Comments on: Clear Indications of Bad Memory or Dimm Socket http://www.terminally-incoherent.com/blog/2007/07/19/clear-indications-of-bad-memory-or-dimm-socket/ Utterly random, incoherent and disjointed rants and ramblings...

Couldn't find that disk here at work, so I downloaded the <a href="http://oca.microsoft.com/en/windiag.asp" rel="nofollow">Microsoft Online Crash Analysis memtest tool</a> which seems to do the trick... and I just never bothered finding the other disk :) I don't know whether the MS one is an excellent tool or just an average one, but it seems to have worked fine for me so far.

I think I have one or two in my toolbox, but I'd love to hear what you use. So, can you recommend any good memory testing tools?

I've had computers that didn't have a pattern to their failure - might not make it past POST one time, the next it might work fine, the next Windows might freeze, the next one application exits with an unusual error, etc - which came good by replacing the RAM. Also try a memory tester - since I found out about memory test bootable CDs, I haven't had a stick of bad memory that wasn't detected by the CD. Saves having to pull a 'puter out of it's nest of cables and whatnot. Another time to suspect bad memory is when the computer is suffering random syptoms with no rhyme or reason.

I put it in a box labeled BAD RAM. I always figure I will use it for something cool. Haven't figured what I'd do with them. I also have around 20 bad laptop hard drives stacked up on the shelf behind me. Partly because I don't feel like figuring out the proper way of disposing them with regards to confidentiality policies and etc. Every once in a while I take one of them apart to get the cool magnets and the shiny platter out of it. I have several of them hinging off my lamp at work. :) <strong>Starhawk</strong> - You may or may not get memory read errorsIf the DIMM socket on the motherboard is going bad, you will likely see behavior like the above.

But i would have expected memory read write errors so thanks for the info gives me a clue to know what to look out for.

Too many people will see it in the trash and take it back out, especially fellow admins. I can't tell you the number of times I have had to troubleshoot the same issue only because some admin tried to help save money by picking through the trash. Same goes with bad network patch cables . . . cut the ends off for added insurance that it will never reappear in your stockpile. Don’t forget to destroy the bad memory after you confirm it’s death.
