"Safe" memory testing
I would like to test my RAM with the memtest86 program. Some of the
Readme.txt discusses "safe" memory testing. Does this mean that the memory test routines could possibly physically harm the RAM in some way, or does this mean that the program can run without crashing the computer, or does this mean something else? (partial quote from Readme.txt, note second paragraph...) .. .. .. The BIOS in modern PC's will often reserve several sections of memory for it's use and also to communicate information to the operating system (ie. ACPI tables). It is just as important to test these reserved memory blocks as it is for the remainder of memory. For proper operation all of memory needs to function properly regardless of what the eventual use is. For this reason Memtest86 has been designed to test as much memory as is possible. However, safely and reliably detecting all of the available memory has been problematic. Versions of Memtest86 prior to v2.9 would probe to find where memory is. This works for the vast majority of motherboards but is not 100% reliable. Sometimes the memory size is incorrect and worse probing the wrong places can in some cases cause the test to hang or crash. .. .. .. |
