Hi everybody,

This is my first post here. I tried asking in the support forums of MSI but no one seems to know the answer. (

Current build
Intel Celeron G1610, now switched with a Intel I7 3770k (had the same problems with both processors)
MSI Z77A-G43
2x4gb Corsair Vengeance LD low voltage 1600 mhz 1.35 v dual channel kit
Seasonic 620w PSU (I also tested with a 850W PSU from Cooler Master and had the same problems)
Saphire 7850 2gb GDDRAM5 (i also tested without this board inside, just running on the CPU graphics and had the same problems)

My problem is the following. Either my RAM is bad, either it is incompatible with my motherboard. I keep getting constant BSOD's which are only partially solved by increasing the voltage. At 1.35V (the default value that XMP sets on the RAM when I enable it) it crashes like every 10 minutes. At 1.5V it crashes after a couple of hours, and at 1.65V it doesn't seem to crash but I haven't tested it properly and long enough yet.

At first I thought it might be a compatibility issue but I switched my 2x4gb kit with another 2x4gb kit from a coleague (another Corsair kit but a different model, with 1600mhz and 1.65V specification). From this point I had no further BSOD's, but my coleague started to have the exact same ones I had smile.gif At this point I'd be tempted to say the RAM is bad but there still is a slight chance that it might be incompatible with both motherboards (the other one is a pretty old Gigabyte model)

The thing is, the RAM passed a 12+ hour Memtest. I don't want to send it back to the store for warranty and then have it sent back to me the same as it was. They might not see the problem there. In this case I would get charged some extra $ for sending a good product to them, claiming that it is broken and I'd also have to wait around for up to 2 weeks for my RAM to get back.

To come to my question, did any of you have similar problems? Do you know a way in which I can check and know for sure if the ram is broken?

Thank you for your help!

PS: this is how a typical crash dump looks (analysed with the "Who Crashed" software):
On Sun 2/24/2013 7:08:04 AM GMT your computer crashed
crash dump file: C:\Windows\Minidump\022413-9204-02.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x71F00)
Bugcheck code: 0x3B (0xC0000005, 0xFFFFF80002CEF09D, 0xFFFFF88002A11C10, 0x0)
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.
