Solved BSOD on Windows 8.1 Pro: memory_corruption & ntkrnlmp.exe

Hi,

I have a Windows 8.1 Pro machine that was built by a custom computer vendor. I've had it since mid December of 2013, and after about a month of owning it I experience the first BSOD induced restart. Since then it has BSOD induced restarted four more times. The interval between BSOD induced restarts has also been getting shorter: month -> two weeks -> week -> three days -> two days. When I examined the .dmp files it said the problem was caused by: memory_corruption and ntkrnlmp.exe. Any thoughts/help is greatly appreciated.

Thanks,

Tom

Custom vendor, heh? Did they use all the same RAM modules or different? heh

There's a hardware issue. Most likely RAM mismatch or timings unwell in bios.

Please make a screenshot of the first tab of CPU-Z. One also of the Memory tab. And one each for each stick of RAM of the SPD tab. Attach the screenshots, please.

Yep, AVA direct and first time I've ever dealt with one. They better have used the same RAM modules, but I'd have to check on that.

I was afraid of it being a RAM issue. I'll get the screenshots.

I'm checking on things with software now.

The screenshots are attached.

It all looks decent. If it were me, I'd go into the bios and set the RAM voltage to ~1.45v, test and if necessary, try 1.5v.

Okay, I'll give that a shot. I'm going to update the Bios. Did some reading on the mother board and seems to be a string of negative reviews lately, which wasn't the case when I bought it. Really hope it isn't a MB issue.

I went ahead and ran Windows Driver Verifier and looks like it identified the Nvidia driver as a culprit. I've attached the SF zip file again with the new .dmp files. I'm wondering if this could be related or is totally independent of the other issue.

If issues persist, the memory is defective.

I went ahead and ran Memtest86+ with all for memory sticks in place and got an error. I then ran on each individually and there were not errors. I ran again on all sticks and this time got no errors. The only thing I can think of is that one of the sticks was not pushed in all the way (noticed they were difficult to get in place and had to apply significant pressure to get in place) or one was dislodged in shipping. This seems to have taken care of the problem. Thanks MC for pointing me in the right direction!
