Hi there! I'm running memtest86 in one of my laptops to discard RAM failure, so far, after 6 hours and 2 and half passes, no errors popped out... I've read some people tat says that the first 2 passes are crucial to find errors, while the rest are less subtle or something like that... what do you reccomend, the machine I'm testing has 16 gigs of RAM, and honestly, I don't know if going too far as testing for more than 8 hours will harm my system, and I need it for work. What are your thoughts on the matter? Thanks in advance. Cya!
