What can bad ram do?

[dario03]

My co-worker was wanting to throw some ram in his computer to see if it works. I told him that when overclocking if you go to far then it can damage the loader for Windows which can require a reinstall of Windows. I assume a bad ram chip could do the same, but am I correct?

bad ram usually just doesn't work or makes the comp unstable and prone for crashes. in my experience

just pure instability, or sometimes it just won't boot (like this system..)
