Alright, I tested my memory for several hours today. I started with removing one stick, leaving the stick in DIMM 1 intact. I ran Memtest86+ with stick 1 in DIMM 1, no errors:
Then I ran stick 2 in DIMM 1, 2 passes, no errors:
Then I put stick 2 into DIMM 2, 2 passes, no errors:
Then I ran both sticks occupying both DIMM slots for just over 4 hours, 4 passes, no errors:
I don't see a reason to run the test any longer based on what I've read online, considering the prevailing wisdom that most any defects would show up in 1 or 2 passes if they were going to. I'd tend to agree with that logic for something as fragile and volatile as RAM.
The motherboard I'm using is Gigabyte GA-Z68X-UD3H-B3, which isn't top of the line, I know, but it wasn't cheap!
@ranchhand1, I've run hard drive testing with Sea Tools and no errors popped up, along with all SMART values being nominal.
I happened to read this post that sounds like the problem I had starting a year ago:
Too bad he didn't get it resolved either....
