Basically, all you really want to know is if it completed one pass without any errors. Memtest is a small routine that checks all memory addresses for errors that would indicate a faulty stick of RAM.

Memtest should be run overnight, at least 12 passes. Any error is unacceptable.

Version 4.2 is current.

Hello,

So what should I do, throw away the RAM since it is a failed test?

Test Time: 1 second

Could not do an overnight test.

You can run it again for a '2nd opinion' if you want. But if it fails on the first pass, the RAM is either faulty or the memory controller is. Most likely the RAM. That's why I said you really only need to run it for one pass if you're not O/Cing and testing for stability. Memtest will find the error in 1 pass.

I am going to do the isolate 1 RAM stick diagnostic test.

If it fails on one pass, I am going to throw it in the garbage.

Don't do that... recycle it.

Btw, if you buy memory always buy in matching pairs for populating 2 slots, and matching 4's if populating 4 slots. If your system uses triple channel memory (3 or 6 slots), buy in sets of 3 or 6. Keeping volatge and timings the same is critical for problem free usage.
