As MemTest runs off of the CD when you choose to boot your system with it for a memory test, all testing data is run in system memory only. So, the only way to see whether your memory is good or not is to run the program by using the CD. Windows is not running when MemTest is running. Windows does not even know MemTest is running, in fact, when you are running it. (MemTest runs outside of Windows)

No data is written to your hard drive, so no log will be produced.

[EDIT:] Don’t change any settings within MemTest. Leave them the way they are.

See attached picture below as to what to expect:

Any memory errors found will show up as bright red letters at the bottom of the blue screen. You can’t miss these errors when they show up. Allow the MemTest Program to run overnight. It will report it has done ‘X’ number of passes. If no errors are found, you can assume with reasonable certainty that your memory is good, and it is not bad or defective memory that is causing your blue screens.
