Can't get to login page

[ZosoPage1963]

Hey all.  I have an interesting problem that has arisen over the past 2 days.  In short, when I wake up in the morning and try to login to my server, I can't.  The IP of my server is 192.168.1.49.  I get no response or I have got a nginx 500 internal server error.  I have recently added 2-8gig sticks of RAM, and I have recently swapped letsencryt to the new repository for the SWAG update.  I have also added a 1TB SSD to run my VM on an unassigned drive.  When this happens, I can get to my bitwarden website, Plex seems to be running fine, but Nextcloud is down completely which leads me to think something is wrong with SWAG.  The only thing I changed when I swapped out the repository was just that.  Or, could it be a RAM issue where one of the sticks is misbehaving.  I have 2-16Gig sticks and 2-8-Gig Sticks in my humble server.  I am not sure how to get the syslogs when this is occurring since the only way to access the server is to reboot.  Any help in pointing to a solution would be appreciated.

I'd restart in safe mode first and see what happens.  If still the same thing, then edit both /config/docker.cfg (set DOCKER_ENABLED="yes" to be "no") and domain.cfg (set SERVICE="enabled" to "disable") reboot and retry.

Thanks Squid.  I will try these suggestions tonight and see if I can access the server in the morning.

booted up in safe mode, running parity check, and I have received general protection fault: 0000 [#1] SMP NOPTI  

 

any ideas?  it looks like the parity check slowed down immensely but it is still going.

from syslog:

Have you done memtest?

its on my list... I just replaced RAM because I thought the same thing... after the parity check, I will run the memtest and let it go overnight.

in my setup, I have 4 ddr4-3200 16G sticks.  2 were bought 6 months ago, 2 were bought this last tuesday.  They are both Balistix, but one of them is called Balistix Sport.  I know this is not an Unraid issue any longer, but maybe, just maybe someone would be nice to school me on why I am obviously having a memory issue when I am using the same speed memory?

So memtest failed?

[ZosoPage1963]

memtest failed when all 4 sticks were put in together.  If I did 2 at a time of the same exact type, it passed in each of the slots (4 slots).  I must not be understanding memory when it says dd4, 3200, I thought it would be ok to purchase.

looks like you're mixing single rank with dual between those two types of sticks.  Don't know if that is considered a big no-no.  But since you're running dual rank in [some] configuration with 4 sticks, try lowering the RAM speed to 1866, since 2133 might be considered an overclock.

thanks for the reply!!! How can you tell the difference?  Did I miss something stupid or is it just an experience thing?

Just looking through your diagnostics says everything about your configuration, which is nice to spot things like this.  Looking at system\meminfo.txt in the diagnostics, it lists details about your memory. Two of the sticks say this:

Speed: 2133 MT/s
Manufacturer: Unknown
Serial Number: E0F78509
Asset Tag: Not Specified
Part Number: BLS16G4D32AESB.M16FE
Rank: 2

While two other say this:

Speed: 2133 MT/s
Manufacturer: Unknown
Serial Number: 00000000
Asset Tag: Not Specified
Part Number: F4-3200C16-8GVKB
Rank: 1

Then referring to this for the proper speed

Awesome, thank you for the help.  I thought that the speed of the RAM was reflected in the number after DDR4... in my case, it is 3200.  RAM has always been difficult for me, and I thought I had it worked out, but obviously, I haven't and need to read a bit more.  Thanks for the schooling.

No prob. and that is the advertised speed that the memory itself can operate at - but it is dependent on if the CPU and motherboard support that speed as well.  In the case of Ryzen, there are a lot of factors that come into play.

Yeah, I like AMD and just recently bough my first AMD CPU since the Athlon 64X2, but wish AMD did the same as Intel for RAM speeds, i.e. 10th gen Core CPUs support up to 2933MHz, doesn't matter if you have one or all DIMMs slots used, Ryzen 3rd gen supports "up to" 3200Mhz, most users then don't know that max speed is based on number of DIMMs/ranks used.

so, since I believe I have 1st gen Ryzen, I should go into my bios and downgrade the DDR4-3200 RAM that I have to the max that is allowed.  Or, if I am leaving it at 3200, I am basically overclocking the RAM.  Correct?  Or, even better... dump Ryzen and go with Intel and swap motherboard and cpu out...

Correct, respect max speeds mentioned here:

I believe you have a second gen Ryzen, but then again AMD's naming convention confuses me.  Set the memory speed to 1866 in the bios and try running a few cycles of memtest with all of your RAM installed and see how that goes.  If it passes then that was probably the cause of all of your issues.

Since you already have it, might as well stick with it and see if the above fixes your problems.

My last AMD system was an Athlon 64x2 as well.  And I would never have known about the Ryzen memory speed issues if it weren't for this forum.  I suspect windows just handles these problems better when the memory is overclocked. either that or people just figure windows is being windows when it crashes.
