The memory tests in toolstar®testLX and toolstar®testWIN offer you the option of using up to 7 subtests to use the device's entire free RAM testing. The different subtests simulate a wide variety of loads and access patterns in order to find every memory error. The memory tests are regularly updated and expanded.
Information about the main memory (RAM)
- Memory addresses
Shows under toolstar®testWIN the total size of the installed RAM in MB. Under toolstar®testLX a list of the memory areas reported by the system - the available” are normal RAM that can be tested; “reserved” are BIOS ROM areas (which cannot be tested, nor the few KB that have special meaning on ACPI systems); “Hardware” are areas occupied by hardware components (e.g. PCI cards). - Windows memory status (only toolstar®testWIN)
Windows Memory Status shows you the hardware and software information about general memory usage. This includes physical memory, utilization and information about the swap file. - Memory modules
A list of all recognized available slots and their occupancy. If the slot is occupied by a bar, you will see, among other things, the information about the memory bar (size, type, location, cycle, manufacturer, part number, serial number). - SPD-EEPROM information
Information about the SSPD-EEPROM information can be found here: To the article. - Speed
Speed shows the memory throughput in MB/s for read, write and arbitrary accesses using up to four different methods - CPU DWord transfers affect most general programs, streaming (SSE) shows the maximum speed for specially adapted applications.
The individual test options / memory tests
- Addressing (Very fast, linear)
- Chess board pattern
- Windows mode (simulates a Windows installation)
- Complementary bits
- Running bits
- Huge complements
- Distributed access (slower, distributed)
Hints and tips
- Duration and length of the individual memory tests
The further you go down the list, the longer the tests take. Addressing is by far the fastest test and distributed access is the slowest. However, each test finds different errors. - Memory test when booting Linux
With toolstar® testLX you have the option of selecting a kernel with memory test in the boot menu. A memory test is carried out during booting. This tests the memory area into which the Linux kernel will write. If an error occurs, this will be reported to you in toolstar®testLX within the Memory menus are displayed. In addition, the kernel automatically writes itself to a different area so that you can start and test from the beginning even on devices with defective memory areas. - Memory tests with toolstar®testWIN in the installed Windows
The free memory areas can also be tested in the installed Windows. However, memory occupied by applications and the operating system cannot be tested. Try to close as many programs as possible so that a large area can be tested. - Memory tests with toolstar®testWIN within Windows®PE/RE
Significantly more RAM can be tested under Windows®PE/RE than within an installed Windows. This allows you to bypass some of the limitations of an installed Windows and access the hardware more directly. Maybe our free toolstar®PEBuilder is interesting for you?
An error was not detected! What can I do?
Hardware errors are not always easy to diagnose. You have the best chance with endurance tests/automation scripts. It may well be that certain errors only appear after a certain amount of time or under certain thermal conditions. If the error does not occur even after long testing and various variations, but is relatively certain to exist, you can contact Support. After consultation, we are happy to accept defective memory bars in order to further improve our memory tests and also find this specific error.
