Memtest question

[Nocturnal]

I noticed that this unit here scanned with Memtest says there are no errors but it still shows bad memory type symptoms. I swapped out the memory and the issues are cleared up. Have you ever seen Memtest not catch bad memory?

How many passes did you have Memtest do?

I usually leave it running for 24hrs if I suspect something is amiss; it tends not to find anything if one leaves it for less time.

Use Tests #5 and #8 if you want to find errors faster.

 

[redbeard1]

Yes, a few times.

Yes. Memtest can only say that there /is/ a problem, not that there isn't one. I would let it go for a long time, perhaps only on tests 5&8, as Thor86 mentioned.

I've found that memtest86 has always found bad memory, eventually - however, one on of my systems it did need 48 hours before it flagged errors.

By contrast, my experience with WMD has always had it find errors within a single pass (on the exact same system that would only show a couple of errors approx once every 20 passes on memtest, it would show thousands of errors within a few minutes of starting the test).

heh, /me wondering if any of the above posters actually meant memtest86+ (newer) and not the older version (memtest86).
