This test is done sequentially with each available CPU. It can also be seen that caching, buffering and out of order execution will interfere with the moving inversions algorithm and make less effective. While it will help you determine which stick of RAM is causing you the problem, if your issue is a bad northbridge or perhaps a bad DIMM itself you won't be WARNING!: This is potentially dangerous, especially during boot.
Test 10: Modulo-X Every 20 locations, it writes a pattern (all 0s or all 1s) and writes the complement in all the other locations, then verifies. Run memtest with single chip at a time and try again. Have thoroughly dusted and have it sitting on 4 boxes of mac and cheese (the best use I've found for the stuff!) for air circulation. Booting v5 or later in UEFI All MemTest86 images supports dual-booting of v4 (BIOS) and v5 or later (UEFI), depending on whether your system is configured to boot in UEFI or

After you have done this, restart your computer. Test 5 [Moving inversions, 8 bit pat] This is the same as test 4 but uses a 8 bit wide pattern of "walking" ones and zeros.
Test 6 [Block move, 64 moves] This test stresses memory by using block move (movsl) instructions and is based on Robert Redelmeier's burnBX test.
