I ran it twice. Maybe memory testing is a lot faster now or the test is perfunctory, it only took about 10 minutes to run each time.
I’m pretty sure it is flaky memory but it only fails sporadically.
The computer recognizes a problem, does a memory dump and shuts down. It happened today, the last time it did it was a couple of weeks ago. I think the built in memory checker doesn’t check each location enough time to find the weak bit.
Memory dump isn’t always about memory. When I overclock a cpu and the system can’t handle it at that setting and I am able to get into Windows it will sometimes do a memory dump. Windows 7 64 is less forgiving when it comes to CPU issues it seems to me(an opinion).
