RAM Error Conundrum

post #1 of 3
Thread Starter 
Well, this is a bit of a long story, so I'll start with the all-important relevant system specs, since this system isn't in my signature anymore.

While I used it for some overclocking before, all of it is currently running at stock.

Back in January, some BSODs on that system started grabbing my attention (All pointing to memory issues). I did some Memtest passes on the RAM on that computer, and two of the four sticks came up with errors every time, regardless of the configuration. Swapping sticks among slots produced no different results; slots 0 and 2 always came up with errors. I moved to another computer and tested the sticks in all configurations imaginable, from each individually to random configurations of the four sticks. Sure enough, they all passed time and time again. I even swapped the i7 870 with an i3 530 just to see if it could have been the processor. The errors remained. So it was the motherboard.

I didn't have time in January to RMA the motherboard since I went back to college, but EVGA agreed with my assessment that the board was bad, and when I returned in May, I got back to RMAing the board (Though I didn't ship it to them until late July). When it arrived a week or so ago, I installed everything again and reinstalled Windows. All was well at first, but RAM-related BSODs came back shortly after. I didn't believe this was possible, since I was effectively on a brand new board. I didn't think I'd RMA a lemon and get a lemon in return.

So I turned my attention to other possible problems. I ran Memtest on that system again, and slot 0 was consistently bad, again, regardless of the memory stick arrangement. Memtest would barely reach three seconds into a test, when the error report would immediately come up, stop the test, and report that slot 0 is producing errors. Now I'm thinking the issue might very well be the processor. Perhaps the board was indeed the problem the first time, but now I truly don't know.

I'm going to get on swapping the processors like I did the first time, but I need some input. What else could be causing this problem? I have a sneaking suspicion the IMC on the i7 was bad all along. Could there be something else I'm overlooking?

EDIT: Swapped the i7 with an i3, same error popped up, computer now with an i7 tests the same RAM perfectly. That leaves the motherboard or something else as the problem.

I say you let EVGA handle it.

It is totally possible you got a bad board back. It is usually a pretty rare fluke, but it happens.

I know this sounds stupid, but what about a PSU issue? It could just be faulty and causing damage to your ram sockets?

It is a total long shot, but short of buying new ram, you seem to have exhausted the normal issues.

I was thinking of that, but I weighed against it in favor of other issues, since the power supply has been a workhorse for 6 years now, and its voltages check out. It's an Ultra X-Connect 400w, for better or for worse. It hasn't failed me yet.

I was hoping I missed something, though, and I feel as though I still am.
