No need to apologize. Any input is welcome at this point after so many trials and errors without reaching any sort of conclusion.

Even though my memory tests alright with memtest and Hyper PI, I still don't ignore the fact it could very well be faulty in some way. Perhaps it's an error so small that only in very specific conditions it causes a system crash.

I'm considering buying some other RAM modules and see if this changes anything. My only concern is that, if my RAM is not the issue, I could be introducing yet another variable prone to errors, given that memory is the most sensitive component in any computer when it comes to stability, in my experience.

If I go that route, I have the second issue of getting appropriate modules. Here in South America, I don't have the luxury if being picky about what brand of memory to chose from. Geil, Kingstom and Corsair are the most abundant brands available, but their respective top notch models are quite expensive and I would really hate to expend so much money on something that could not fix my issue. I have found at a trusted store some g.skill ram, however I've been reading lately at the g.skill forums that users have been having problems with their rams and Asus mobos even though the modules are listed in the QVLists.

I don't know if I will run the full test tonight or some other day, but let's see what comes up this time around.

I would get Corsair in case the ram is crap or incompatible to AMD IMC.

You should troubleshoot with "el cheapo" RAM maybe borrowed from some friend.
Also try only one stick of that RAM at a time you may have unidentical modules ,it happened with one pair of Kingston for me and they would error in dual channel ,while each stick was ok at a time.

Great news guys.

I ran memtest86 and guess what? It's consistently crashing at test #7. It doesn't even throw any sort of error message in memtest, the computer simply freezes. I've repeated this result more than once. I never imagined I would be happy to find a way to crash my computer, but life and its sense of humor.

Gonna get some replacement memory today and see how it goes. Hopefully this will solve all my issues. I will post back with results as I go.

Got myself a G.Skill ECO Series 4GB (2x2GB) 1600MHz pair (model F3-12800CL7D-4GBECO). It's listed on my mobo's QVL and was available for a reasonable price.

Really nice chips, 7-8-7-24 2T @ 1.35v. Installed fine, only had to manually set the timings and speed at Bios (defaults to 1333mhz 9-9-9). Ran two passes of memtest without any issues and I swear my computer booted up faster than usual (~6/8 seconds faster).

This weekend I will run some games and see how my computer behaves. Not much spare time lately. I will keep updating this thread if anyone ever runs into a similar problem.

I ve told you the RAM tests must be made properly

How many hours have you runned Memtest or how many passes did you do on the test 7.

I recommend you to do test 5 and 7 (25 passes) on the new RAM modules as well.
Have you isolated the RAM module with issues ?
Because it can happen to be either a RAM slot issue or even a CPU controller issue if the error is not localized on one of the RAM sticks.
Good luck with your new RAM.

Well, bumping my own old thread as I said I would.

It has been two months now since I replaced my memory and I've been crash-free ever since.

So, in case anyone ever finds (him/her)self in a similar situation, with unexplainable system crashes and that dreaded Event ID 41 (Kernel Power) in the system logs with a 0x0 bugcheck code, this is what worked for me.

Yes, I'm writing this for you that searched google up and down and somehow ended up in here. I replaced my motherboard before RAM and it didn't solve my problems. The RAM was the culprit even though it passed memtest, at first. It wasn't until several attempts later that a error popped up, so yes, your system might be prime/memtest/(insert stability tester here) stable, but that doesn't 100% guarantee that something you just tested is working properly.
