Server crashing, Trying to run Memtest just resets the system

[mbutler76]

My server ran fine all last week, but then on Friday and again on Sunday it will just randomly shut down every docker container. When I try to restart them I get an Execution Error, error 403. I've attached my diagnostics zip from Sunday afternoon. 

 

I have also tried to run memtestx86 from the boot up options, but all it does is restart my system. My motherboard screen comes back up and then I get the choices of booting UnRaid.

 

Do I just have bad RAM? It was bought brand new, but this is what I am currently thinking

The memtest included with Unraid only runs if you are booting in Legacy/CSM mode.   If you want a version that will run with UEFI boot you can get one from memtest86.com

Thank you, I will download and run this now

My machine won't boot the USB with memtest86 on it. From what I understand I need to change my Compatibility Support Module from Legacy to UEFI. But, this option is always greyed out in my BIOS. I've seen some others mention that having a cpu with igpu causes this. But I don't have anything to swap out with. 

 

Any suggestions?

Get the Passmark memtest, that one is UEFI only.

[mbutler76]

The link on the passmark website just takes me to memtest86.com which is what I have already tried. My machine won't boot the USB

That ones boots UEFI, I've used it myself, if you can't boot UEFI and CSM there are other issues, or the flash drive was not created correctly.

These are my setting options in my BIOS. I have tried the OS type as Other OS and Windows UEFI. Every time I save and exit, I just get brought right back to the BIOS. Do you see any settings that I might have wrong?

I had downloaded an older version of memtest  God I feel dumb. It is running now with the current version

 

 

Edit: Been running for just a few minutes now, and there are over 600 errors. I think I have found the problem

I dealt with memory issues a few weeks ago.  Spent hours (days?) of my life I'll never get back running memtest over and over.  Here are some suggestions...

 

1) In my experience, if there were going to be errors, it found them by Test 7.  If you have to run a bunch of tests for different scenarios (DIMMS, slots, speeds, timings, etc), I wouldn't run the entire test.  Stop after Test 7.  When you think you have a stable system, then you can run the entire test.  Even run multiple passes overnight.

2) Check your memory speeds timings in the BIOS, and set them to match the memory specs.  My ASUS Z790 board was not auto-populating timings correctly (I'm talking a about the 4 main timings).  Setting the timings manually fixed the vast majority of the errors.

3) If you have another system that supports your memory, check your DIMMs in that system, one stick at a time to determine if the DIMMS are good.  Otherwise, if you can find a dimm/slot combination that results in 0 errors, you can use that to identify which DIMMS or slots are causing errors.

4) I had different results from memtest for different slots on my server mobo.  Slots 1 and 3 threw errors every time, slots 2 and 4 had no errors (where slot 1 is closest to the CPU, slot 4 is furthest).

5) If you find another set of memory to test with, don't assume that kit is "good" just because you weren't having errors with it before.  I pulled my main desktop ram to test in my server, and still got errors.  Turns out two of my dimms from my desktop were bad, too, when I ran memtest on my desktop.

 

Ultimately I decided to switch motherboards and get ECC memory, because I saw the chaos that memory errors can cause in Unraid.
