In general it is better to run multiple passes. Here are three typical lengths of testing you might use:. When I suspect a RAM problem e. Dell computers with diagnostic lights I run memtest on one RAM module at a time in the first slot for hrs. Although memtest works the majority of the time, it failed me a couple of times. I then tested it on a completely different computer, same thing, no errors. Operating system was completely unstable but no errors on memtest.
I then used a different software named "PC-Check" from Eurosoft which is very similar to memtest but uses different algorithms. It is also bootable, does not need any operating system. It detected errors in less than 5 minutes. I then was able to send the module to Corsair RMA and get a replacement. So, memtest is very good but not always enough.
I currently use memtest and PC-check to check memory. If memtest fails to detect errors, PC check certainly will and vice versa. And trust me, it happens more often than one would think. I'd say 3 passes is generally enough. If you want to be extra sure, do 8 or 9 passes, since Jeff saw errors in one case only on his 7th or later pass , but that can take forever! As a general rule of thumb, I think LAwLz got it correct here when she said emphasis added :.
In most cases memtest will start spitting out errors within a minute if the RAM stick is bad. After 3 passes it's Here is something to keep in mind though. Memtest will only prove that your RAM has issues, but it will not prove that it does not have issues even after 10 hours of tests. Even if you run the test times you can not be sure that it would not spit out an error after the th run.
And she also believes 8 hrs is good enough but I'd add: so long as at least 3 passes are achieved during this time --if not, keep going until you get at least 3 passes :. I will be running it overnight, so that will be about 8 hours. If you want to be as sure as practically possible, I'd say let it run overnight. If you don't get any errors after 8 hours of intense searching for errors, then it's pretty safe to say they are fine.
Given that, after one pass, it displays Pass complete, no errors, press Esc to exit , I always assumed that's sufficient. Reason is - memtest does not just test memory. It will error out in three other important cases:. Sign up to join this community. The best answers are voted up and rise to the top.
