Memtest86 Pro v11.0.1000 ISO-USB Multilingual
MemTest86 Pro is a powerful memory diagnostic software tool designed to test the reliability and stability of computer memory. Developed by PassMark Software, MemTest86 Pro is widely recognized as one of the most accurate and comprehensive memory testing utilities available today.
At its core, MemTest86 Pro is a program that runs a series of tests on a computer’s RAM (random access memory) chips in order to identify any potential errors or faults that may exist. These tests are designed to thoroughly examine the memory subsystem of a computer, including the RAM modules, the motherboard’s memory controller, and the CPU’s integrated memory controller.
One of the key features of MemTest86 Pro is its ability to detect even the most subtle memory errors that can go unnoticed by other diagnostic tools. The program uses several advanced algorithms and techniques to perform a deep analysis of the system memory, including exhaustive bit-level analysis, pattern tests, and data integrity checks.
In addition to its comprehensive testing capabilities, MemTest86 Pro also includes a range of powerful reporting and logging features, enabling users to easily track and analyze the results of their memory tests over time. Test results can be saved to disk or printed out for further analysis, making it easy to identify patterns or trends in memory errors over time.
Another notable feature of MemTest86 Pro is its support for UEFI firmware, which enables the program to boot directly from modern UEFI-based systems without the need for legacy BIOS emulation. This allows users to run memory tests on the latest hardware platforms using the most up-to-date firmware interfaces.
MemTest86 Pro also supports a variety of different memory architectures and technologies, including DDR4, DDR3, DDR2, and DDR SDRAM, as well as ECC and non-ECC memory modules. This broad compatibility ensures that the program can be used with a wide range of computer systems, from consumer-grade desktops and laptops to high-end enterprise servers.
To use MemTest86 Pro, users simply need to download the program and create a bootable USB drive, which can then be used to boot the system directly into the memory testing environment. The program includes an easy-to-use graphical user interface that guides users through the testing process step-by-step, making it accessible even to beginners.
In conclusion, MemTest86 Pro is a powerful and versatile memory diagnostic tool that provides users with a comprehensive set of features for testing the reliability and stability of computer memory. Its advanced algorithms, support for modern UEFI firmware, and broad compatibility with different memory architectures and technologies make it a go-to choice for system administrators, IT professionals, and power users alike. Whether you’re looking to troubleshoot a specific issue with your computer’s memory or simply want to ensure that your system is running at peak performance, MemTest86 Pro is an essential tool for any serious computer user.
There are many good approaches for testing memory. However, many tests simply throw some patterns at memory without much thought or knowledge of memory architecture or how errors can best be detected. This works fine for hard memory failures but does little to find intermittent errors. BIOS based memory tests are useless for finding intermittent memory errors.
RAM chips consist of a large array of tightly packed memory cells, one for each bit of data. The vast majority of the intermittent failures are a result of interaction between these memory cells. Often writing a memory cell can cause one of the adjacent cells to be written with the same data. An effective memory test attempts to test for this condition. Therefore, an ideal strategy for testing memory would be the following:
- Write a cell with a zero.
- Write all of the adjacent cells with a one, one or more times.
- Check that the first cell still has a zero.
It should be obvious that this strategy requires an exact knowledge of how the memory cells are laid out on the chip. In addition there are a never ending number of possible chip layouts for different chip types and manufacturers making this strategy impractical. However, there are testing algorithms that can approximate this ideal and MemTest86 does just this.
The standard for memory diagnostics
– Boots from a USB flash drive to test the RAM in your computer for faults.
– Utilizing algorithms that have been in development for over 20 years.
Unreliable RAM can cause a multitude of problems. Corrupted data, crashes and unexplained behaviour.
Bad RAM is one of the most frustrating computer problems to have as symptoms are often random and hard to pin down. MemTest86 can help diagnose faulty RAM (or rule it out as a cause of system instability). As such it is often used by system builders, PC repair stores, overlockers & PC manufacturers.

What’s NEW:
- New Features
- Added new configuration file parameter CHECKMEMSPEED for verifying whether the configured memory speed is consistent with one of the SPD profiles or an arbitrary minimum speed specified by the user. If this check fails, an error message is displayed and the memory test will not start. This is useful for confirming that the memory tests are carried out at the maximum speed supported by the RAM.
- Added new configuration file parameter TCPREQUESTLOCATION for specifying the URL request path (and cloud API key) for PassMark Management Console integration
- Added new configuration file parameter TCPGATEWAYIP for setting the default gateway route IP address to allow for connections outside the local network for PassMark Management Console integration
- Added new configuration file parameter SPDREPORTEXTSN for specifying whether to use the module’s extended, 18-digit serial number or standard 8-digit JEDEC serial number in reports. The extended serial number encodes additional manufacture information (including the manufacture ID, date and location) and is more likely to match the serial number printed on the label of the RAM module.
- Added new configuration file parameter DISABLESPD for disabling SPD collection. This is a workaround to prevent throttling of memory speeds, which results in increased test times. This occurs when reading SPD data interferes with the chipset’s Closed-Loop Thermal Throttling (CLTT) mechanism. CLTT is used on a small number of server motherboards to reduce the speed of RAM access when temperatures are too high. But in this case the throttling was seen to be incorrectly activated, due to what we suspect is a BIOS bug.
- Added new configuration file parameter TSODPOLL to enable/disable polling of DIMM temperature sensors (if available). Polling is on by default.
- Preliminary address module decoding support for Intel Meteor Lake/Arrow Lake chipsets. This can help pinpoint the physical location of a memory error.
- Support for collecting memory timings periodically during the test session. When the test completes, the lowest/highest memory speeds are reported. Some motherboard vary timings in a dymanic fashion.
- Added support for reporting AMD EXPO profiles in DDR5 SPD. EXPO allows for running the RAM at faster than normal speeds without manual overclocking. As always, MemTest86 never changes the BIOS settings. This is just a change to report what profiles are available.
- Fixes/Enhancements
- Added TLS (encrypted data) support for PassMark Management Console integration. This is only used when sending test results to the central database for record keeping.
- Added DNS support for PassMark Management Console integration
- Added support for new DDR5 form factors “CDIMM”, “CSODIMM” and “CAMM2” for CHIPMAP configuration file parameter. This is to support the new clocked (CUDIMM/CSODIMM) and compact (CAMM2/LPCAMM2) DDR5 form factors supported by newer chipsets (eg. Intel Arrow Lake).
- Increased maximum string length of chip labels to 6 for CHIPMAP configuration file parameter. This is to support longer names used in CUDIMM, CSODIMM and CAMM2 component labels such as “DAR0B0”.
