errors, or other odd behavior, one of the first troubleshooting steps should be scanning memory with Memtest86 Pro. Finding RAM issues early saves endless frustrated troubleshooting of other hardware that ultimately isn’t faulty.
Step-by-Step Guide to Using Memtest86 Pro
While incredibly comprehensive under the hood, Full version crack Passmark Memtest86 Pro Keygen is designed to be easy for anyone to use for testing RAM in just a few steps:
1. Create Bootable Memtest86 Pro USB Drive
First, grab the install files from our site and create bootable media:
- Download Memtest86 Pro install files
- Insert a spare USB flash drive (2GB or larger)
- Use software like Rufus to transfer files and make drive bootable
- Change BIOS settings to enable USB booting as first device
Having USB installation media makes deployment fast and convenient vs optical discs.
2. Configure BIOS Settings For Testing
To test memory under optimal conditions, configure the motherboard BIOS appropriately:
- Load Failsafe Defaults: Removes any instabilities caused by overclocks
- Set Memory To Factory Specs: Run at standard JEDEC speeds to start, 2133 MHz for DDR4
- Disable Memory Fast Boot: Completely resets memory when rebooting between passes
This eliminates other variables outside RAM that might cause test failures.

3. Select Your Target Test Parameters
Upon booting from the newly created USB media, Passmark Memtest86 Pro Download free lets you define test duration or number of passes. Options include:
- Standalone Single Pass: Quick functional check that saves logs to USB drive.
- Set Number of Passes: Choose a pass count then begin scanning, like 5+ passes over 6+ hours for rigorous testing.
- Continuous Testing: Scans indefinitely for days/weeks until stopped manually. Great for burn-in.
For initial troubleshooting, start with 5 complete passes to thoroughly stress memory.
4. Begin the RAM Test Process
Clicking Start Testing initiates the intensive memory scanning process using Memtest86 Pro’s comprehensive built-in pattern library to hammer through the target pass count scanning for any weaknesses.
As testing progresses, the main display outputs real-time test duration, completion percentage, errors detected, test performance, overall pass/fail, and other telemetry.
5. Evaluate Test Logs and Error Reports
After scanning finishes, refer to the test logs and error details:
- Error Severity: Indicates warning or more serious failures
- Failure Details: Identifies specific RAM module location, address, and test pattern causing errors
- System Info: Configuration summaries aid troubleshooting
For warnings or failures, begin inspecting modules for faults, cleaning contacts, trying replacements, warranty returns/RMAs.
While no errors indicate stable memory suitable for overclocking and long term reliability.
