Persistent BSOD ntoskrnl.exe

Ok wierd. Dell SupportAssist is no longer on the systme but Intel Driver Agent was. I uninstalled.

Just got another one. Please help.

Hi Ryan,

Looking at the varying bugcheck codes and the lack of an obvious pattern to what is causing this issue, I'd recommend you do a memory test of all of your DRAM. Given that you have eight 16GB DIMMs installed, and the time it would take to test all of that in one session, consider the following strategy:

At night remove all but one DIMM from the computer (keep placing the single DIMM into slot 1) and start the memory test before you go to bed. In the morning check the results, and reinstall the other DIMMs so you can use your computer normally until the late evening. You would then continue this process until you have verified all DIMMs are error-free.

I also see there have been a number of firmware updates for your ASRock X399 motherboard. It's definitely worth a shot to see if the updates fix your stability issues.

Hey Spectrum thanks for your suggestion. It would be prohibitive for me to test RAM at this time using either your strategy or to test in one session. After the current project I'm on wraps I'm going to test RAM in one session, address any findings from that and then clean install Windows. Until that occurs I think I'm going to cease posting logs and thanks to everyone who has contributed to this thread.
cheers-

Hey guys I'm back and am going to plan on using Spectrum's DIMM testing strategy above. Given that I've Furmarked (per instructions) each GPU (of which ther are a total of 4) and am using a brand new mobo, I'm thinking the culprit is either RAM or CPU. Is this a reasonable assumption?

It's not how I would do it because I'm in agreement with computix in this thread about the effectiveness of software diagnostic utilities when testing DDR4. I've seen too many instances of DDR4 passing such diagnostics only to find out in the end that a DIMM was faulty.

Have you found a reliable way of reproducing a crash?

Would you be able to use your computer as you normally do with half the memory removed temporarily?

Regarding if I've been able to reliably reproduce the crash, the short answer is no. At one point I thought I had traced it to the initiation of a GPU rendering session however after doing a complete clean install of Win10 I got a BSOD without initiating a GPU session.

I would be willing to use the system with 0.5x RAM... Can you describe this process (aside from the obvious) in greater detail please?

I'd remove half the memory but in such a way that preservers the dual channel configuration of the remaining memory and then use the system as you normally would to see if the problems continue - you'd have to have a sense of how long is long enough to be confident you're not having the problem anymore. After that amount of time or if the problems continue I'd then remove the memory in use at that time and replace it with the memory you'd removed previously to see if the problem continues. Basically the idea is to try and isolate bad DIMM(s). Each iteration of the test should narrow down the group of possibly bad DIMM(s) by half until the bad DIMM(s) are revealed; unless the problem lies elsewhere.

This has been the most reliable method I've seen to actually find a faulty DDR4 DIMM that evaded detection by the usual software diagnostic tools.

Interesting... Can you describe "...in such a way that preservers the dual channel configuration of the remaining memory..." in further detail please?

It looks like page 20 of the user manual for your motherboard talks about it. I didn't realize your motherboard could do quad and triple channel - I assumed single and double. Your current configuration is shown in column 3, I believe. So I'd try the configuration in column 2 to begin with which should be dual channel but with 4 DIMMs. After testing I'd switch those 4 DIMMs for the other 4 DIMMs but in the same configuration. Then, if necessary and/or possible I'd try the column 1 configuration with 2 DIMMs, and so on... I wouldn't bother with triple channel.

Does that make sense?
