Memtest86 finish after 4 passes.

[sew333]

Hi. I am using memtest86 v.6.0 ( without + ) and after 6 hours i get message: Test is finished. Please press any button to continue. In main screen there was 4 \ 4 passes. And after that there was report after finished test. Is this normal?
Why its stopping ? I was thinking that MemTest keeps running for as long as you let it run.
Any suggestion?
