[Question] How to test RAM to determine if it's bad?


Hello members,

I got some RAM from a friend and the RAM might be faulty but he wasn’t sure if it was it was the motherboard he was using or the actual RAM. What is the best way to test the RAM?

Memtest is probably the best tool, but you do have to watch it closely if you want to see all of the errors. In most cases with bad ram, it will spit out a bunch of error codes and you can use that for confirmation. In rare cases, it won’t show any errors, but you will notice random pauses and characters going bad(like 0’s turn into squares), or Memtest will flat out crash(from the bad RAM), but since the test is so long you won’t notice it(or get any error codes from the crash).
