BSOD several times bugcheck 0x00000050 in Event log every time

I see what you mean about the slots. If I can identify this to being a motherboard error that would be great - I'll just replace it.

A small update on my BSOD situation.

I moved the 4x*8GB DIMM 32 GB of RAM suspected of maybe causing the BSOD issue to a different computer and left the memory test running for a few days - no errors were found on it. In total it ran for 118 hours and completed 22 passes in the old PC - see attached image. I guess that rules out the memory itself as a source of the problem.

During this 118 hours of testing I took the 4x4GB DIMMS out of the old computer and used them in the new computer and I experienced no BSOD's or other issues at all, it was working just fine with all DIMM slots filled.

So both computers had all DIMM sockets filled during these tests.

When removing the 4x8GB DIMMS to test them on the spare computer I noticed that one of them came out of the slot a little too easily when I was removing it - I'm wondering it it was somehow not fitted correctly and therefore this issue could have been caused due to vibration / bad fitting of the one of the modules. Have you come across this before ?

I've now swapped the 4x8GB DIMMS back in the new computer and I'll see what happens over the next days / weeks.

I'm running the same memory tests on the 4x4 GB DIMMS on the spare PC just for good measure.

If it starts crashing again I'll come back to this thread.

Thanks for the help !

As I told earlier in the post #9, memory error is not only for failing RAM sticks, but for failing DIMM slots too. Doing the test on different computer, you ruled the chance to test the slots out.

Ok, I know the 8GB DIMMS are good as I tested them for 118 hours in a different computer.

I didn't just sit there waiting while this test took place.

I have a full spare set of DIMMS so I took the spare 4 x 4GB DIMMS I have and put them into the computer that has been crashing. I turned it on and It did not crash once during the 118 hours I was testing the 8GB DIMMS on the other computer.

So all slots were active on the computer that's been crashing for this 118 hour period and it did not crash at all - in fact there were no issues using the 4GB DIMMS in all slots.

The 8GB DIMMS passed the test no problem on the other computer.

Is it possible the computer works ok with 4GB DIMMS but only has a problem with 8GB DIMMS for some reason and this is somehow caused by the sockets ?

I'm tempted to just go out and buy another motherboard, at this point I don't really care about the cost. Motherboards are not so expensive.

This is a new computer with very little installed on it. since I made the purchase I have not installed much on it :

Windows 7
Video card device driver
Motherboard device drivers
Firefox browser
Truecrypt
Vmware Player
FileZilla
Python 2.7

That's it, nothing else has been intsalled. The rest is all inside Virtual Machines which run on the VMWare player.

Would I be wasting my time doing more tests - better to just replace the motherboard ?

EDIT : When I first purchased this new PC I installed a couple of different linux distro's on it to do some tests and that randomly crashed a few times as well. Both Centos and Ubuntu crashed randomly during the few days I was running some tests with it prior to installing windows where these BSOD issues started.

I found some more information on this.

The motherboard I have in my computer is notorious for BSOD's when all 4 DIMM slots are used.

It's the Gigabyte Z87-D3HP

A lot of people can't get any set of 4 DIMMS running in this motherboard without constant crashes.

For me the 4GB DIMMS work perfectly all the time but the 8GB DIMMS don't work.

As a note to others, if you have 4 DIMMS and the Gigabyte Z87-D3HP motherboard - check the official Gigabyte thread here : http://forum.giga-byte.co.uk/index.p...c,13267.0.html

Edit - apparently this issue affects other Z87 motherboards as well, not just this specific model.
